CII-SR-157: Leave out the net weight on an invoice line

What it means

The rule checks the delivery block of each invoice line. It must not contain a NetWeightMeasure, the weight of the goods without packaging. EN 16931 has no weight field.

Why it matters

This is a warning, so the invoice goes through. The recipient's software has no field for weight on a line and is likely to ignore it. Anyone who needs the weight, for freight or customs, will not find it in the structured data.

How to fix it

Turn off weight fields in the e-invoice export of your invoicing software. If the buyer needs the weight, add it as an item attribute (BG-32), with a name such as Net weight and a value such as 2 kg. A short mention in the item description (BT-154) works too.
