SSAS: The Sort Order Specified For Distinct Count Records Is Incorrect.

Symptoms

During a processing time of a cube that contains a distinct count measure, the process fails with the following error message:
The sort order specified for distinct count records is incorrect

Cause

This is most likely caused by different sort order used on the data warehouse data set and the analysis service database data set.

Resolution

Modify the sort order of the data warehouse data set so that it will match with the analysis service database data set.

Into the Depth 

Navigate to the analysis database and start to process the desired database. When the processing begins, the Process progress window will pop up. Wait till the process gets failed. After the process failed, find the failing measure group and expand to the last node where you can see an SQL query. Double click on the query and view the details. This query gives you the exact order by the column which caused you this trouble. 




Execute the query using the data warehouse database. View the analysis service database data set and compare the result. There will be a mismatch between two data sets.




May the force be with you!

ASP.NET Core 3.1 - Setting up React app with Typescript

With the release of .NET Core 3.1, I have decided to migrate one of my .NET core 2.1 solutions which contain ASP.NET core API project, React Web project (ASP.NET core project with react typescript template) and .NET Core Library project.  So I started the migration with the Library and API projects. Based on my experience, I think it was not a smooth migration due to the vast number of breaking changes but I managed to up and run both projects. Lastly, I have started to migrate the React ASP.NET core project. It was chaotic but I managed to up and run the project. Thought it worked I got some issues here and there so I decided not to continue with the same project rather create a new ASP.NET Core 3.1 React TypeScript template project.
