Priority-based throttling for Dynamics 365 integrations

Priority-based throttling for Dynamics 365 integrations 1

We’re finally getting a throttling functionality for OData integrations!

It’s one of the most common requirements from a customer: the need to integrate Dynamics 365 with other systems. With the (back in the day) new AX7 we got a new way of integrating using the OData REST endpoint and the exposed Data Entities.

But integrations using the OData endpoints have low performance and for high-volume integrations it’s better to use the Data management package REST API. A (not so) high volume usage of the OData REST API will translate into performance issues.

The throttling functionality is in preview starting version 10.0.13 which is currently in PEAP. It will be enforced starting April 2021. You can join the Data Management, Data Entities, OData and Integrations Yammer group for more info. Remember you need to join the Insider Program for Dynamics 365 first to be able to access the Yammer group.

If you want to learn more about OData and throttling you can check these resources:

Self-service & SSRS: print reports as PDF in your Dev VM

Self-service & SSRS: print reports as PDF in your Dev VM 2

If you’re working with the (not so) new self-service Tier 2 environments in Dynamics 365 for Finance and Operations you might have already noticed this: the reports in Tier 2+ and production environments aren’t using the SSRS report viewer, instead they’re being displayed in a beautiful PDF preview form.

But what happens on your development box?

If you want to know more about self-service environments you can read these posts I wrote a while back:

Add a Menu Item to a SysOperation dialog

Add a Menu Item to a SysOperation dialog 3

A short one! Some time ago I explained how to add a multi selection lookup to a SysOperation dialog and in this post I’ll explain how to add a Menu Item as a Function button to the SysOperation dialog.

Before the SysOperation Framework was introduced in AX2012, we used the RunBase Framework, and maybe doing these things looked easier/quickier with RunBase because all the logic was in a single class. But in the end what we need to do is practically the same but we have to do it in the UIBuilder class.

Let me show you and explain all the code. I’ll only show the DataContract and UIBuilder classes as they’re the only important ones in this case.

Creating (more) community, or trying

I’m sorry for my English-speaking readers because, maybe, this post will be a bit useless for you as all the content I’ll talk about is in Spanish. But it’s always good to know!

In the last few days I’ve taken part in a community event, the 365 Saturday online, and I’ve also started a podcast. I want to talk a bit about this.

Dynamics Power Spain Online 2020

This has been my fourth participation as a speaker in the last three years and as usual I’ve presented a session with Juanan. This time we’ve talked about using Azure DevOps with Microsoft Dynamics 365 for Finance and Operations.

It’s a topic I write about a lot, but we really think there’s still many people using it in a wrong way or just using the source control part. And that’s bad!

Azure hosted build for Dynamics 365 Finance & SCM

Azure hosted build pipeline

Behold #XppGroupies! The day we’ve been waiting for has come! The Azure hosted builds are in public preview with PU35!! We can now stop asking Joris when will this be available, because it already is! Check the docs!

I’ve been able to write this because, thanks to Antonio Gilabert, we’ve been testing this at Axazure for a few months with access to the private preview. And of course thanks to Joris for inviting us to the preview!

Azure hosted build
Riding the Azure Pipelines by Caza Pelusas

What does this mean? We no longer need a VM to run the build pipelines! Nah, we still need! If you’re running tests or synchronizing the DB as a part of your build pipeline you still need the VM. But we can move CI builds to the Azure hosted agent!

You can also read my full guide on MSDyn365FO & Azure DevOps ALM.

Remember this is a public preview. If you want to join the preview you first need to be part of the Dynamics 365 Insider Program where you can join the “Dynamics 365 for Finance and Operations Insider Community“. Once invited you should see a new LCS project called PEAP Assets, and inside its Asset Library you’ll find the nugets in the Nuget package section.

Compiler warnings: are you checking them in Dynamics 365?

Warning

Compiler warnings. Warnings. They’re not errors, only warnings. You can just overlook and forget them, right? Well, I hope you aren’t.

“But even the standard code done by Microsoft throws warnings!”, you could say. And that’s true, but that’s not your code, it’s Microsoft’s. If a functionality you’re using breaks because they didn’t care about their warnings, you can open a support request and it’s Microsoft’s job to fix it. If your code breaks some functionality because you didn’t care about a warning, it’s your job to fix it, and your customer will want it as fast as you’d want Microsoft to fix their error.

That’s why we should be warned about warnings (badum tss).

Messaging API: add actions to the message bar

Messaging API actions

With the latest Dynamics 365 for Finance and SCM 10.0.10 version, we’re getting a new feature that will allow us to add actions to the message bar, using the Messaging API like we used to do in AX2012 with the SysInfoAction class.

Remember this is in the latest preview version. You can access the preview versions joining the Dynamics 365 Insider Program.

Unzip a Stream in Dynamics 365 FnO

Since Microsoft Dynamics 365 for Finance & Operations is a cloud-based ERP we cannot work with files on the AOS drive anymore. It was pretty usual to have file-based integrations in AX where you got a file in a folder and processed it.

Of course it’s still possible to work with files, for example from a storage account on Azure like Miquel Vidal has shown in his blog (in Spanish) or with the Recurring Integrations Scheduler tool.

Unzip .NET Streams

Most of the functionalities that consist in uploading of downloading a file is MSDyn365FO use .NET Streams, usually its child class MemoryStream.

So, how do we unzip one of these files? For example, the ISO20022 vendor payment journal file is zipped. What if we need to access the XML file contained in the ZIP?

We’ll need to use the ZipArchive class from System.IO.Compression namespace, and it’s really really easy. For example:

Edit: this code is valid for a single file ZIP. If the zipped file contains more than one file you must process each Stream inside the while.

We need to copy the unzippedStream stream (which is a DeflateStream) to a MemoryStream (which must be initialized) before returning it.

Remember that to access a .NET collection we need to use an enumerator to loop through it. If you don’t see the methods in the lookup using dot notation just write them, writing .NET code in X++ is still a bit buggy…

Add multi selection lookup to a SysOperation Framework dialog

First 2020 post! Happy new year! Yes, I know it’s already past mid January…

When you add a field to a SysOperation Framework Data Contract the lookup that the framework creates (if the EDT has a lookup) is a simple, single select lookup. Let’s see how to create a multi select lookup in MSDyn365FO.

The SysOperation Framework and MVC

But first of all a bit of an introduction! The SysOperation Framework was introduced in Dynamics AX 2012 to replace the RunBase Framework, and is used to create processes that will be run by the batch server. The RunBase classes are still around in Dynamics 365 for Finance and Operations. Some standard processes still use it while others use it to later call a SysOperations Framework class.
