What does PEPPOL-EN16931-R001 mean?

Why error PEPPOL-EN16931-R001 appears in an e-invoice and how to provide ProfileID per Peppol requirements.

PEPPOL-EN16931-R001 — Missing business process identifier

What it means

The business process identifier (ProfileID) is missing — Peppol requires it in addition to the base EN 16931 requirements. This field states which Peppol business process (e.g. billing) the invoice is processed under on the Peppol network.

How to fix it

Check that the invoice XML contains a ProfileID element with the value urn:fdc:peppol.eu:2017:poacc:billing:01:1.0 (the standard billing process). This error often shows up alongside BR-01 — both fields (CustomizationID and ProfileID) need to be provided together when the invoice is sent over the Peppol network.

Example

Wrong: the ProfileID element is missing even though CustomizationID is present. Correct: <cbc:ProfileID>urn:fdc:peppol.eu:2017:poacc:billing:01:1.0</cbc:ProfileID>.
