Payment Process Request skips eligible due invoices
We are on R12.0.4 of Oracle Payables. This is a new issue for us since past May 2011. Our AP dept said that the payment process request started omitting invoices. That is, some invoices are not selected when they should have been based on their due dates. User had to pay the omitted invoices separately. User said it seems like may be all the skipped invoices are PO matched invoices.
We put the following patches in production in May 2011. Patches 9066129, 10024996, 9328048, 9624188, 9665294, 8261943, 9360490, 9719114. We don't know which patch created this issue.
What can we do to tell the system NOT TO skip eligible invoices?
