What does UBL-CR-680 mean? A UBL invoice should not include the PaymentMeans/PayerFinancialAccount

Why did my invoice fail UBL-CR-680?

The cac:PaymentMeans/cac:PayerFinancialAccount element should not be used in an EN 16931 UBL invoice. In the core model the debited (payer) account for direct debit belongs in cac:PaymentMandate/cac:PayerFinancialAccount (BT-91), not directly under PaymentMeans, so a PayerFinancialAccount under PaymentMeans is outside the core model and validators warn.

Official rule text
