PEPPOL-EN16931-R020 Seller electronic address must be provided for Peppol identification

Under Peppol rule PEPPOL-EN16931-R020, every invoice in Peppol BIS Billing 3.0 must contain the seller electronic address in BT-34 (cbc:EndpointID). R020 checks only that this address is present; the schemeID attribute (BT-34-1) is checked by BR-62, and its value must come from the EAS code list (BR-CL-25), for example "0088" for a GLN, "0192" for a Norwegian organisation number, "9944" for a Dutch VAT number, "0208" for a Belgian enterprise number or "0009" for a French SIRET. The seller EndpointID identifies the seller in the Peppol network and is the address to which invoice responses and message level responses (MLR) are sent.

Problem Description

ERROR

Peppol BIS Billing 3.0 rule (OpenPeppol)

Context and Significance

Without BT-34 the Peppol validation fails before transmission, and responses to the invoice would have no Peppol address. A missing schemeID on an existing EndpointID is reported separately by BR-62. The error usually appears when the company’s own Peppol identifier is not set in the e-invoicing settings.

Solution

In your company master data and e-invoicing settings, maintain your registered Peppol participant identifier and EAS scheme, for example 0088 for a GLN or 0106 for a Dutch KvK number. In UBL 2.1, add <cbc:EndpointID schemeID="0088">4012345000018</cbc:EndpointID> under <cac:AccountingSupplierParty><cac:Party>. Peppol BIS Billing 3.0 is exchanged as UBL 2.1.

Valid Examples

  • Seller electronic address with BT-34 = "4012345000018" and schemeID = "0088" (GS1 Global Location Number)
  • Seller electronic address with BT-34 = "987654321" and schemeID = "0192" (Norwegian Organization Number)

Invalid Examples

  • cac:AccountingSupplierParty/cac:Party contains party name and address but completely omits cbc:EndpointID
  • The company Peppol identifier is not set, so no seller cbc:EndpointID is exported (an EndpointID without schemeID, such as <cbc:EndpointID>4012345000018</cbc:EndpointID>, is reported by BR-62 instead)
