How to use 2 different query objects in one query sap bo

Hi all

I am having a report having two queries.In those two Queries all objects are different.Now i am having a requirement to use the objects from both the queries(I.e Some objects from Query 1 & Some objects from Query 2).For this what should i do?.How can i get the both queries objects in one report?.Right now am using 4.0 Source file is excel.For this i have added a common dimension in both excel sheets and i uploaded it in to bo and i applied merge on common dimension.After applying merge on common dimension also am unable to use the objects from both the queries(tool was not allowing to drag the objects).

Can anybody please answer me to resolve this issue.

Thanks in Advance

Suresh.
