I'm having trouble trying to understand what the desired outcome is. Are you wanting to filter on a measure or a dimension? Would you be able to post a sample workbook?
Tracy, thanks for your response. I wanted to filter by two dimensions. The primary source would filter the primary measure, and the secondary source would filter the secondary measure (dimensions are not linked - nor are they supposed to be linked). I'm not able to post a sample workbook. But I did get my desired outcome by integrating both sources into one table in the underlying database.
