Strange behaviour with views

Normally when I write a blog post, it’s about sharing some cool features, new functionality, etc. However this post is going to be a little different, because I don’t actually have an answer (yet!) to what is going on here.

Let me explain the situation.

I’m needing to show some very specific data for reference purposes. For the purposes of this, let’s say that I’m looking at Contacts, and needing to report on Phone Calls. The reason is to identify Contacts who are frequent callers. My criteria are as follows:

  • At least one phone call (that has the Contact as the Regarding value) need to have a specific field set
  • At least one phone call (that has the Contact as the Regarding value) needs to have its Activity Status as Open

These two conditions are separate. So the contact essentially needs to have at least 2 phone calls against them, with each one meeting one of the conditions. There can be more than 1 phone call record with the same condition – that’s not an issue here.

Back in the (good old) day, I’d have written some cool SQL to return this data. Two Left Outer Joins, and we’d be done. However I can’t do that now (I’ve recently started dipping into FetchXML, which is an entirely other story to cover at some point). So I’m having to use the Advanced Find to check that I’m getting the right data.

This isn’t the easiest of things to do. I’m needing to start from Contact, go to Phone Call, go back up to Contact, & go back down to Phone Call. But hey, this is what it looks like:

So with this set up, I run the query, and get some results (in this specific scenario/time, there are 3 results). I go through the data to check that the results are actually satisfying my requirements, which they are:

Wonderful – let’s move forward then!

My next step is to look to set this up as a system view. To do this, I go to the Power Apps Maker (http://make.powerapps.com/), open my solution & find the Contact entity. Opening it, I switch to the Views tab:

I create a new view, add the columns I need, and then open up the Filter Criteria to start setting this up. I’m using the Advanced Find as a reference guide for the conditions I’m needing to use. Going through it, I replicate the values across:

That looks about the same as the Advanced Find, right? It’s laid out slightly differently, but that’s just the designer. OK – let’s go ahead to save/publish it, and see it it in the app:

Hold on. There’s only 1 record showing up there. Admittedly it’s in the list that came from Advanced Find, but what’s happened to the other 2 records?

So I go to check the data. I had already done this before, but I thought that perhaps I overlooked something, so I checked again. Nope – all of the data is fine/correct. There should indeed be 3 records showing up in the system view, but 2 are missing…

Note: As an aside, I do know that this isn’t permissions related. I’m doing all of this as a systems administrator with full privileges to everything. So it’s not that

OK – next steps:

  • Clear browser cache, reload and see if they’re showing up (useful tip – Control+F5 does this!). Nope, they’re not showing
  • Use Incognito mode, log in and see if they’re showing there. No, they’re still hiding away
  • Use a different browser, with a different system administrator login. Unbelievably they’re still being very shy, and refusing to appear!

Even more confusing about all of this is something truly perplexing. I can open up Advanced Find, select the system view (without doing ANYTHING else) & click ‘Results’. When doing this, all of the records appear! So in the entity view they’re not, but when I use that same system view through Advanced Find, they are!

I’m scratching my head at this. It just doesn’t make sense. I have no idea why this is happening. Reaching out to others, they also don’t seem to have any idea either.

My next step (I’m feeling SO proud of this, and so dev!) was to check the FetchXML. Perhaps there was something underlying in it that’s causing this? Using the FetchXML Builder in XrmToolBox, I loaded both views up, and compared them. It’s crazy – they seem to be exactly the same! (well, some cosmetic differences with where aliases appeared on the line, but this wouldn’t affect it):

At this point, I’m thinking that there are some magic elves under the hood, squirrelling away the data. It has to be the only logical reason for this, right?

The only thing I could find in the FetchXML that might make a difference is that there’s a ‘Distinct’ clause at the top of it in the one that’s working:

Why this would cause the issue, I have NO idea. Views return distinct results in them anyhow, so I’m not sure what this is actually doing here.

Regardless, using FetchXML Builder I updated the code, and WOW – it worked! I’m now returning 3 records in my system view! Absolutely strange, but hey – if it’s working now, who am I to question it…

I’m going to try to raise this through official Microsoft Channels, and see what I might be able to find out from them. However if you’ve come across this (or similar), or have some ideas about how to work around it, I’d LOVE to hear from you!

Omnichannel – Wave 2 2020

Yesterday was an extremely exciting day, for a number of reason! The main reason (& the purpose of this article) is that the release notes for Wave 2 2020 dropped. This covers Dynamics 365 (https://docs.microsoft.com/en-us/dynamics365-release-plan/2020wave2/) and Power Platform (https://docs.microsoft.com/en-us/power-platform-release-plan/2020wave2/). I’ve been quite eager to see (& talk about) some of the features that will be in it, so here goes!

