If the component scrap is only relevant to the individual BOM, then it can be maintained in the BOM Item detail screen Component Scrap - MRP4 View If the same component scrap applies to a material in a number of BOMs, then it can be maintained in the material master record.
For example, the "efficiency" of an air conditioner is often taken to mean the ratio of the energy it pumps out of a room to the energy it draws from the electrical outlet. A good result for that might be, for example "4.3" That would mean that paying for 1 Joule of electrical energy is enough to pump 4.3 Joules of heat out of your house.
