Warning

CII-SR-151: Leave out the requested quantity on an invoice line

In short

Warning: worth checking.

CII-SR-151 means an invoice line carries a requested quantity (RequestedQuantity), which EN 16931 does not use. The file is still accepted; remove the element and make sure the invoiced quantity is the one you charge for.

What it means

The rule checks the delivery block of each invoice line. It must not contain a RequestedQuantity, the quantity the buyer asked for. The quantity the standard reads is the invoiced quantity (BT-129).

Why it matters

This is a warning, so the invoice goes through. The recipient only reads the invoiced quantity, so a different requested quantity is likely to be ignored. If it differs from what you charged, the extra number does nothing and can confuse a person reading the XML.

How to fix it

Turn off the ordered or requested quantity in the export of your invoicing software. Check that the invoiced quantity (BT-129) is the quantity you are charging for. The ordered quantity belongs on the order, which you can point to with the purchase order number (BT-13).