Now there’s obviously a lot of different stuff in there, covering all of the different first party apps in Dynamics 365, as well as functionality for the different parts of the Power Platform. I’m going to focus on the Omnichannel features, as after all that’s what I (mostly) talk about 🙂

As I’ve done before, I’m going to include the dates that are applicable (at this point in time) for each time.

Agent suggestions for similar cases

Public preview – October 2020. No current date for GA release

Reader Question: What should I do if a project sells in Hollywood ...

Customer service agents will usually use multiple resources to efficiently handle & resolve customer cases. When doing so, the ideal is to provided consistent responses across agents & sessions. Carrying this out can involve knowledge articles, involving other agents, or reviewing active/similar cases.

The aim is to therefore improve this to enable the agents to be more efficient. Items such as being able to identify other cases that similar actions have occurred will result in a much more empowered experience.

The key highlights for this new feature include:

  • AI driven case suggestions bases on the context & historical success rate
  • Secondary actions that can be taken, such as collaboration with an expert
  • Continuous improvement of the recommendation model through a comprehensive feedback mechanism

Embedding chats in mobile experience

GA – October 2020

Until now, the only way possible for customers to engage with Omnichannel customer support on mobile has been through a mobile browser. This hasn’t always been the best of experiences.

This feature allows business with mobile applications to provide customers the ability to engage with customer service directly within the mobile app. There are two options available for this across iOS & Android devices:

  • By embedding the Omnichannel chat widget into an iFrame, with minimal code customisation. The colour & logo can be set through the Omnichannel Administrator app. This method includes a sample app on AppSource with examples for common scenarios
  • Through the React Native Mobile SDK for Omnichannel for Customer Service. This will allow developers to build fully customised chat widgets in mobile apps

Persistent messaging for chat

GA – October 2020

One of the main challenges around chat is that when a conversation is closed, the history is accessible the the chat transcript. It’s not easily visible in the chat conversation history. Asynchronous messaging channels such as WhatsApp don’t have this ‘restriction’, as the chat history is directly available in the session.

If an agent needs to go look up the chat history, it can cause a delay in responding to the customer whilst it’s located, opened & read. This in turn can degrade the customer experience.

In this new feature, admins are able to enable persistent messaging, so that the customers previous conversation shows in the actual conversation window. This in turn allows the agent to have the full context of the customers previous engagement before responding.

Outbound messaging

Public preview – August 2020. GA October 2020

There are occasions when organisations need to proactively reach out to customers. This could be to notify them of a case update, regulatory information, upcoming appointments, etc. Being able to do this via the customers preferred method of communication is important in delivery best-of-class service

With this feature, organisations will be able to dynamically message their customers based on specific events through supported channels. This includes the following capabilities:

  • Creating message templates that can be adopted for outbound messages
  • Configure outbound messages based on specific events on any entity, & send messages when these events are triggered

The customer will now be able to respond back upon receiving one of the messages. This response will be treated like any other incoming conversation in Omnichannel. It will flow through the appropriate routing & work distributions, agent assignment, etc, and the agent will be able to respond back to the customer in real time

Post-conversation surveys using Forms Pro

Public preview – August 2020. GA – October 2020

Until now, there was no (easy) method for post-conversation surveys to be sent out to customers. Businesses wish to ensure that customer satisfaction is met, and often make use of such things. Custom Power Automate actions could be implemented, but this obviously takes additional time &/or resource to develop.

With this new feature, Omnichannel administrators can configure post conversations surveys using Forms Pro. These can be presented natively as part of the customer experience to provide feedback. There’s also support for sending offline surverys through one of the various enabled channels.

Real-time language translation of messages

Public preview – August 2020. GA – October 2020

Language Translator - Apps on Google Play

Customers would like to receive support in their native language. Businesses are not always able to do this, as it would require having staff who can communicate in different languages to their customers.

In this feature, real-time translation of messages is carried out between the customer & the support agent. It’s also available for the internal collaboration between agents. It’s enabled as a plug-in that exposes API’s to bring in 3rd party translation services, & also provides a native implementation through Azure Cognitive Services.

This is a feature that I can see being used heavily by not only multi-national organisations, but also by by smaller national-based organisations that have an international customer base

Agent personalisation of quick replies

What is Quick Response in S Planner of Samsung Galaxy Note2(GT ...

Agents spend a considerable amount of time engaging with customers. We already have quick responses within Omnichannel to save agents time in typing replies, & to deliver consistent replies.

