What it means
An item attribute (BG-32) is a name (BT-160) and a value (BT-161) that describe the product. This rule checks that the attribute has no test method (cbc:TestMethod in cac:AdditionalItemProperty), text saying how the value was measured or tested, for example for a lab result. It looks at every line of the invoice or credit note.
Why it matters
EN 16931 does not use a separate test method element within an item attribute.
How to fix it
If you need to retain the test method, include it in a supporting attachment (BG-24) or write it into the item description (BT-154). Delete cbc:TestMethod from cac:AdditionalItemProperty under cac:Item on every affected invoice line or credit note line. Check the corrected file again.
