SEM-BCS (BW Reporting)

Hi All,

I would like to know how SEM-BCS stores data (balance values) in BW cube. If I have to generate a B/S report, how would I restrict the Key Figure to show balance as of the 2nd quarter? The issue is the ranging of the Posting Period. Is it (4 to 6) or 6(Last month of quarter) or (1 to 6)?

Thank.
