I have an item with "0,00" as net value on a standard billing document.
In the sales order, item was announced with a net price different than "0".
After checking, it seems that price condition record for this item was valid at the sales order creation date but no more at the billing creation date.
Is there any chance to set up a warning or error message that appears at the billing creation time to inform that a condition record has not been found for item x or a message about a "0,00 net value item" in the document?
Thank you for your help.
