Update Material Requirements Plan

Use the Update Material Requirements Plan screen to identify the material requirements necessary to meet a company's product demand.

You can enter independent demand (demand that is not tied to a higher level assembly) for parts using the Manage Sales Orders screen in Costpoint Sales Order Entry, Manage Inventory Reservations and Manage Inventory Requests screens in Costpoint Inventory, or Manage Master Production Schedules screen in Costpoint Master Production Scheduling. Materials Requirements Planning (MRP) takes this independent demand, explodes manufacturing bills of material as necessary, and determines, part-by-part, what and when material needs to be purchased and manufactured to meet the requirements.

MRP produces the following:

  • Planned orders, which inventory planners can turn into manufacturing orders or requisitions
  • Planner action messages, which alert planners of the activities they need to perform
  • Supply-and-demand information stored in a view for generating standard and customized MRP reports
Note: During requisition generation, the preferred vendor must not be flagged as a payroll vendor, and its Approval Code must not be Not Approved or Pending. The vendor's Vendor Status for PO must not be On Hold.

Use this function to rerun MRP. Whenever there are modifications to supply or demand, you can run MRP to capture the modifications and modify the schedules. MRP is typically run during the night or on the weekend, when users are not accessing the Materials data.

You can use this screen with or without the Master Production Scheduling (MPS) module. If you implement the Master Production Schedule, you can plan and schedule end-item products through the MPS module. You can then use the forecasts, orders, and requirements from the MPS function to drive the material requirements planning process. You can decide whether to use this screen to plan MPS-planned parts, or to use only the Update Master Production Schedules screen. Select the Plan MPS Part Requirements check box in the Corporate Settings block of the Configure Materials Requirements Planning Settings screen to indicate which screen you want to use.

Note: Only one user can run this function at a time, and you cannot run it while the Update Master Production Schedules process is running.

You can run this process while other users are logged in the system performing other functions in the Materials domain, but it is best not to add or modify manufacturing bills of material while the MRP process is running.
