How to Resolve DVT Script Issues When Applying Quality Updates in LCS for D365FO

 Recently, while applying Quality updates 39, I encountered an error stating

 "DVT script for service mode: AOSService on machine."

Upon examining the error logs, I found the description: "ERROR: System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel."


After some research, I discovered a solution:

First: Abort the current process in the Lifecycle Services (LCS) as this option is only available for environments in the Deployed state. 

Second: Then, navigate to the Environment details page, click Maintain, and select Rotate secrets. Choose Rotate the SSL certificates and confirm the action. 





This simple solution resolved my problem.

Creating a class, the best practice way in D365F&O

 Some time ago, I shared my thoughts on the 'construct' pattern, which is commonly used in AX. While I often make use of it, it’s not without its flaws—it can actually violate some best practices. (I’ll cover the issue of deep class hierarchies resulting from this pattern in a future post.) First, it’s worth noting that you can customize the compiler level and the best practice checks it performs. To do this, compile something to bring up the compiler output window. Then, click the Setup button to adjust the settings. For this example, I used compiler level 4 and enabled all best practice checks. Now, let’s create a simple class. This class will simply display information from an InventTable record. 1. ClassDeclaration As we start designing this class, it quickly becomes clear that we need to declare an InventTable record as a member variable. /// <summary> /// Class written to test the construct and new... patterns /// </summary> /// <remarks> /// De...

How to remove deployed model in Tier2 environment in D365FO

 How to remove the deployed model in the Tier2 environment Dear all, I have an issue with the deployed model in the D365FO Tier 2 environment. I have some models in the development environment: Model A Model B Model C Model D I want to apply only Models A, B, and C for the Tier 2 environment. For the first time for deployment, I created a deploy package(including Model A, B, and C) in development and applied an update for the Tier 2 environment. However, yesterday, developer X on my team deployed a new deployment package(Model A, B, C, D). So today I could not deploy the package in Tier 2 with Models A, B, and C. Solutions: 1. Download the same package from the Asset Library that was previously deployed. Add File ModuleToRemove.txt (with model listed). Reupload to Asset Library and deploy to UAT. When I do this,  there's a warning on LCS that "it will first reinstall the model and then delete it. In order to not reinstall, delete the model from the package." 2. Create a n...
