I issued IN1234 for R3000 to a supplier with the correct ref and PO number - CORRECT!
I issued IN1235 for R400 to a supplier with the correct ref and PO number - CORRECT!
But then I incorrectly duplicated IN1234 including IN1235 information (this was a case of sending the invoice out by accident)
The supplier has paid R400 against the incorrectly issued IN1234
How should I rectify this?
Our system only has IN1234 and IN1235 on it and they are correct but our supplier is sitting with 2 x invoices with IN1234. They won't just disgard invoices that have been issued. Please help!
