What it means
The item on every invoice or credit note line should not contain a cbc:Keyword element. In UBL it holds a search word or tag that describes the item. EN 16931 has no business term for it.
Why it matters
EN 16931 does not use the separate keyword field on invoice or credit note lines.
How to fix it
Leave cbc:Keyword out of the invoice export without clearing keywords from your product records. If a keyword is important to the buyer, write it in the item name or description. If you build the XML yourself, delete every cbc:Keyword from cac:Item on each cac:InvoiceLine or cac:CreditNoteLine, then recheck the file.
