Warning

CII-SR-141: Remove the unit conversion factor from the unit price after discount

In short

Warning: worth checking.

CII-SR-141 means the unit price after discount on a line has an order unit conversion factor (OrderUnitConversionFactorNumeric), which an EN 16931 invoice should not contain. Delete that element; it is only a warning, so the file is still accepted.

What it means

On each line, the unit price after discount (BT-146) sits in the NetPriceProductTradePrice block. This rule checks that the block holds no OrderUnitConversionFactorNumeric, a number for converting between the unit the item was ordered in and the unit it is priced in.

Why it matters

An EN 16931 invoice states quantity and unit price directly, so the receiving system does not apply a conversion factor and may ignore it. The file is still accepted, because this is a warning. It is worth fixing for a clean file, and worth checking if quantity and price are in different units.

How to fix it

Delete the OrderUnitConversionFactorNumeric element from NetPriceProductTradePrice in each affected line. If the item is ordered in one unit and priced in another, state the quantity and the unit price in the unit you invoice in. If your software writes the element, look for an EN 16931, XRechnung or Peppol BIS export setting.
