What it means
This rule checks that cac:PaymentMeans/cac:PaymentMandate/cac:PayerFinancialAccount contains no cbc:CurrencyCode element. It does not check cbc:DocumentCurrencyCode, which holds the invoice currency (BT-5).
Why it matters
EN 16931 does not use a currency code for the account to be debited at this location in the UBL payment details.
How to fix it
Remove cbc:CurrencyCode only from cac:PaymentMeans/cac:PaymentMandate/cac:PayerFinancialAccount in the XML. Keep the account identifier (BT-91) and leave cbc:DocumentCurrencyCode unchanged. You do not need to change the bank account's currency in your records to clear this warning. Recheck the file.
