I'm also using Fields 1, 2, and 3 as Dimensions, and I really want to aggregate on Field 4, but get a seperate ranking for each of the other dimensions. This is working ok so far.
If I want to collapse a dimension in the pivot table, it messes everything up. I assume it's because I'm aggregating and ranking by each of the dimensions. Is there a way to be able to collapse a dimension, and keep an accurate ranking within the dimensions I have open?
