BR-23 — Missing unit of measure

What it means

The quantity must state a unit of measure (e.g. piece, hour). Without a unit, it's unclear what the number means — 10 pieces, 10 hours, or 10 kilograms.

How to fix it

Check that the InvoicedQuantity element has a unitCode attribute with a valid UN/ECE Rec 20 code (e.g. C62 — piece, HUR — hour, KGM — kilogram).

Example

Wrong: InvoicedQuantity without a unitCode attribute. Correct: <cbc:InvoicedQuantity unitCode="C62">5</cbc:InvoicedQuantity>.
