I am facing the following issue. For an Italian Intrastat specific regulation it is required to split some additional costs entered in the customer invoices (e.g. packaging costs) in the other billing items contained in the same invoices instead considering them services to be listed in a separated Section of the Italian Intrastat reports.
At the moment I need to manage the packaging cost with a specific material code in the billing document but I do not want to associate to the packaging item a commodity code cause its value need to be splitted, only for an Intrastat rule reason, into the other material commodity codes of the same invoice according to the quantity of the other items sold.
Could you please help me in finding a solution?
Thanks in advance