However these can’t be personalised for individual agents to represent their identity. This new feature allows the pre-configured quick responses to be customised by agents to represent their styles. With this, they can then address communication scenarios in a manner that’s common & personal to them.

Agent personalisation of sound notifications

Public preview – September 2020. GA – October 2020

This feature enables agents to customise sound notifications for incoming conversations so that they can easily distinguish between different sessions. It will also allow them to
differentiate their sessions from others around them in a call centre setting.

Agent suggestions for knowledge

Public preview – September 2020. GA – October 2020

Agents typically use several different resources to efficiently resolve customer cases. These include knowledge articles, collaboration with other agents, and reviewing other cases. Up until now, this has all be done manually.

The new feature for this uses AI to proactively surface relevant knowledge articles, taking case context & previous history into account. It also includes a comprehensive feedback mechanism to continuously improve the recommendation model.

Experience designer for multi-session apps

Public preview – September 2020. GA – October 2020

The experience designer is an out-of-the-box solution that lets organisations create targeted app experiences, to be used by agents & supervisors. Administrators can select specific channels & tool to be used by these profiles, as an alternative to building & maintaining custom apps.

All in all, I think that there are some really helpful additions to the core Omnichannel product, aimed at making the customer & agent experiences more productive. I’m looking forward to getting hands on with these, and writing about them!

Canvas Apps, Collections & Dropdown Fields

This post is based around some recent work that I’ve been doing, which includes canvas apps. For those of you who aren’t familiar with canvas apps, imagine if PowerPoint & Excel had a baby! Though I’m expecting most people who are reading this to already know all about them 🙂

So enough with the waffle, let’s get on with things…let me paint the scenario for you.

The app is aimed to be used by a contact centre. Part of their function is to capture address information. So far this has been done absolutely manually. The issue with this is that data can be typed incorrectly, or in the wrong fields. We’re also needing to enhance the data with geographic-specific information (for reporting purposes). This information isn’t known by either the callers, or by the contact centre agents (for those who are curious, it’s the unique property reference number, which is unique to every address in the UK).

Thankfully, we’ve been given a source from the client which we can look this up against. In essence, we pass a postcode to it, and values are returned (in a JSON format). This includes the data that we’re looking for. Brilliant, so far.

When we got to thinking about things, there are several ways in which we could implement this:

  • Capture the data as we are already doing, & use Power Automate to get the relevant additional information

or

  • Automate this within the canvas app itself, and even give the customer service agents a bespoke address picker!

Deciding to go with the second option (it was a no-brainer, really), we moved ahead with this. We had the details that we needed in order to hit the address lookup API. One of the developers on the team created the Custom Connector, and got it working. We tested it out, and amazingly we got information back!

The next step was to see how we could do this within the canvas app itself. Now I’m going to admit here that although I’ve HEARD great things about Collections, I had never used them myself. In fact not only had I NOT used them before, I had NO idea how they worked! That was to change VERY quickly though…

Within a few hours, I had learned enough about collections to get how they worked, and pull data into them. It was actually really simple – I used the ClearCollect command to create a collection that was fed by the API query, which then created the data into a collection table for me to use. I was very impressed!

The code to return the postcode data. We had to do some manipulation due to the API constraints

OK – so I had my data in the collection now:

What were my next steps? Well, I was wanting to achieve the following:

  • Give the customer service agents an ‘address picker’ to use. They’d enter the customer postcode, & then be presented with a list of addresses that they could pick the correct one from
  • Automatically populate the customer address fields on the form from the selected address

Well, the first item (the ‘address picker’) was simple enough. Using a dropdown field, I pointed it at the collection data. This worked great, but the dropdown was only allowing me to select a single column from the collection to display. This meant that I could only select ONE column of data to return:

I can only select a single column!

1 column from the collection. OK, I thought – should be simple enough to handle. Let’s go and concatenate column values in the dropdown, to present the interface I’m looking for:

Now that’s more like it! Much easier for the customer service agents to use. OK – onto the next stage. Let’s go & set the fields to point to the collection, match to the value that’s selected in the dropdown, and populate. Should be simple to do, right?

Well…um, no, it’s not simple to do. In fact, it’s actually impossible to do. I was expecting to point to the dropdown selected value, & have the columns returned (from the collection). I could then select which column to use for a specific field. This, however, was not the case:

You have to love the ‘.’ (or ‘dot’) notation used in canvas app code. It shows you what values are available, and saves having to do lots of type. In this case, however, it also showed me that there was only ONE column of data to select from to display in the field. This was the ‘Result’ column.

