Dear Shilpa,
The SAP standard function doesn't save profit center into table BSID, BSAD, BSIK and BIAK. You can find it in table FAGLFLEXA by company code, fiscal year, document number, document item. You can also make a statement by T-code sqvi or sq01/sq02/sq03, and Data source select logical database,logical database select BRF.
Hope this will help you.
Regards,
Ian Wang.
