How to apply prepayments automatically on standard invoice in oracle r12.2.13? We performed below

Hi Team,

We performed the testing for ‘Apply Prepayment automatically’ on standard invoice functionality in our test instance for both PO and Non-Po based.

Before testing we have enabled the Apply advances check box at payable options and supplier is also available for prepayment invoices.

There are 2 places where this functionality can be trigger.

1.      During Invoice validation prepayment should apply automatically on Standard invoice: Which is Not working as expected. (prepayment is not automatically applying)

2.      When the payment process is run if any prepayment is available for a supplier the payment should be stopped for the invoice: Not working as expected.
