What it means
This rule checks for cbc:AccountTypeCode within cac:PaymentMeans/cac:PayeeFinancialAccount in a UBL invoice or credit note. An account type code says what kind of account it is, such as a current or savings account. EN 16931 has no business term for it. The payment account details carry the account number or IBAN (BT-84), the account name (BT-85) and the identifier of the bank (BT-86).
Why it matters
EN 16931 does not use an account type code in the payee bank account details, so this element produces a warning.
How to fix it
Remove cbc:AccountTypeCode from cac:PaymentMeans/cac:PayeeFinancialAccount. If your invoicing software adds it, adjust the XML export to omit the element rather than changing the underlying bank account details. Export again and recheck the file.
