BR-DE-23-b

If the payment means is a credit transfer (BT-81 with code 30 or 58), no card data (BG-18) and no direct-debit data (BG-19) may be transmitted — the counterpart of BR-DE-23-a: a payment method carries exactly its own data.

Official rule text

Wenn BT-81 "Payment means type code" einen Schlüssel für Überweisungen enthält (30, 58), dürfen BG-18 und BG-19 nicht übermittelt werden.

Why it happens

The system always writes every payment detail it has — say, the customer's stored direct-debit mandate, although this particular invoice is to be paid by transfer.

How to fix it

Per invoice, transmit only the group matching the payment means code: with 30/58, BG-17 alone. Drop card and mandate data — or fix the code if the invoice is in fact collected by direct debit.
