What triggers the net requirements calculation in the Material Requirements Planning (MRP) process?

The net requirements calculation in the Material Requirements Planning (MRP) process is primarily triggered by planned and exact requirement quantities. This is because MRP aims to ensure that the organization has the right materials available when needed. The calculations assess the difference between what is needed (those plan quotas) and what is currently on hand, allowing for precise planning on what must be ordered or produced.

When a planned requirement is established, it sets the baseline for how much material is necessary for production. Exact requirements, often derived from finalized production schedules orustomer orders, refine this further, prompting the MRP system to calculate net requirements to fill the gap between on-hand inventory and required levels. This ensures optimal inventory management and helps avoid excess stock or shortages, which can disrupt production processes.

The other potential triggers for the MRP process, such as stock number audits, forecast consumption updates, or material reservation requests, play roles in inventory management and planning but do not directly initiate the calculation of net requirements. These processes provide valuable data that can influence planning but are secondary to the initiation triggered by planned and exact requirements.
