What is DE-R-001?
DE-R-001 is a fatal validation rule defined in the EN 16931 specification (DEU national rules). It validates the PaymentMeansCode element under PaymentMeans in the UBL invoice XML.
When this rule fires, the invoice is rejected by Peppol access points and never reaches the buyer.
Target path: /Invoice/cac:PaymentMeans/cbc:PaymentMeansCode
Why This Error Matters
Invoice will be rejected by German XRechnung validators. Germany has additional mandatory fields beyond EN16931 baseline, including seller contact details, complete addresses, and buyer reference (Leitweg-ID).
DE-R-001 is a hard failure — the invoice must be corrected and re-sent before it can reach the recipient.
German XRechnung portals and Peppol access points will reject invoices without payment instructions. Without an IBAN and payment method, the buyer has no way to pay, which delays payment.
