The tax codes (VAT, additional taxes, special taxes and/or provincial taxes) can be modified on the order line if the transaction authorizes it.
They are initialized by crossing the supplier tax rule and the tax levels of the selected product.
During the transformation of an order line into a receipt line or invoice line, the tax codes entered on the order line are transferred to these documents.
The right click is used to select a tax code for each tax level. The rule set up in the tax code must be identical to the one specified in this screen. A same tax code can combine several dimension type codes "Rule +Tax level".
