| # Scrap The scrap can be defined as percentage or as a fixed quantity. Scrap factor If scrap is defined as a percentage, the percentage is called the scrap factor. The scrap factor is used as follows to calculate a material's gross requirements:
    Gross requirements = (scrap factor/100% + 1) x net quantity
Scrap quantity A fixed quantity scrap can be used, for example, if a material must be cut of a reel, and a quantity is lost during cutting. The fixed quantity scrap is used as follows to calculate a material's gross requirements:
    Gross requirements = net quantity + scrap quantity
A fixed quantity scrap can be defined for a material in the BOM or for an operation. A fixed quantity scrap is mostly used for start-up effects. For example, when a machine is started, the first products must be discarded because their quality is poor. Quantity-independent materials You can use the Scrap Quantity field in the Bill of Material (tibom1110m000) details session in a special way in case of quantity-independent materials. For example, you want to include one measuring cup with a box of soap powder, regardless of the amount of washing powder (one-kilo box or two-kilo box). Create a BOM line for the quantity-independent material (in this case, the measuring cup) in the washing powder BOM. Enter the required quantity, in this case, one, in the Scrap Quantity field, and enter zero (0) in the Net Quantity field. For every amount of washing powder, one measuring cup is included. If you want to add a quantity-independent material for a specific production order, you can carry out the procedure described previously in the Estimated Materials (ticst0101m000) session for the production order.
