What it means
This rule checks for cbc:MandateTypeCode within cac:PaymentMeans/cac:PaymentMandate in a UBL invoice or credit note. A mandate type code says what kind of mandate it is. EN 16931 has no business term for it. The direct debit information uses the mandate reference (BT-89), creditor identifier (BT-90) and account to be debited (BT-91).
Why it matters
EN 16931 does not use a mandate type code in its direct debit information, so this element produces a warning.
How to fix it
Delete cbc:MandateTypeCode from cac:PaymentMeans/cac:PaymentMandate. Leave any mandate reference (BT-89) in cbc:ID of the mandate. If your invoicing software adds the type code, adjust the XML export to omit it. Export again and recheck the file.
