What does DK-R-006 mean? For Danish suppliers bank account and registration account is mandatory if payment means is 31 or 42

Why did my invoice fail DK-R-006?

For Danish suppliers using payment means code 31 or 42 (domestic bank transfer), both the bank account number and the bank registration number are mandatory. Danish domestic transfers are addressed by a registration number (branch) plus account number, so both are needed for the payment to be executable. In UBL these are cac:PayeeFinancialAccount/cbc:ID (account) and cac:PayeeFinancialAccount/cac:FinancialInstitutionBranch/cbc:ID (registration number).

Official rule text

For Danish suppliers bank account and registration account is mandatory if payment means is 31 or 42

Common causes

Only the account number given, without the 4-digit registration number
IBAN supplied where the Danish registration+account pair is expected for codes 31/42
Registration number concatenated into the account ID instead of the branch element

How do I fix it?
