DATAMART (PREVIEW) CdsaMashupUserException
I have the following error message after giving Save in Power Query from the Datamart: Pd: The column Gross Sales exist.
For me, the exception was triggered by an extra space " " at the end of the column name. This originated from the column name manually created in an excel table.
This is confirmed by the fact that its does not prevent the ETL to run correctly in PowerBI or during the ETL phase but lead to the error when the model is being built.
The solution is to remove the blank in the column name either at source or in the ETL.
Hopes this will help the community
