I’ve run into a problem that reminded me that while X++ types and corresponding CLR types (such as str and System.String ) can often be user interchangeably, they aren’t the same. I was trying to convert a utcdatetime value to the standard “sortable…

I got an .xpo file from an older version of AX with some code of interest and because it had a few thousand lines, it wasn’t exactly easy to navigate. At least splitting it by object would make my life much easier. Fortunately I looked at the internet…

I’m not sure that everybody is aware that a single event handler method (in Dynamics 365 for Finance and Operations) can be decorated with several event handler attributes. For example, a common method can handle both inserts and updates. [ DataEventHandler…

Development VMs for Dynamics 365 for Finance and Operations come with a cross-reference database that doesn’t match the actual code and metadata. There are many annoying references to Microsoft’s own test models, which aren’t included and therefore such…

This blog post explains a problem that you can run into when using reference group controls with grouped data – and a solution for this problem. I have a table which stores references to workers. The field has HcmWorkerRecId data type, i.e. it stores…

Yesterday Michael Fruergaard Pontoppidan published a brief blog post New capability in X++ : The In operator . He mentioned that this feature went unnoticed by most, which is my case too. And I didn’t find anything even when I explicitly looked for more…

What I really miss in X++ is the ability to throw exception objects. If you throw an exception in X++, it’s just a number defining what kind of exception it is, which usually says just “Error” (Exception::Error). You also typically add a message to infolog…

You can use Dynamics 365 > Find labels… in Visual Studio to find D365FO labels, but its capabilities are quite limited. Sometimes a better option is searching through the underlying text files directly and you can easily automate it with Powershell.…

Dynamics 365 for Finance and Operations runs completely in “.NET”, which has some interesting implications. The runtime and tools working with it (such as Visual Studio) offer many new options that may be very useful. One of these options is the ability…

Sometimes you may want to generate a Word document from code in D365FO, which gives you much more control over the result than if you simply printed a report to Word. Here is a very brief example of how you can do it. Start with creating an X++ project…

You can easily send a D365FO report in email just by configuring print destination to Email and setting a few properties. You can do the same from code, where you can also set the body. You must create an instance of SrsReportEMailDataContract class…

A comment below my blog post  Printing reports from code in AX2012 asked me to provide an example for D365FO. Here is it. The code is virtually identical. Only writing a file to a shared folder doesn’t make a good sense in cloud, therefore I changed…

I’m safely back in Prague and I would like to thank everybody who attended Dynamics 365 Saturday in Johannesburg . There were so many of you! And I want to give special thanks to people who did all the work to make the event happen and those who cared…

I recently had to move a form to another package, because we decided to extract some functionality to its own independent package. I moved files, built both packages and everything looked fine, so I started making changes for a new requirement. But…

If you call OData services in AX 7 (Dynamics 365 for Finance and Operations), you typically get data in JSON format, like this: { "@odata.context":"https://myaxinstance.cloudax.dynamics.com/data/$metadata","value":[ { "name":"ElectronicPaymentTypes…

A few days ago I was getting latest changes from VSTS to an AX 7 development box when it failed on a certain (custom) .dll file, because Visual Studio wasn’t able to overwrite the file. I made sure that all AX services are down, but it made no difference…

I’ve recently run into a problem with Recurring Integrations Scheduler and I think I won’t be the only one, therefore I’m going to explain it here. The Recurring Integrations Scheduler (RIS) supports both the old recurring integrations API (enqueue/dequeue…

You may have heard about QuartzAX, an application for file-based integration with AX 7 (Dynamics 365 for Finance and Operations, Enterprise Edition). Microsoft announced at the last Technical conference that it would be released in a few days, but it…

If you’re familiar with SOAP web services, you likely know that they use Web Services Description Language (WSDL) to document what operations a service provide, what parameters they accept, what they return and so on. This information can be used to generate…

If you download AX integration samples from GitHub, you’ll see (in JsonConsoleApplication project) that you can call JSON-based custom services by code like this: var request = HttpWebRequest.Create(ClientConfiguration.Default.UriString + "api…

I’m getting a lot of questions along the lines of “how on earth can we integrate our on-premises systems with AX 7 running in cloud?”, therefore let me share some of my thoughts. The first important point to realize is that “to integrate” means many different…

The on-premises deployment option for AX 7 (Dynamics 365 for Finance and Operations, Enterprise Edition) was longed for by many and it’s finally there. You can learn more about it on On-premises deployment landing page .

This blog post isn’t directly about software development, because I’m going to look at a certain feature of Windows Server, but my primary motivation is still dealing with development and testing. When you want to set up AX 7 (Microsoft Dynamics 365 for…

In this blog post, I briefly recapitulate how to throw and catch exceptions in X++ and introduce a new way of handling CLR exceptions in AX 7. X++ exceptions When you want to throw an exception in X++, you typically do it by something like this: throw…

I see a lot of confusion regarding Microsoft Flow and Logic Apps, so let me very briefly explain what they are and when you should use them. First of all, you should realize that they’re very closely related. For example, this is the designer for Flow…
