Hello,
This is what I understand.
You have one dimension(Dim1) which has a hierarchy x and its broken down as
Product group - Product line - Model.
In the bex report can you put the Dim1 (actual element like comp_code) and sign data in columns and activate the hierarchy on Dim1. (hierarchy tab in query designer)
you would get a display like this
Dim1(top node of hierarchy) Dim1(2nd node of the hierarchy)
Dim2 Signdata Signdata
Thanks
Ed.
