Hi, I was trying to do an incremental update on one of the cube and got this error message "(TR1901 - There is a duplicated key-value. (Category Index) in .....".
Is the checkbox marked as "unique" in the property, and the data is not unique? If you don't know, you might want to check the latest data for duplicates by running an impromptu report against that specific that transformer told you it was.
