Issue with J1IS to decrease cenvat payable
We have one requirement from our client. Client wants to post adjustment entries to the cenvat payable accounts incase of any increase/decrease of the same. In case of increase in cenvat payable, we can use the transaction J1IS and post the same and it is standard process only. In case of decrease in cenvat payable, we have created one subtransaction type and assigned the GLs against ETT OTHR with subtransaction type. Here the entry also posted correctly by debiting the cenvat payable and crediting the cenvat suspense account. But we are facing one problem in J2IUN utlization transatction. In both cases the payable amount is increasing only. Actually in decrease case the amount should decrease in J2IUN screen, but in system it is increasing. Due to this our customer is unable to do utilization. I have tried all the ways, by configuring J1IH transacation also, but it is not effecting payable amounts in J2IUN.
Please help on the same.
Thanks in advance.
