BR-DE-25-a

If the payment means is SEPA direct debit (BT-81 with code 59), group BG-19 ("DIRECT DEBIT") must be transmitted — with the data the collection rests on: mandate reference, creditor identifier and the account to be debited.

Severity: Error
Applies to: CII, UBL
Rule set: v2026-01-31

Official rule text

Wenn BT-81 "Payment means type code" einen Schlüssel für Lastschriften enthält (59), muss genau BG-19 "DIRECT DEBIT" übermittelt werden.

Why it happens

Code 59 is set because payment is collected by direct debit — but the mandate reference and creditor ID live in the accounts-receivable master data and were never mapped into the invoice format.

How to fix it

Transmit BG-19: mandate reference (BT-89, cac:PaymentMandate/cbc:ID in UBL, ram:SpecifiedTradePaymentTerms/ram:DirectDebitMandateID in CII), creditor identifier (BT-90) and the debited account (BT-91). See also BR-DE-30 and BR-DE-31, which check the last two individually.
