RE: Invoice rejected
What it means
Peppol status RE in an Invoice Response means the buyer will not process the invoice any further. It is a final status.
The usual cause
The buyer rejects the invoice, not necessarily the purchase itself; the response carries a reason code, an explanation or both, and may ask for an action such as a credit note.
How to fix it
Read the reason and any action code, then send a corrected invoice, a credit note or both as requested. If you disagree with the rejection, take it up with the buyer outside Peppol.
