Merge dimens

Hi,

  I have my below merged dimensions named as "Merged Dim" from 3 Bex and 1 Universe data providers  in my report.

Merged Dim

query 1

query 2

query 3

univ  1

Now Iam looking to display reports in one tab as Bex report and another tab as universe:

Tab 1:

Merge dimens(query1+query2+query3)     sales amt

Tab 2:

univ1                                                  sales amt

Iam struck here as i have already merged bex and universe. I want something like bex alone merged dimens and shown in tabs. Could you help in creating the Merge dimens (query1+query2+query3) ?

Thanks,

Dinya
