The heart of a PPS system is the MRP "Material Requirements Planning"(MRP). The MRP planning run determines the exact quantities for order and production proposals on the basis of warehouse stocks, minimum stocks, replenishment times, current purchase orders, production orders and requirements. In the process, bills of material are exploded to any depth and even postponements of purchase orders and production orders are determined to the day.
Generate order proposals and manufacturing proposals based on MRP results.
