Warning

CII-SR-115: Do not put a minimum quantity on the price of a line

In short

Warning: worth checking.

CII-SR-115 means the price before discount on an invoice line states a minimum quantity, which EN 16931 does not use. Remove it from the price block; the file is still accepted.

What it means

The gross price block of an invoice line (GrossPriceProductTradePrice, inside SpecifiedLineTradeAgreement) contains a MinimumQuantity, the smallest quantity for which the price applies. The invoice standard has only the price and the invoiced quantity (BT-129).

Why it matters

Price tiers and quantity bands are not part of the invoice standard, so recipients ignore them. This is a warning and the invoice is still accepted. It is worth fixing if the buyer wants to check the price tier, because the unit price on the line must then already be the price for the quantity invoiced.

How to fix it

Remove the minimum quantity from the price of every line. Make sure the unit price on the line is the price that applies to the quantity you invoiced. If you want the buyer to see the price tier, add it to the item description or a line note.
