Use UI Flows in Power Automate to interact with a web site

UI Flows are new features from power platform april 2020 wave, and allow you to integrate local installed applications and web sites. I’ve made a video with UI Flow for web sites. In this demo I’ve create a flow that reads the Bitcoin / Euro rate from a web sites and sends it per Email.

Call an Azure Function from X++ in Dynamics 365 Finance / SCM

Create an Azure Function

Azure Functions are simple way to pack and provide business logic as web service without worrying about hosting a web server. Azure Functions can be implemented in different programming languages like C#, JavaScript, PHP, Java, etc. and can be hosted on Linux and Windows with different runtime environments that feed your need.

In the Azure Portal click + Create a resource and search for Function App:

Create a Azure Function App

In the next screen choose a subscription and create a resource group (or use an existing one if you like). Provide a useful name and choose code as Publish method. Select .NET Core 3.1 as runtime stack and a region that is near your location:

Configure the Azure Function App to use .NET Core 3.1

Click Review + Create to create the Azure Function. It takes a view minutes to provision all the required elements:

Deploy the Azure Function App

Click on Go to Resource. Next to the Functions group click + to create a new function and select In-Portal to edit the function code direct in the browser:

Create a new HTTP trigger

Choose the webhook + API to create a demo function that can be called via HTTP POST.

Use webhook for the Azure Function

This will create a function that takes a name as parameter and returns “Hello ” + the parameter name.

C# Azure Function code

You can test the function by using Test tab on the right. The function takes a JSON string with a name parameter and returns a simple string.

Test the Azure Function with a JSON string

Call the function from X++

In the azure portal get the function URL with a function key. Copy the URL with the key:

Copy the Azure Function URL with function key

In Visual Studio create an X++ class with a main method for testing. Use the System.Net.Http.HttpClient class to call the service. The content is a JSON string encoded in UTF-8 with a name parameter and value. In this example the name is Dynamics:

System.Net.Http.HttpClient httpClient = new System.Net.Http.HttpClient();
System.Net.Http.HttpContent content = new System.Net.Http.StringContent(
        "{\"name\":\"Dynamics\"}",
        System.Text.Encoding::UTF8,
        "application/json");

At the moment X++ does not support the await keyword for asynchronouse calls. The workaround is to use the Task.Wait() method. Call the service with your function URL async and get the content of the call:

var task = httpClient.PostAsync("https://<YOUR_FUNCTION_URL>",content);
task.Wait();
System.Net.Http.HttpResponseMessage msg = task.Result;

System.Net.Http.HttpContent ct = msg.Content;
var result = ct.ReadAsStringAsync();
result.Wait();
System.String s = result.Result;

info(s);

Start the class from Visual Studio. The result should look like this:

Call the Azure Function from Dynamics 365 Finance

Connect to the SQL database of a Dynamics 365 Finance Test instance

In Dynamics 365 Finance / SCM we can no longer access the SQL database of the production environment directly. However, we can access the SQL database of the Acceptance Test instance. All required information can be found in LCS. I’ve made a video where to find this information in LCS and how to connecto to the SQL database.

Using SQL DDL Triggers to restore read Permissions programatically after Dynamics AX 2009 Synchronization

Recently, a customer using Dynamics AX 2009 implemeted a web service that access a view directly in SQL Server. Therefore they created a new SQL user login and gave the user read permissions on the view.

Read permission on a view

However, when synchronizing the data dictionary in Dynamics AX 2009, the views are droped and recreated and the permission on the object is lost. Therfore the webservice call fails.

One way to address this issue from a SQL perspective is to create a DDL trigger that sets the permissions on the view programmatically. Here is a small SQL script that sets read permissions for the user view_user on the the DIRPARTYVIEW after the view has been created again.

