Warning

UBL-CR-615: Item attributes should not have a usability period

In short

Warning: worth checking.

UBL-CR-615 means an item attribute on a line contains cac:UsabilityPeriod, which EN 16931 does not use. Remove this group and put any dates you need to retain in the item description, or use the invoice line period if the dates describe the period the line covers.

On this page

What it means

An item attribute (BG-32) is a name (BT-160) and a value (BT-161). This rule checks that the attribute has no usability period (cac:UsabilityPeriod in cac:AdditionalItemProperty), a period during which the attribute is valid. It looks at every line of the invoice or credit note.

Why it matters

EN 16931 does not use a usability period inside an item attribute. The invoice line period (BG-26) is a separate field with a different purpose.

How to fix it

If the dates describe the period the line covers, use the invoice line period (BG-26). Otherwise write any dates you need to retain into the item description (BT-154). Delete cac:UsabilityPeriod from cac:AdditionalItemProperty under cac:Item on every affected invoice line or credit note line. Check the corrected file again.
