BR-25 — Missing item name
What it means
Each invoice line must state an item name. Without a name, the buyer can't tell what exactly the payment is being requested for.
How to fix it
Check that the Item section of each line has a Name element filled in
with a clear description of the good or service.
Example
Wrong: the Item section has no Name element.
Correct: <cac:Item><cbc:Name>Konsultācijas pakalpojums</cbc:Name></cac:Item>.