This got me very confused. I tried going back to basics, and stripping out the concatenation in the dropdown. Wonderfully I was then presented with all of the different collection columns to use:

So let’s sum up things so far:

  • If I want to present the best option to the customer service agents (using concatenation), I can’t select different parts of the data for auto-population into fields
  • If I want to be able to auto-populate field values from the collection, I can’t use concatenation (& therefore can’t present user-friendly data to the customer service agents).

Note: Leaving aside wanting to show the house number & street, one of the main reason for wanting to concatenate was to handle buildings that had flats (aka apartments) in them. This is stored in a different column in the collection. It would therefore be difficult to show these both to the customer service agents

In essence, the behaviour of the dropdown field seemed to be that I couldn’t just change the displayed values without it ‘losing’ connection to the rest of the data. There was no ID that I could use to match on, or display what I wanted to.

This seemed to be a massive Catch-22. I tried various things, but couldn’t see a way out of this. I started to try to create a second collection, & concatenate fields from the first collection. This seemed like a good idea, though (with being totally new to it), I got lost. I tried various things; I even ended up managing to collect the entire data from the collection into a new column for EACH ROW!!

Thankfully, the community helped me out, in the forms of Peter Bryant & Clarissa Gillingham (I had posted about my issues on Twitter – the hashtag #poweraddicts is really great!).

With the help provided, I managed to work out the CORRECT syntax to use for the ‘AddColumns’ command. This now being in hand, I was successfully able to create a second collection & add concatenated field values to it:

Now for the moments of truth. Would the dropdown show this new column, & could I point the form fields to auto-populate specific columns?

Anticipation is the way to keep consumers coming back for more
Not me, but exactly how I was feeling!

The answer….was YES! It was working! I felt SO relieved. Let’s take a peek:

This was brilliant! We’re also populating other data in the background, but that doesn’t need to be visible to the customer service agents.

So in summary, I learned about collections, & how to use them. I also learned about the limitations of dropdown controls (when referencing them from other places), but came up with a way around it. Finally I achieved the result that I was aiming for. Very pleasing all round!

Have you come across something like this in an implementation? How did you manage to handle it (if you did)? Drop a comment below – I’d love to hear all about it!

MB-400 Power Apps & Dynamics 365 Developer Exam

I haven’t usually been putting up posts around the exams that I take. A few months back I did decide to write one on the MB-600 exam (MB-600 Solution Architect Exam), which just took off! It was quite amazing (& pleasing) how many people were looking at it, & asking me questions around the exam.

As a result, I’ve decided to continue this, and am therefore now writing this post on the MB-400 exam.

There are several different ‘ranges’ of exams within the Dynamics 365/Power Platform space. These are aimed at different types of roles, or specific specialisation/s within a role. A good example of this is the MB-2xx range. It covers functional technology, and is split across the different ‘main’ areas of Dynamics 365.

The MB-400 (the only one in the range at the moment) is aimed at developers. According to the official description for the exam:

Candidates for this exam are Developers who work with Microsoft Power Apps model-driven apps in Dynamics 365 to design, develop, secure, and extend a Dynamics 365 implementation. Candidates implement components of a solution that include application enhancements, custom user experience, system integrations, data conversions, custom process automation, and custom visualizations.

Candidates must have strong applied knowledge of Power Apps model-driven apps in Dynamics 365, including in-depth understanding of customization, configuration, integration, and extensibility, as well as boundaries and constraints. Candidates should have a basic understanding of DevOps practices for Power Apps model-driven apps in Dynamics 365. Candidates must expose, store, and report on data.

Candidates should have development experience that includes JavaScript, TypeScript, C#, HTML, .NET, Microsoft Azure, Office 365, RESTful Web Services, ASP.NET, and Power BI.

As anyone who knows me will attest, I am NOT a developer. However I decided (for several reasons) to give this one a go, and see what would happen! I knew I’d be pushing myself out of my comfort zone, there would be things I wouldn’t understand/know at ALL, but hey – I was curious to see what would happen! Even more challenging, I decided to book & take it within a 24 hour period!

Now as this has been out for a little while (& isn’t in Beta), there’s thankfully some good resources on Microsoft Learn about it. Take a look at https://docs.microsoft.com/en-us/learn/certifications/exams/mb-400, where there are several learning paths that can be followed.

A big shout out as well to Julian Sharp & Joe Griffin who recently ran a multi-week course around it. The official Microsoft learning paths are great of course, but seem to miss out quite a bit of what’s actually needed to be known for this. The course that they ran covered a lot more. Hopefully there will be more courses like this run in the future!

