We have a situation where a vendor invoice shows as closed, with no balance due, and the last settlement voucher is referencing a Prepayment Application Voucher. It was brought to my attention, because our AP department doesn't understand why it is closed and feels it should still be an open vendor invoice.


I can see that the invoice was settled/closed on the same day it was created.
This invoice was entered against a PO and this PO never had a Prepayment created for it.
Also I cannot find any other history of this settlement voucher, unlike when we normally settle prepayment application vouchers against a vendor invoice.

In those cases, the prepayment application voucher can be clearly seen as a separate line in the vendor transactions listing. See the example below. The example shown below is NOT this same vendor invoice, but a different vendor PO/Invoice series to give you an example of what our vendor transactions screen normally looks like when a prepayment application voucher is applied to a vendor invoice.

Since there were no original prepayments created against this PO, I have no idea how this vendor invoice could have ever been settled by applying a prepayment voucher.
I am able to go into Closed Transaction Editing and reverse the settlement. However, I do not know what I could be missing to figure out how this happened in the first place.
