MRP Specialist is responsible to handle ordering and scheduling of dependent-demand inventories (such as raw materials, Packing Materials, paints materials and subassemblies that will be used in the production of a finished product). Base on the customer requirements, MRP Specialist should answer three questions: what is needed, how much is needed, and when is it needed. The primary inputs of MRP are a bill of materials, which tells what goes into a finished product; a master schedule, which tells how much finished product is desired and when; and an inventory-records report, which tells how much inventory is on hand or on order. This information is processed, using various computer programs to determine the net requirements for each period of the planning horizon. Outputs from the process include planned-order schedules, order releases, changes, performance-control reports, planning reports, and exception reports.
