The SAP System allows you to post receipts of planned by-products and unplanned by-products directly from an order or a network.

A by-product is a product that is created automatically during the production process of another item, the main product. For example, coke and tar are obtained as by-products in the production of gas.

If the by-product has not been planned in the order, you must enter the goods receipt manually.

A by-product can be planned in the order as a component with negative quantity. For this component, a reservation item is created automatically with movement type 531 (receipt of by-product). You can enter the goods receipt as follows:

• automatically during order completion confirmation
• manually with reference to the order or reservation
