Use
If you have scrap when producing a product, the quantity to be produced has to be increased accordingly so that you receive the desired quantity. You can model scrap in the following ways:
Here you specify how much scrap is produced when manufacturing the product, independent of the manufacturing process used.
Here you specify in the production process model exactly how much scrap is produced in each processing step. You can therefore model scrap dependent on the manufacturing process used.
Scrap calculation is only relevant for products produced in-house. The System calculates the scrap automatically using the desired yield and the scrap data and increases the quantity to be produced and the component requirements. You should only use one of the above mentioned procedures for a product as otherwise too much scrap is calculated.
