"Source table [table_name] already has an active transform map [Map_Name]"

[S A Martin]

I'm trying to create a Robust Transform Map for an existing data source.  When I add a Robust Import Set Transformer, I'm getting an error:

Source table [table_name] already has an active transform map [Map_Name]

The data source does have active transform maps, but I've never had a problem adding a robust transformer to other data sources with active transform maps.  I disabled the transform maps and tried again, but received the same error.  I'm not sure what I'm doing wrong. 

Any help would be greatly appreciated.

Getting same error, did you find fix for this issue?

• Navigate to All > System Import Sets >Administration > Data Sources and open the specific data source
• Look for any active transform maps under the related tab transforms; if there are any, set them to active: false

That was the solution I used, too.  After posting the original question, I realized I had missed one of the transform maps when setting them all to inactive.  It let me proceed normally after it was also deactivated.
