DRP (Distribution Requirements Planning) manages the flow of materials between firms, warehouses, and distribution centers to integrate supply chain inventory information with manufacturing planning. It helps determine vehicle and warehouse capacity, loading, and dispatching to continually adjust to changes in demand. DRP is connected to both demand management in the marketplace and the MPS (Master Production Schedule) in manufacturing to provide accurate shipping information and evaluate if manufacturing priorities need adjustment. The basic DRP record tracks forecast requirements, in-transit inventory, projected available balance, and planned shipments over multiple time periods.
