Refresh error: duplicative value
Hi, I am getting this error message when refresh in service. The duplicative value power bi shows is not even in my data and I know there are not duplicate values since I removed them in power query....
Hi PowerBI123456 , there were similar topics earlier, based on this link you should check relationships, it might happen that there were some relationships automatically created and should be removed.

You could also check relationship types (1:n, n:n...) and if there are any duplicates.
