AP payment voucher match posts credit discount value to AP instead of credit amount

Hi

I am using JDE Oracle E1 9.2 and have come across an issue.

In manual payment with voucher match, the issue I am experiencing is related to matching a credit in the payment transaction. The payment terms include a discount but if the payment is made without taking the discount, then the 'discount' value is credited to AP and the difference between what should have credited to AP and what was actually credited, created an exchange 'PG' value.

So:

Invoice €5,000 exchange rate .85 = £4,250

Credit -€100 exchange rate .9 = £85

Discount terms of 10% but none taken.

Payment entered for €4,900/£4,165

The CA ledger posts:

Dr AP €5,000
