Warning

UBL-CR-579: The seller's item number should not carry dimensions

In short

Warning: worth checking.

UBL-CR-579 means the seller's item identification on an invoice or credit note line has a measurement dimension (cac:MeasurementDimension) attached, which EN 16931 does not use. It is only a warning. Remove it, and give the size in the item description or as an item attribute.

On this page

What it means

On every invoice or credit note line, the cac:SellersItemIdentification block for the seller's item number (BT-155) should not contain a cac:MeasurementDimension block. In UBL it holds a measurement such as length, width, height or weight.

Why it matters

EN 16931 does not use measurement dimensions inside the seller's item identification.

How to fix it

Omit cac:MeasurementDimension from cac:SellersItemIdentification in the invoice export. Write any measurement you need to retain in the item description, or list it as an item attribute (BG-32). If you build the XML yourself, delete cac:MeasurementDimension from cac:SellersItemIdentification.
