BR-DE-1Eine Rechnung (INVOICE) muss Angaben zu "PAYMENT INSTRUCTIONS" (BG-16) enthalten.

Why does BR-DE-1 happen?

Many systems print bank details only in the footer of the PDF. They are visible to a human but entirely absent from the structured data. The expression only checks that the group is there at all: an empty cac:PaymentMeans already satisfies BR-DE-1. What has to be inside it comes from other rules — the payment means code BT-81 is required by BR-49, not by BR-DE-1.

What the validator checks

The expression the official KoSIT rule set evaluates — not paraphrased, but read from the Schematron file it ships. UBL and CII address different document trees, so the same rule reads differently in each.

How do you fix BR-DE-1?

Populate BG-16 as structured data: payment means code (BT-81) and, depending on the method, the account details such as IBAN in BT-84. Free text in the footer does not count. Which account group belongs there is decided by the code in BT-81: for a credit transfer (30, 58) BR-DE-23-a requires group BG-17, for a card payment (48, 54, 55) BR-DE-24-a requires BG-18, and for a direct debit (59) BR-DE-25-a requires BG-19 — and in each case only that one.
