How can I use the performance traces or DAX Studio to figure out which field in the underlying semantic model I'm connecting to is causing this issue?

Hi @steeleman5000 

What operation were you doing when you encountered this error?

@Anonymous - I have a chained dataset which connects to multiple PowerBI Semantic Models, I added 2 new measures to one of the underlying Semantic Models so I hit the refresh button to refresh the underlying sources in order to bring in the two new measures.  I checked all the measures and column names to ensure they are not duplicates already in this chained dataset.  I'm simply looking for a way to easily identify which dimensions or measures would be throwing that error.
