Which requirement must be met for carrying out MRP in a plant?

The requirement that must be met for carrying out Material Requirements Planning (MRP) in a plant is that the procurement type must be defined. This procurement type determines how products or components are acquired, whether through internal production, external purchasing, or other methods. Without a procurement type established, MRP cannot effectively calculate the requirements for materials or set the planning parameters, which are essential for ensuring that the right materials are available at the right time.

While assigning an MRP area to each storage location within a plant (the choice highlighted) plays a role in MRP configuration, it is not a prerequisite for conducting MRP itself. MRP can typically be executed at the plant level without the necessity of defining MRP areas for every storage location. Similarly, defining the MRP type in the product master and assigning MRP areas to existing purchase orders can be important for specific planning scenarios and processes, but they do not serve as foundational requirements for running MRP.

Thus, the correct understanding is that defining the procurement type is crucial for enabling MRP functionality, ensuring that planning can be conducted based on the established methods of material acquisition.
