Invoice Match Option

Hi,

1. I have created the PO with invoice match option as PO

2. Payment has been made against to above PO

3. Now, i have created the Receipt against above PO

4. Again, I have created the Invoice and selected the invoice match option as RECEIPT at header level.

While match the receipt following error message getting.

APP-SQLAP-10655: You cannot match to this document...

Hence, i would like to modify the invoice match option as RECEIPT for PO(which is closed for invoice) but i am unable to modify the Invoice match option due to following note getting.

you cannot change this field unless the quantity billed ,the quantity received and the amount billed are all zero
