We have recently had several cases where credit notes (CNs) were not deducted from outstanding invoices during payment runs, which results in double or excess payments.

This is usually because a CN often has a later date than the original invoice, on which the payment term is then applied.

It happens that the invoice is due (because eg longtime blocked/not approved) and the CN not yet.

In the context of the IFS implementation, we had checked to look into setting CNs as immediately due, so that when approved, the CN would be immediately deducted from the invoices in the payment run.

At that time, this seemed not to be possible. Given the recent cases, we was wondering if it would be possible if we had a separate numbering sequence and, for example, a separate voucher type for CNs, to make sure that credit notes become immediately due.

Other suggestions are also welcome!

Thanks!
