Warning

UBL-CR-616: Item attributes should not have a property group

In short

Warning: worth checking.

UBL-CR-616 means an item attribute on a line contains cac:ItemPropertyGroup, which EN 16931 does not use. Remove this child group, keeping the attribute itself and its name and value.

On this page

What it means

An item attribute (BG-32) has a name (BT-160) and a value (BT-161). This rule checks that cac:AdditionalItemProperty does not contain cac:ItemPropertyGroup. It looks at every line of the invoice or credit note.

Why it matters

EN 16931 does not use the cac:ItemPropertyGroup element within an item attribute.

How to fix it

If the group name helps the buyer, put it at the start of the attribute name, for example "Dimensions: width". Delete cac:ItemPropertyGroup from cac:AdditionalItemProperty under cac:Item on every affected invoice line or credit note line. Keep cac:AdditionalItemProperty and its name and value, then check the corrected file again.
