PEPPOL-EN16931-R001

Peppol requires a business process identifier (BT-23), and it is missing.

Why it happens

The file is valid EN 16931 but was not built for the Peppol network, which additionally mandates the process identifier.

How to fix it

Set BT-23 — cbc:ProfileID in UBL — to the Peppol billing process identifier, normally urn:fdc:peppol.eu:2017:poacc:billing:01:1.0.
