User was not able to find a Shipment/Invoice to pay.
Checked all the relevant tables.
Voucher showed up in PM00400 but CTRLNUM was the same as another posted voucher.
Document does not show up in Vendor or Document Inquiry but does show up in PO Inquiry, fully posted.
I ran checklinks on payables, no relevant results.
I ran all the Payables reconcile, and it removed the voucher total from that vendor.
So still have the Shipment/Invoice but no payable. And it is still a duplicate Voucher with Recvg type.
Not sure where else to look or how to fix so I suggested a Purchase Return (Return w/Credit is the only one that works, it's a non-IV item) and then void the Credit that results from the return. Then try to re-enter the shipment/invoice.
Any ideas why this might have happened or a right way to fix it?
