PEPPOL-EN16931-R101

Document reference in the wrong place (PEPPOL)

In an invoice line, a document reference may only be used to name the invoiced object (e.g. a meter number) – not for other documents.

What to do now

Tip: References to delivery notes, contracts or attachments belong in the invoice header, not in the line.

Who has to fix this?

The issuer of the invoice has to fix this. If the invoice is sent through a Peppol access point, the access point will otherwise reject it before delivery.

Where this rule comes from

This rule comes from the Peppol rule set BIS Billing 3.0, which goes beyond EN 16931. It is checked as soon as an invoice is sent as Peppol BIS Billing 3.0 through the Peppol network.
