What it means
The check searches the whole file for a unitCodeListAgencyName attribute. In UBL it can sit on the quantity of a line (BT-129) and give, in words, the name of the agency that maintains the list of unit codes behind the unit of measure (BT-130). One occurrence anywhere in the file is enough to trigger the warning.
Why it matters
EN 16931 asks you to omit unitCodeListAgencyName from UBL invoices and credit notes.
How to fix it
It is worth fixing if the same warning appears on all your invoices. Ask the supplier of your invoicing software to stop writing unitCodeListAgencyName. If you build the XML yourself, remove the attribute from every element that has it and keep unitCode. Export again and recheck the file.
