Original rule text
[BR-DE-20] "Debited account identifier" (BT-91) soll eine korrekte IBAN enthalten, wenn in "Payment means type code" (BT-81) mit dem Code 59 SEPA als Zahlungsmittel gefordert wird.
not(normalize-space(cbc:PaymentMeansCode) = '59') or xr:checkIBAN(string(cac:PaymentMandate/cac:PayerFinancialAccount/cbc:ID))What this rule requires
The rule applies when the payment means type code (BT-81) is 59, indicating SEPA. In that case, the debited account identifier (BT-91) must be a valid IBAN. The test is satisfied if the code is not 59; if it is 59, the account identifier is checked for IBAN validity. This is a warning, so the document is not rejected, but the validator recommends a correct IBAN.
How to fix
If PaymentMeansCode / TypeCode is 59, ensure the account identifier in cac:PaymentMandate/cac:PayerFinancialAccount/cbc:ID (UBL) or ram:PayerPartyDebtorFinancialAccount/ram:IBANID (CII) is a valid IBAN. If the code is 59 and the IBAN is correct, check that it is formatted as the rule's IBAN check accepts.
