What does PEPPOL-EN16931-R010 mean?

It means the buyer party in your invoice has no cbc:EndpointID element. Peppol requires the buyer electronic address (BT-49) to route the document, and the rule is flagged fatal, so validation stops there.

Can PEPPOL-EN16931-R010 be auto-fixed?

Not fully. The correct participant ID is external business data that cannot be inferred from the invoice, so Invoice Navigator detects the error and prompts for the buyer's Peppol identifier, then inserts a correctly formed EndpointID with the right schemeID.

Which schemeID should I use for the buyer EndpointID?

Use the CEF EAS code matching the identifier type: 0088 for GLN, 0190 for Dutch OIN, 0192 for Norwegian organisation numbers, 9930 for German VAT IDs, 9944 for Dutch VAT IDs. A schemeID outside the EAS code list fails a separate code-list rule.

Can I use the buyer's email address as the electronic address?

No. BT-49 must be a registered Peppol participant identifier, not an email or postal address. An email value will pass R010 structurally but the document will not route and the Access Point will reject it.

Which ERP systems most often cause PEPPOL-EN16931-R010?

SAP, Odoo, Microsoft Dynamics 365 and Exact Online all store the buyer endpoint in customer master data rather than on the invoice. If the Peppol identifier field is blank on the customer record, every invoice to that customer fails R010.

Buyer electronic address (EndpointID) MUST be provided

This is the rejection, word for word: „[PEPPOL-EN16931-R010] PEPPOL-EN16931-R010 fires when the buyer party in your invoice has no cbc:EndpointID element. The buyer electronic address (BT-49) is what the Peppol network uses to route the document to the right receiver, so Access Points reject the invoice outright when it is absent. This is the single most common Peppol routing error, because most ERP systems store the buyer participant ID in customer master data rather than deriving it from the invoice itself.“

The Peppol Schematron rule PEPPOL-EN16931-R010 has context cac:AccountingCustomerParty/cac:Party and asserts test="cbc:EndpointID" with flag="fatal". XPath: /Invoice/cac:AccountingCustomerParty/cac:Party/cbc:EndpointID (or /CreditNote/... for credit notes). The element itself is not enough: the schemeID attribute is mandatory and must carry a code from the CEF Electronic Address Scheme (EAS) code list — for example 0088 (GLN), 0106 (Dutch KvK-linked EAS), 0190 (Dutch OIN), 0192 (Norwegian org. no.), 9930 (DE VAT), 9944 (NL VAT). A missing or non-EAS schemeID does not trigger R010 but will fail the companion code-list rule instead, so both must be correct before the invoice passes.

What to have readyBuyer Endpoint ID · Endpoint Scheme (EAS code)

What we doAdd cbc:EndpointID inside cac:AccountingCustomerParty/cac:Party and set a schemeID from the CEF EAS code list. The value must be the buyer's registered Peppol participant identifier, not a free-text address or email. Invoice Navigator flags the missing endpoint and prompts for the participant ID before applying the fix, because the correct value cannot be derived from the invoice.
