Material Requirements Planning

This process enables your material requirements planning (MRP) department to automate the procurement planning. The main function of material requirements planning is to guarantee material availability and to avoid delays in order fulfillment. The planning run checks availability of each material and, in case of shortages, creates purchase requisitions or delivery schedules if a scheduling agreement exists. Remaining shortages are displayed in the MRP app where the material planner can analyze the situation.

Procurement lead time can be longer than the time available to fulfill a demand. For this reason, you must procure the material in advance and cover your demand from stock. This process starts by creating forecast demands that are interpreted as expected customer demand. The MRP schedule runs. The system creates purchase requisitions or scheduling lines that trigger external procurement.

Optionally, purchase requisition hand over and MRP material exceptions can be handled.
