Routing is the part of a product structure listing the operations involved in manufacturing a product. Information regarding each operation in routing includes the work center performing the operation, setup and run times, tools required, etc.
Operations contained in routing are used for different calculations, of which the two most common are:
Load for planned orders in capacity requirements calculations and manufacturing orders in production activity control.
Product costing, including direct labor, subcontract costs, fixed and variable machine costs. These are based on setup and run times only, or on setup and run times plus number of persons or machines.
