We switched from a SQL server 2017 to a newer SQL server 2019. We deployed all our SSIS-packages in the same way to the newer server. Since then we have often the same error on processing-tasks like cube-processing or dimension-processing on the newer server:
Error: Trace: The Subscription identifier is invalid; it must be unique when subscribing and the identifier of a registerd subscription when unsubscribing.
So our jobs are failing. Some jobs are scheduled every ten minutes. They don't fail always, but sometimes within a day.
I changed our SSIS-package with SSAS-tasks from a projecttype of sql server 2017 to the projecttype of sql server 2019, but this didn't solve this problem. I have no clue what is wrong.
