With this feature it is possible to set up a specific item sales tax group for a released product variant. The specific item sales tax group for a released product variant can be set up both for sales and procurement. If a specific item sales tax group is set up for a released product variant for sales, then this item sales tax group is used as default when creating a sales quotation and sales order line. Similarly for purchase order, purchase requisition, and purchase requisition, if a specific item sales tax group is set up for a released product variant for purchase, then this is used as default. If no specific item sales tax group is set up for a released product variant, then the item sales tax group setup for the product is used as default.
