Measure changing when column added to matrix

AnthonyH28 Can you share the relationships between all tables involved please? Just to clarify,  'Sales Metrics'[Sales Combined YTD] is a column, correct? Please add that to the same visual with [Percent of Comany] (which is also a column, right? What table is it in?) and see if that helps you see what's going on a bit better, but yes it will be relationships between Sales Metrics and Percent of Company table. My guess is that Dim_Product to Percent of Company is 1 to many with single cross filter direction? This can't talk to/filter Sales Metrics.
