When running Material Requirements Planning (MRP), which documents are created?

When running Material Requirements Planning (MRP) in SAP, the primary documents created are planned orders and purchase requisitions.

Planned orders are internal documents that indicate when materials need to be procured or produced, based on the demand forecasts or actual demand from sales orders. These planned orders can eventually be converted into production orders or firm planned orders for manufacturing.

Purchase requisitions, on the other hand, signal the need to procure materials externally. They are requests to the purchasing department to obtain the necessary materials or components required to meet production needs. This occurs when there are insufficient current stock levels to fulfill production orders or demand.

Together, these documents play a critical role in the MRP process by ensuring that the organization has the necessary materials at the right time to meet its production schedules and customer needs. This is central to effective inventory management and production planning within an enterprise resource planning (ERP) system like SAP S/4HANA.
