Alternate routings are useful for managing variations in the manufacturing process of an item. For example, a substitute machine is used while the primary machine for a process is being repaired. Like routings for regular items, alternate routings for co-products are assigned when work orders are generated. Routings are not required and are not used in MRP or for developing standard costs.

Only a base process can have alternate processes or routings. This is not true for co-products and by-products because they do not have a formula or process independent of the base process.

Define alternate routings for a base process in Alternate Routing Maintenance (14.15.1).
