What is BR-DE-25-a?
BR-DE-25-a is a fatal validation rule defined in the XRechnung (Germany) specification (DEU national rules). It checks whether when payment is by direct debit (sepa), the mandate reference identifier is....
When this rule fires, the invoice is non-compliant and will be rejected by Peppol access points and national validation services. The sending system receives a rejection response and the invoice does not reach the buyer.
Why This Error Matters
Invoice will be rejected by XRechnung validation. German public sector recipients require complete SEPA direct debit information for automated payment processing.
BR-DE-25-a is a hard failure. Invoices that trigger this rule are rejected at the access point and never reach the recipient. In Peppol networks, this means your sending system receives an MLR (Message Level Response) with a rejection status. The invoice must be corrected and re-sent, adding delay to your payment cycle.
