G/L Open Items and Cleared Items

Hi,

I Have posted one invoice on 10/02/2014 using FB50, Now the g/l open items are stored in BSIS Table.

After (05/04/2014) i have cleared the open item, now the value stored in BSAS Table. Now The Thing is now i want to check the report on back date

it means on 31/03/2014. Now where the value is stored?  (May be now the value is stored in BSAS Table only.)
