Code 59 forbids CREDIT TRANSFER (BG-17) and PAYMENT CARD (BG-18).

Wenn BT-81 "Payment means type code" einen Schlüssel für Lastschriften enthält (59), dürfen BG-17 und BG-18 nicht übermittelt werden.

Deutsche Fassung: Amtlicher KoSIT-Text (official KoSIT assert text).

Requires: code 59 forbids CREDIT TRANSFER (BG-17) and PAYMENT CARD (BG-18).
Business terms: BG-17 BG-18 BT-81
Syntax: Binds the UBL-2.1 Invoice / CreditNote syntax and the UN/CEFACT-CII syntax
Location (UBL-2.1 path): /ubl:Invoice/cac:PaymentMeans[normalize-space(cbc:PaymentMeansCode) = '59']
Fix: Correct `/ubl:Invoice/cac:PaymentMeans[normalize-space(cbc:PaymentMeansCode) = '59']` so that code 59 forbids CREDIT TRANSFER (BG-17) and PAYMENT CARD (BG-18).
Fix (Deutsch): Korrigieren Sie `/ubl:Invoice/cac:PaymentMeans[normalize-space(cbc:PaymentMeansCode) = '59']`, sodass gilt: Wenn BT-81 "Payment means type code" einen Schlüssel für Lastschriften enthält (59), dürfen BG-17 und BG-18 nicht übermittelt werden.
Severity: fatal
Provenance source: xrechnung-ubl
Provenance assert: Wenn BT-81 "Payment means type code" einen Schlüssel für Lastschriften enthält (59), dürfen BG-17 und BG-18 nicht übermittelt werden.
