E-invoice rule Peppol BIS Billing 3.0

PEPPOL-EN16931-R101: Line 1: inside a line, cac:DocumentReference

Line 1: inside a line, cac:DocumentReference is only used for the invoiced object, so it needs cbc:DocumentTypeCode with the value 130.

Original wording of the rule

Element Document reference can only be used for Invoice line object

Source of the quotation: Peppol BIS Billing 3.0 (OpenPEPPOL, peppol-bis-invoice-3)

How to fix it

1. Open the XML file and find the element cac:DocumentReference/cbc:DocumentTypeCode.
2. Add or correct the element the way the wording of the rule above asks for.
3. Save the file and check it again with our checker. It runs in your browser, the file is never uploaded.

A correct UBL 2.1 snippet

<cac:DocumentReference
    xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2"
    xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">
  <cbc:DocumentTypeCode>130</cbc:DocumentTypeCode>
</cac:DocumentReference>

The snippet is only the part of the document the rule is about. Put it in the right place inside your invoice; the namespaces are written here only so that the snippet reads on its own.

Our check is not complete: we do not check the XSD schema and we do not implement every rule, and a file that passes says nothing about whether the buyer or the Peppol network will accept it. Licences for the quoted wordings are listed in our sources.
