Depending on the customizing of the calculation procedure the information on the tax categories for the customer is automatically processed. The tax category information on the company code must be taken into account in the way that taxes for which the company code is not an agent at all must not occur in the calculation procedure. For further information please refer to the standard SD documentation about pricing. It is possible to set up the calculation procedure in a way that the whole tax determination is done automatically by taking into account the information about the tax categories from the customer master data.