When passing it (& assuming that you’ve passed the MB-200 as well), you get a lovely shiny badge!

Microsoft Certified: Power Apps + Dynamics 365 Developer Associate
I’m SO proud of this!

Once again, I sat the exam through the proctored option (ie from home). The experience went somewhat better than previous times. Amusingly I got told off by the proctor during the exam for ‘looking down at the keyboard’, rather than looking at the screen! I explained that I was using a different computer, & kept clicking the wrong mouse button on it (leaving aside that I was exhausted when doing it!).

So, as before, it’s not permitted to share any of the exam questions. This is in the rules/acceptance for taking the exam. I’ve therefore put an overview of the sorts of questions that came up during my exam. (Note: exams are composed from question banks, so there could be many things that weren’t included in my exam, but could be included for someone else!).

  • Model driven apps:
    • User experience
    • Show/hide fields
    • Change field labels
  • Canvas apps – functionality, online/offline capabilities, field types (including searching/filtering data)
  • Plugin debugging
  • Configuring security for system connections (security types)
  • D365 Web API – how it’s used, types of calls made from/to it
  • Azure API – making calls to/from it
  • Code for importing data (debugging, variables)
  • Advanced Find
  • Types of calls (synchronous, asynchronous, )
  • Data modelling
  • Creating & deploying solutions through different methods
  • Publisher versioning
  • Identifying code variables, and saying what would happen in given scenarios
  • Power Apps Component Framework (PCF) – how to use, how to package components, how to deploy
  • PCF components & classes
  • JavaScript – code examples, what happens when a given scenario happens
  • JavaScript functions
  • Dynamics 365 Ribbon – what it is, what you can do with it, different types of functionality & ways to do things with it
  • Security & Permissions, including roles, teams, field level security, business units
  • Workflows, Power Automate Flows (how they’re set up, different functionality within them, how to do things with them given a specific scenario)
  • Business Rules (what they can/can’t do, different scopes, etc)
  • Field types (eg option-sets, calculated fields, roll-up fields, multi-select, etc)
  • Importing solutions – requirements for this, versioning, deployment between environments
  • Compatibility with Microsoft Teams

Now many of these (as I said above) are outside of my comfort zone. In fact, I’d say that even with absolutely cramming for a whole day for the exam, I still felt that I was guessing the answer for at least 30% of the questions. Admittedly though, as Julian Sharp says, a ‘gut feeling’ answer is usually right most of the time, coming from what the subconscious has absorbed during revision.

I was REALLY happy that I got a passing mark for this, & admittedly was VERY relieved as well. So now another lovely shiny badge in my collection, and I’m now going to go and update it on LinkedIn as well!

If you have any questions on this, feel free to drop them below, and I’ll try to help out as best as I can!

Canvas Apps, Patch command, & Business Rules

Recently I’ve been doing a LOT of work with canvas apps. As I think I’ve mentioned before (at least once or twice!) my background is the traditional ‘model’ style app. As a result, it’s been quite a steep curve to skill up, but I think I’m handling it alright. I’m (slowly) getting used to the way that canvas apps work, the ability to put different controls on the screens, and reference each other.

Heck, I’m even starting to play with more advanced navigation concepts, based on some REALLY great ideas that I’ve seen (Clarissa, I can’t say how grateful I am to you for all of your assistance & guidance!).

Gradient Adventure

Amongst all of this incredible & wonderous journey, I’ve also been learning some code. Yup – you heard me correctly! I’ve always said that I’m not a developer – I respect them greatly, but I don’t develop code.

True, I’ve picked up some SQL here & there, and will freely admit that running SQL queries against the Dynamics 365 database is SO much more powerful than running an Advanced Find. Of course, it’s necessary to know the joins, conditions & such. Redgate’s SQL Helper has been amazing along the way. With moving to cloud systems, things got a little more….complicated. XrmToolBox has the SQL4CDS tool which I’ve used several times, but I was really excited by the recent announcement/release of being able to (properly) run SQL commands against the CDS database from SQL Management Studio….

Anyhow, I’m digressing. So, I’ve been needing to learn canvas app style code. It’s like Excel commands, though (slightly) different at times. Things don’t always make sense (to me, at least) – I STILL haven’t figured out why some expressions need to be in a certain order. After all, according to mathematical principles it doesn’t matter if you write A>B, or B<A. Going to still need to wrap my mind around all of this.

So, one of the commands that I’m using quite frequently is the Patch command. If you’re really interested, you can check this out in detail at https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/functions/function-patch.

