SQL 2022 mds issue

Hi Everyone,

 

Im having an issue whereby in mds we are unable to view attributes and we can add attributes. When i try add attributes it just loads no errors. I did restore a copy of mds database of a working database that mds was working and still experience the same issue.

    Hi, This looks very similar to a known issue affecting Master Data Services in recent SQL Server 2022 cumulative updates. Microsoft has officially acknowledged in the CU27 release notes (KB5104824) that certain MDS operations, including creating attributes, creating entities, and loading hierarchies in Explorer, may fail or not load correctly.

    Could you check which SQL Server 2022 build you're currently running? Please execute 

    SELECT @@VERSION

    If you're running CU26 or CU27, you may be experiencing this known issue.

    Microsoft is investigating a fix. There is also a related Microsoft Q&A thread reporting that CU26 breaks the MDS web application while leaving the database intact. This would explain why restoring a working MDS database didn't help.

    Official Microsoft documentation:

    https://support.microsoft.com/en-au/servicing/sql/sql-server-2022/cumulative-update/kb5104824-cu27 

    Related Microsoft Q&A discussion:

    https://learn.microsoft.com/en-us/answers/questions/5993516/master-data-services-web-app-renders-empty-after-s 

    I would recommend checking the installed build and opening a Microsoft support case before attempting any rollback or manual replacement of MDS application files.
