If user is paying the invoice using the Payment check method, we can reverse the payment using Process manual check where user can select the check number and accordingly the voucher will get listed out. And then user can return that PO voucher and then PO voucher will become open for apply payment.

Hope this helps.

Hello!
There was an invoice incorrectly processed. The invoice will need to be reversed and reprocessed. When reversing the PO, how does the funds go back to the non material PO so that when the new invoice is processed there is fund son the PO for the correct invoice.

There is no such utility in MAS 500 that automatically refund the PO payment at the time of reversing the PO. If User already applied payment against PO invoice voucher then first they need to be pass separate entry for payment reversal entry against this PO invoice voucher by using “Process Manual Checks” menu option of AP module in MAS 500.

You may need to get this customised if you still want it to happen.

Thanks,
Dinesh
