The union keeps it with one data source, but you should have more dimensions/measures to use within the list.
Thanks for the reply.
The records have doubled but no extra measures or dimensions.
Forgot to add that I am using V8 but I need to test in V7. I wouldn't have thought that would make a difference.
The [copy] dimension should be there.
Thanks very much - I need my eyes testing I didnt spot it.
