I need to know how to either prevent or identify potential duplicate payments for supplier invoices. I was able to find multiple threads regarding the prevention of duplicate invoice entry, and was able to find the following two that appeared to be around duplicate payment entry for each invoice:
However, neither thread really points me in the right direction as one is in regards to duplicate invoices and the other, credit notes.
What I'm trying to do is prevent a vendor from being paid multiple times for the same invoice. Would SAP standard functionality even allow this? If not, then maybe that is why I'm having trouble answering? If SAP would allow this, are there any controls that could be put in place to prevent it?
I'm in the process of writing an internal audit program for purchasing and accounts payable, and this would help tremendously as the auditor would be able to quickly check the setting and move forward.
Any help would be greatly appreciated!
