OTBI results in errors saying "The specified criteria didn't result in any data

Summary: Error in OTBI report using the

Labor Distribution Cost Analysis Real Time subject area

I am using the Projects - Labor Distribution Cost Analysis Real Time subject area for creating my Report. I have assigned the user the Labor Distribution Accountant Role, and assigned all the BU's against that role to the user, but still I am getting the same error reported in the initial post. There is another user, for which the report is generating data, and that user is not even assigned the Labor Distribution Accountant role. Is there something else that I need to check for troubleshooting.
