What it means
An item attribute (BG-32) is described by a name (BT-160) and a value (BT-161), both in plain text. This rule checks that the attribute has no name code (cbc:NameCode in cac:AdditionalItemProperty). It looks at every line of the invoice or credit note.
Why it matters
EN 16931 uses the text attribute name (BT-160), not the separate cbc:NameCode element.
How to fix it
Check that each attribute has a readable text name in cbc:Name. Delete cbc:NameCode from cac:AdditionalItemProperty under cac:Item on every affected invoice line or credit note line, keeping cbc:Name. Check the corrected file again.
