Can we restrict an invoice to check for the prepayment existence and if prepayments exist, should no

Hi folks...

In Oracle EBS R12 (12.2.6 OR 12.2.5 version) can we restrict an invoice to check if PO matched prepayment exists and if a prepayments exist, should not allow user to process payments?

As an internal control requirement, my client need to build a system enabled control that check if any PO matched prepayments exist while processing an invoice and should not allow user to process payment is condition is positive.

Please advice.

Thanks and regards
