What it means
An item attribute (BG-32) is a name (BT-160) and a value (BT-161). This rule checks that the attribute has no importance code (cbc:ImportanceCode in cac:AdditionalItemProperty), a code that says how essential the attribute is for the item. It looks at every line of the invoice or credit note.
Why it matters
EN 16931 does not use a separate importance code for an item attribute.
How to fix it
Delete cbc:ImportanceCode from cac:AdditionalItemProperty under cac:Item on every affected invoice line or credit note line. Keep the attribute name and value. Check the corrected file again.
