In their proposal they argue that their implementation of multimethods for java can be translated at source level into programs. Aside from the more complex dispatching rules, theyre really as simple as that. The process of creating an agreement essentially is what triggers the program to create work orders to do a service either on a recurring basis or as a onetime job. With direct ship, multiple shipto locations, credit memos and standard invoices, you have the flexibility to create orders that fit your unique business needs. For more complex manufacturing, project manufacturing allows creating projects that group work orders that are being processed over a period of time.