In short, Patch allows you to set record values from places other than a form table to the data that you’re saving. It also allows you to save field values that aren’t available on the canvas form table (due to limitations). I’ve referred to this previously at https://thecrm.ninja/canvas-app-record-set-regarding-field/. The scenario that I talk about there is just one of the things that can be done in this way. Since that post, we’ve come a long way, and are doing most things with Patch statements (due to the scenario requirements).

So that’s all well & good. However, there IS actually a reason for me writing this blog post….crazy, right? And it’s not to waffle on and on about patch statements. It’s about a very specific scenario that we hadn’t come across to date, but that came up last week.

Now, obviously you’re now VERY interested in hearing all about it, and learning for your own situations. I mean, otherwise you wouldn’t have stuck with me through this article for so long. So, let me set out what happened.

As mentioned above, we’re mostly using patch statements throughout this specific app. That’s….quite a lot of patch statements (especially as we also have IF statements governing which one is being used, as it’s not possible to use IF inside a patch statement, but I’m digress…). I’d say we’re pretty familiar with this now.

However, even with being familiar with it, we suddenly had a problem. One of the forms that we’re saving down started to NOT save down. Records weren’t being saved, which obviously is a problem!

Bear in mind here that we hadn’t touched the code for this specific action for a few weeks. Nothing had changed in our code, and nothing had changed from a platform perspective (ie Microsoft hadn’t changed any of the underlying functionality.

Going into the statement, we immediately started testing it out, and saw something interesting. We were getting an error that a required field could not be NULL:

This was quite puzzling – although in a model app we can set fields as required, and users can’t save the record until they populate it, this isn’t true in a canvas app (well, when using Patch, at least). See, it’s technically possible to use a Patch statement to create/update a record, but you don’t have to pass in required field (values). It’s a sort of workaround (& can be used in some scenarios for benefit, actually). So this happening all of a sudden was quite strange to us.

It was even stranger as we hadn’t been using the field on the form at all. The field that was being referred to was being used for a totally different process, in a different team, & not surfaced into the canvas app at all. This really was causing us to scratch our heads, and try to think (more) out of the box. It didn’t seem to be the code (we could set a value in code, but didn’t want to as it wasn’t relevant), yet we weren’t able to ignore it. Really frustrating!

With all of this in mind, I decided to go back to absolute basics after a few hours of troubleshooting. The field that seemed to be causing all of these issues was a relatively new addition, so I checked all of the details around it:

  • Was the field type correct for what it should be? Yes
  • Was it set as required on the CDS field definition? No (not that I thought this would help, but still checked)
  • Was the field on the entity form? Yes
  • Was the field set as required on the entity form? No (again, I didn’t think I’d get any joy from this)
    • Hold on….on the form designer it’s not set as Required. But when I open the form, and put some values in, suddenly it IS required.

Aha! OK – I’m now starting to see some light shining on this. I headed over to Business Rules to check out what might be there. Lo & behold, there was a business rule that set the field as required (when certain conditions were filled). An example of this would be:

Now this field hadn’t been in place when the code was developed (as mentioned above) – it had come in since. I was very curious if a Business Rule could require canvas apps to set the value, and so did some testing.

Disabling the business rule removed the error from the patch statement. Re-enabling it caused the issue again. OK – so we’ve found what’s been causing this, and could put in an adequate solution to handle it.

So in short, if you’re setting a field as being required through a Business Rule, you’re going to need to address it in any canvas app as well (that’s saving data down to the same form that it’s appearing on). Why it actually happens, when just setting it as Required on the form doesn’t, I have NO idea.

But it’s a good concept to keep in the back of your mind, I believe. Especially if there are multiple people working on developing a single entity, as otherwise you could find yourself in exactly the same scenario that we did!

Have you come across anything like this, or a different piece of strange behaviour? Comment below – I’d love to hear about i!

Power Automate & Lookup Fields

Recently I’ve been expanding my knowledge of Power Automate, and how it works. It really is a truly amazing tool, though there can be some quirks to things! There are so many connectors to use, though I haven’t really used that many of them to date.

Truthfully, most of my work in Power Automate is around CDS & Office 365. Occasionally I’ll dip into another system, but for the most part that keeps me busy enough. It’s not to say I don’t want to explore further, but finding the time can be quite difficult!

