Releasing hold on invoice after partial receipt

Hi

We have the below requirement..

PO is released for 100 Qty. Invoice match option is PO.

First we received an invoice for 25 pcs and invoice got created in system and it automatically went on hold for no receipts were found.

Now the receipt is made in the system for 25 pcs. Invoice is still on hold. Scheduled Invoice hold release program does not release the hold on this invoice even after receipt is made.

After few weeks, 2nd invoice comes for 75pcs and again this goes on hold as there is no receipt.

Next day receipt is made in system for 75 pcs. Scheduled invoice hold release program now releases both invoices.
