A Co. is imported material, at the time of payment they are debited/credited the exchange diff. in respective material a/c. When i told to them that according to AS-11 this diff. should be debited/credited to P&L a/c instead of Material a/c , but they said that purchase a/c is also a part of P&L a/c. So now tell to me that whether it should debit or credit in respective material a/c or in P&L a/c? Also they are doing same treatment with Sale.