One of the great abilities that Power Automate has is to be able to update a record. With focusing on CDS entities for the moment, we would use the inbuilt action for this:

We’d run a query to get a specific record – this would give us the record ID (or GUID, depending on your preference). With this, we’d use the Update Record action & pass in the record GUID. After all, we need to know which record we’re going to update! So for example:

What we can then do is set values for the record. So we can pass in Dynamics Content, use Expressions, etc. These can be from records that are part of our Power Automate query chain, or from elsewhere.

For example, I can say that when a contact’s postcode changes (or zip code for USA), go away, look up the new city, and update it (Note: I haven’t shown the postcode lookup part below):

So this is all really brilliant. Different fields have different behaviours, of course, and we need to respect that. Otherwise the Power Automate flow won’t run, and will error. This is, of course, the digital equivalent of not trying to force a square brick into a round hole!

What we can also do is clear a field value. If for example we’re wanting to remove a value from a field, we can use the NULL expression on the field. When the Power Automate flow runs, it’ll clear whichever value the field is currently holding:

Now, one of the the field types available within CDS is the lookup field. I’m not going to go into what this is, as we should already know this!. We can, of course, set lookup fields values to populate the field, which works as expected.

However (& thanks for bearing with me so far), what happens if we want to clear a lookup field value?

Say for example that we have a task, that’s assigned out to someone. If they reject the task, we want to be able to remove them from the task record. We wouldn’t delete the task, as we still need it (& now would need to assign it to someone else). We need a way to do this.

I can hear what you’re thinking right now – mentioned above is the use of NULL, so we’d use this! Um…well, you’d think so. You can try that, but we’ve found that doesn’t always work. Additionally, that doesn’t actually seem to remove the underlying relationship that’s been put in place.

Update: Thanks to Lin Zaw Winn, who dropped me a line to let me know further information around this. The standard CDS connector (the first one that was available) allowed this to work, but the updated CDS connector (Current Environment) doesn’t allow it. Unfortunately the different connectors aren’t at parity, which is a pity!

So, there’s another way to clear lookup field values. This involves the Unrelate action that’s also available. The steps for this are as follows:

  1. Get the related record (lookup the record type, pass in the GUID for it)
  2. Use the Unrelate action to remove the connection

This will then remove the relationship, which actually results in clearing the lookup field value. In practise (for our scenario), this would look like:

Let’s take a bit of a further look at the options available here:

  • The Relationship field is the relationship between the two entities (eg here it’s Contact & Task). Thankfully you don’t need to manually type this – it’s easily selected from a dropdown list.
  • The URL field is the linked record itself

Note: It’s VERY important to have the Entity Name & URL values in the right order. I’d suggest looking up the connected record first (ie what the lookup field is pointing to), and using that as the Entity Name value. You’d then select the record where the lookup is saved on as the URL value.

What I’d usually suggest as best practise is to have a condition before this takes place. As mentioned earlier, removing the lookup would happen on a record update. This is because you wouldn’t be removing a field value if you’re creating the record!

But you’re not always going to want it removed. In the scenario that I’ve been dealing with, we’re only wanting to remove the volunteer if they’ve rejected the assigned task. So our Power Automate flow is set out like this:

  • When Task record is updated
    • Filtering on the field for ‘Task Accepted’, as we could have other things being updated on the Task record that we don’t want to trigger this particular process
  • Condition to check the ‘Task Accepted’ field value
    • When it’s something other than ‘Rejected’, cancel the flow
    • When it’s ‘Rejected’, run the Unrelate process set out above, and stop flow

You can obviously build out other functionality within it as you so desire.

So with this in mind, how do you think you could benefit from this? Drop a comment below – I’d love to hear!

My past year, & Alison Mulligan

This post is going to be somewhat different & out of the norm for the usual sort of topics that I talk about. It’s also going to be somewhat personal, and mention a special person who’s been an absolute rock for me.

So, where to start? Well, there’s been a lot that’s happened in my life over the last year or so. I touched on things briefly in my post at the end of last year. Several deaths in the family (father & grandmother), some sicknesses, etc. I’ve also started one job, decide it wasn’t right for me after almost a year, and then needed to look for another job. Thankfully I managed (even with all the craziness going on in the world currently), which I started in March 2020.

We’ve also expanded our own family (again), and been dealing with all of the usual things that come with children etc.

Now, why am I mentioning all of this, and specifically, why am I mentioning it now? Well, there’s one specific reason for me doing so, and that’s to mention Alison Mulligan. Otherwise there wouldn’t really be any point in this post at all, in my opinion…

Now, for those who don’t know Alison, let me try to summarise her as best as I can in a few words.

