MIRO or FB60
Duplicate payments were sent to a vendor due to the processing of an incoming invoice. One payment was made because the invoice was processed by way of a purchase order using MIRO. The other payment was made based upon an invoice that was processed through FB60 without a purhcase order. The amount, company code, vendor and reference were identical. Does SAP not review for duplicate invoices using FB60? Is Best Practice to activate G/L postings within MIRO and allow for non-po related invoices to be processed through there? What other processes exist to stop duplicate payment/invoicing within SAP?

yes, I am talking about that field
you could be right, I have never seen this working. And if you can do, you are in a better position, because in LIV there is a customizable check on double postings:
Check on double posting
Check all fields of the two invoices, at least one of them has to differ...