CREATE TRIGGER [VIEW_PERMISSION] 
ON DATABASE 
    FOR CREATE_VIEW
AS 
BEGIN
    DECLARE @name SYSNAME
    SELECT  @name = EVENTDATA().value('(/EVENT_INSTANCE/ObjectName)[1]','SYSNAME')

    if @name = 'DIRPARTYVIEW' begin
        GRANT SELECT ON [dbo].[DIRPARTYVIEW] TO [view_user]
    end
END
GO

ENABLE TRIGGER [VIEW_PERMISSION] ON DATABASE
GO

Dynamics 365 FO: Export Entity Store to Azure Data Lake

Since version 10 Dynamics 365 for Finance and Operations supports the entity store export to Azure data lake. The main benefits are reduced costs because Azure Cloud storage is cheap and easy access for Business Intelligence tools like PowerBI.

If you are running a local development VM, the data connection tab in system parameters ist deactived by default. However, this can be actived using the SysFlighting table.

The configuration is pretty well documented by Microsoft. I’ve performed all the necessary steps and recorded a video:

Connect Azure Data Lake Storage with PowerBI dataflow

PowerBI dataflow performs ETL (Extract Transform Load) workloads in the cloud. PowerBI Pro and Premium Users get dataflow storage without additional charges. However, this storage is managed by PowerBI and you cannot access it directly. Therefor BYOSA (Bring Your Own Storage Account) is support to connect you own Azure storage account with PowerBI dataflow. I’ve made a video, following the documentation, how to connect an Azure storage account with PowerBI. Please find my video youtube:

I’ve created a video tutorial how to configure PowerBI on a stand alone Dynamics 365 Finance and Operations developer VM

Setup multiple developer VMs for Version Control with Team Services in Dynamics 365 for Finance and Operations

Here is a walkthrough how to connect two Dynamics 365 Finance and Operations developer VMs with VSTS.

Configure Azure AD and setup Visual Studio Team Services

Before you start, you have to add your developers to Azure Active Directory. If you have Azure AD Connect make sure the accounts have been synced to the Cloud. In my case I added two additional users to my Azure AD.

Configure Developer Accounts in Azure AD

Next logon to your Azure Portal using your Organization Account. Create a new service and search for “Team Services”. You should find Visual Studio Team Services (preview).

Create Visual Studio Team Services project in Azure Portal

Create a new instance of VSTS. The basic version of VSTS for 5 users is free. Make sure to use Team Foundation Server as Version Control system. You may choose any Methodology you like, but II ‘d recommend to go for CMMI compatible one.

Create Visual Studio Team Services project in Azure Portal

After the deployment succeeded, logon to your Visual Studio Team Services account, using  the URL https://<ACCOUNTNAME&gt;.visualstudio.com . There you see a new project. Open the project and add your developer users by clicking the (+) icon on the upper left “Members” pane. If everything is configured correctly, you should be able to add your AD users. In my example developer one and developer two.

Add developer accounts to Dynamics 365 FO project

Configure Developer VMs

If you are using the VHD Images from Microsoft, the first thing you should do is to rename the computer. If you don’t rename the VMs you will get errors when mapping the source control on multiple machines. In my case I rename the VMs to “devbox1” and “devbox2”. No domain is needed. Details here.

Rename Dynamics 365 FO developer VM

Configure first Developer Box

After the VM reboots, open Visual Studio 2015 in Admin mode. Depending on your licensing you may need to provide additional credentials to use your subscription. Don’t get confused if this may be your Microsoft ID (aka. Live ID) while you need your Organization Account to access VSTS. Zwinkerndes Smiley  From the menu bar select > Team > Manage Connections. Provide the URL for your VSTS account.

Connect to Visual Studio Team Services

After you have connected to VSTS select the project to work on. Next, from the Team Explorer open the Source Control explorer. Map the root folder to a folder on your developer VM.

Map Source Control Folder in Visual Studio

Afterwards use the source control explorer to create two new folders. One for Visual Studio Projects and one for metadata. This is where the D365 source code artifacts will be stored. Check in you pending changes. This will sync the folders to VSTS.

Map Dynamics 365 FO metadata folder

Now, in the Source Control Explorer open the dropdown Workspace and edit your workspace. Map the metadata folder to C:\AOSService\PackagesLocalDirectory.

Map Dynamics 365 FO metadata folder

From the menu bar > Dynamics 365 > Model Management > Create a new model. Give it a name and complete the wizard. This will ask you to create a new Dynamics X++ project.

