Official rule text
[DK-R-017] For Danish Customers it is mandatory to specify schemeID as "0184" (DK CVR-number) when PartyLegalEntity/CompanyID is used for AccountingCustomerParty
Why this error occurs
This rule only applies when another field has a certain value (for example a payment means code or an invoice type). Your file triggers the condition but does not provide the data that then becomes mandatory, or provides data that is then forbidden.
How to fix it
Either change the triggering value so the condition no longer applies, or add/remove the dependent elements as the rule text describes. Check the condition in the XPath test above to see exactly which value triggers it.
