Error codes · UBL 2.1
UBL-CR-608In your invoicing software
A UBL invoice should not include the InvoiceLine Item AdditionalItemProperty ID
This is the rejection, word for word: „[UBL-CR-608] UBL 2.1 Invoice schema does not include `cac:Item/cac:AdditionalItemProperty/cbc:ID`. This element must be removed for EN 16931 compliance.“
What to have readyNothing. The file has to be re-exported from your invoicing software; we check it again afterwards.
What we doInvoice Navigator automatically removes the disallowed `cbc:ID` element from your Invoice (UBL-CR-608).
If you enter it yourself in your invoicing software
Before
<cac:AdditionalItemProperty> <cbc:ID>value</cbc:ID> </cac:AdditionalItemProperty>
After
<cac:AdditionalItemProperty> <!-- cbc:ID removed for EN 16931 compliance --> </cac:AdditionalItemProperty>
Element order is part of the rule: if the element sits in the wrong place, the validator rejects with UBL-CR-608.
