UBL-CR-563: An item should not state a pack quantity

What it means

The rule checks the item of every line, or credit note line, for a pack quantity (cbc:PackQuantity under cac:Item), a figure that describes how the item is packed. EN 16931 states what you bill through the quantity (BT-129) and its unit of measure (BT-130), and describes the item by its name and description. The test checks only whether the element is present, not its value.

Why it matters

The EN 16931 UBL rules advise against including cbc:PackQuantity in the item on an invoice or credit note line.

How to fix it

Remove cbc:PackQuantity from cac:Item. If the pack size matters, put it in the item name or description, for example "Box of 12". Check that the quantity and its unit of measure say exactly what you bill, for example boxes and not single items.
