I created a Prepayment Request for 50% of a PO and processed the prepayment payment. After that, I received the goods, created an AP Bill for the same 50%, and applied the prepayment to the bill to close it.
Now I’m trying to create another PO Prepayment Request for the remaining 50% balance, but Acumatica shows $0.00 remaining and won’t let me request any additional prepayment. It looks like Acumatica is reducing the PO’s remaining amount by both the prepayment and the AP bill.
Is this expected behavior? If not, what’s the correct workflow to prepay 50%, receive and bill that portion against the prepayment, and then prepay the remaining PO balance?
