Code controlled in the tax level table and used to determine the tax rate. The tax rate to be applied to a transaction directly depends on the nature of the transaction. Each country being ruled by its own tax rates, the tax level alone does not enable the rate to be applied to be determined. The tax can only be determined by crossing the tax rule associated with a BP and the tax level associated with a product. Thus the tax level only represents the list of the different rates applied within a same rule. In France, several tax levels can be differentiated: Standard tax, Increased, tax Reduced tax, Exemption, Super-reduced tax.