Create new Dynamics 365 FO project

In the solution explorer, right click on the project and add to source control.

Check in to Source Control

Add a new element to the project, for example add a new String Extended Datatype called DMOCustomerName. In the solution explorer, right click the project and select build. After a few seconds you should see the console output “Build completed”. Check in all your pending changes.

Next, from the Team Explorer open the Source Control Explorer. You should see the model structure in the tree view. Right click on the metadata folder and select “Add items to folder”. Navigate to your model folder and there to the Descriptor folder. Add the Model Descriptor XML file. Unfortunately you have to do this manually, otherwise the second developer can sync the Folders and Extended Datatypes etc. but will not see the model in the AOT.

Add Dynamics 365 FO Model Descriptor File to Source Control

You can also inspect your code in VSTS

Dynamics 365 FO X++ Source Code

Configure second Developer Box

Make sure that the second VM is properly renamed. Open Visual Studio in Admin mode and connect to VSTS. Logon with the account of the second developer. Select the Dynamics 365 project and again in the Source Control Explorer map the metadata folder to C:\AOSService\ PackagesLocalDirectory. Checkout the latest version of the metadata folder.

Get Latest Version from metadata folder

This will create the model folder in the packages directory.

Model folder created in PackagesLocalDirectory

In Visual Studio open the Dynamics 365 Application Explorer. If the AOT is in classic mode, right click and switch to model view. Scroll down and you we will see the synchronized model and the its software artifacts.

Inplace Upgrade of Windows Server 2012 HyperV to 2016

There is no upgrade path for Windows Server 2012 (non-R2) HyperV role to Windows Server 2016 HyperV. The easiest way would be to setup a new Windows Server 2016 and activate HyperV. However, there may be reasons to perform an inplace upgrade. This is an experience report doing so

Prepare for the Upgrade

First make sure there are no virtual machine related files left on C: drive. Move the configuration files and especially the virtual hard disk files to another drive. I recommend to make list where the VHDX files are place. This can easily be done via PowerShell

Get-VM –VMName * | Select-Object VMid | Get-VHD | select Path | ft

Next uninstall the HyperV role using the Server Manager. Simply select remove roles and features and select the HyperV role. This step requires a reboot and your server will come up a simple plain windows 2012 server.

After HyperV was uninstalled make sure to remove NIC teaming in case you are using this feature. I recommend to deactivate all but one network adapter. This can also be done using the Server Manager.

Perform Inplace Upgrade

Insert a disk or mount the Windows Server 2016 image. Start the upgrade process. When asked choose to keep all your data and apps. This will preserve your data and applications e.g. the RAID Manager software. The setup wizard warns you that an inplace upgrade is not the preferred way to setup server 2016. Accept and proceed. The upgrade will take a while and requires some reboots.

image

Setup HyperV on Server 2016

After the upgrade process has finished, its time to setup HyperV again. First configure the NIC teaming again. Activating the HyperV role in Server 2016 is almost the same as in Server 2012. This can be done by using the Server Manager installing new roles and features. Activating HyperV will require a reboot. After the reboot configure a virtual switch so your VMs can access the network again.

Import the Virtual Machines again

By default HyperV on Server 2012 has no clue about the VMs in former Server 2012. The virtual machines have to be imported manually. This can be done using the HyperV console. First, provide the folder where the virtual machine configuration is placed. Afterwards choose to directly register the VM.

image

Next provide the folder where the virtual hard disk files are placed. Don’t get confused because you don’t see the actual VHDX files in the selection dialog. The import wizard will check if the virtual hard disk named in the configuration file can be found in this folder. If the wizard can’t find the virtual hard disk file, take a look a the list of vhdx file paths generated by the PowerShell script.

image

When all the VMs are imported the upgrade is almost finished. The the network connection of the virtual machines and make sure they can access the network via the newly created virtual switch. Removing the virtual network adapter and adding the virtual network adapter again can help Zwinkerndes Smiley  Perform some tests, maybe reboot the server again and install the latest updates.