Created by LittleArtistRo at ScottishSummit ’20

Well, to start off with Alison works in the recruitment industry. Woah…hold on. Yes, she’s a recruiter. But she’s the FIRST recruiter that I’ve come across in over a decade who has what I would consider to be proper (& correct) principles. Now I’ve dealt with many recruiters & recruitment companies over my professional career. Some are better, some are worse, and some are truly dreadful (no, I’m NOT going to mention who they are).

However, Alison absolutely & totally bucks the trend. This isn’t just my opinion, it’s the opinion of everyone who I’ve met who’s ever known Alison. See, Alison doesn’t just want to fill roles with people. Her purpose (which she’s said time & time again, in private as well as public), is to find the right role for someone. That doesn’t stop at roles that she has to offer though. For her, it’s not about the money side of things; it’s about the person being happy & fulfilled in the role that’s right for THEM. To this end, she’ll connect someone who’s looking for a job with OTHER recruiters, or people within the industry who are looking to fill a role, even if she doesn’t make anything off of it.

I started The Oops Factor series last year. I had been bouncing ideas & concepts off several people, Alison being one of them. She was highly supportive of the project, and told me that I had to have her on as one of my first guests (which of course I did!)

When I was looking for my next role at the end of 2019/beginning of 2020, she was there at the end of a phone (and occasionally in person, when possible), whenever I needed to talk. She updated me constantly on the state of the market, & opportunities that she had, as well as those that she was aware of that OTHERS had. She was there as an absolute rock, without asking for anything specific in return. When I needed a laptop to present at PowerPlatform UG London in November 2019, and I didn’t have one available, she told me to come along to her office. When I got there, she handed me one of the office ones, told me to set it up as I needed, and to use it for as long as I needed to. How many people do you know who’d do that?

When I landed a new role (which incidentally wasn’t through her), she called me up immediately to congratulate me, and spent time on the phone asking about it, how I was feeling, etc. She truly cared about what I had been going through, and was happy & celebrating with me the success in finding something.

Now that was my own personal experience, but I know that it’s not unique to me. I’m aware of others who she’s helped in the same way, and who she’s continuing to help in these critical times. I constantly recommend Alison as the first point of contact to anyone who’s going to be looking for a new role – she’s that amazing.

Things don’t stop there though. Oh no. See, Alison is also active within the (technical) community. She comes along to the User Group sessions, knows the technology, & participates. She doesn’t even just confine herself to ones that are local to her – she goes to others that aren’t as near. As a result, people know her, and get to see that she’s not just pretending in order to get clients. She loves the technology that we all love, and can hold her own (usually) in conversations!

So for most people, that would usually be enough. They’re participating, getting known within the community, etc. Alison doesn’t just do that. She also gets involved in organising & hosting.

Let me give an example of this, to provide some some context. There was a SUPER special community Lego hackathon earlier this year.

The location for it had issues at the last moment, and it was going to be cancelled. Alison heard about this, told the organisers to leave it with her for a few hours, and she’d call them back.

Within that time, she organised to host it in her office building (remember – this is at the last minute, and not an easy thing to do!). She helped get things ready, participated throughout the day, helped pack things up, and finally joined everyone for the ‘after-event’ drinks. It’s not the first time that she’s done this, and highly unlikely to be the last.

Most people who are involved in recruitment tend to be looked at cautiously (at best) by the community. Honestly, we’re tired of them turning up, trying to get people’s details, and/or entice them away from current jobs without really considering what’s best for them. It’s happened time & time again, and we don’t like it. In fact, there was an offer last year from a recruitment firm to host a community event, and it was turned down due to this.

Alison doesn’t fall into this; she’s trusted (and absolutely adored, if you want the truth) by the community. Events without her there aren’t the same , though we understand of course that it’s not always possible to commit the time/travel to attending (we all have times that this happens).

Some years ago, a community organisation that I was helping out with told me that in every community, there are one or two people without whom things wouldn’t function at all. They may not be prominent, may not be paid much (or even at all), but they’re the crucial cog & lynchpin. If they weren’t around, things would fall apart.

In my opinion, Alison is one of these crucial cogs & lynchpins. I really don’t know how the different London technical communities would manage without her input, advice & help. I consider myself blessed to know her, count her as a friend, and to chat about motorbikes whenever we’re able to!

If you don’t yet know Alison, I humbly suggest that you try to come along to one of these events (which are virtual at the moment, making it somewhat easier), and get to know her. Her Twitter is https://twitter.com/AMulligan365, and she’s on LinkedIn at https://www.linkedin.com/in/amulligan365/.

You’ll appreciate her sense of humour, her experience in life, and the joy that she also has with seeing how the technology works to make everything better.
