hell sap_bo,
it happens. In my current project my colleague is developin univrse nd reports against a set of tables where there is no data yet.
Manager want’s to have the structure/template ready and when data is ready reports should be populated.
My colleague’s solution: universe - made a connection , created objects and build the reports 
though there is no data. You can see the report with vertical tables with no information.
He is successfull convincing manager that data will be populated as soon as data is available in tables.
I hope this clears your question.

Look at the sticky topic [XI 3.0] New features in XI R3.0 (Titan) and keep in mind that XI R2 is … just kinda old 
And here New features in SAP BI 4.0.
