Creating a Sales Order With Service Items 

You enter services in the same way as you enter a free goods item. You can also enter main or sub-items here. Using the item category group DIEN which is proposed for every service in the material master record, the system determines the item category TAX for the item. It proposes this item category for both for a main item and for a sub-item. You enter a service sub-item as a free goods item by allocating it to a higher-level item on the item overview screen. The service sub-items are also adjusted proportionally when you change the quantity in the main item. If you want to prevent this, proceed exactly as for a free goods.
