Planning Material Requirements with MRP Areas

Implementation Options

This process describes how to proceed to carry out material requirements planning with MRP areas.

Prerequisites

You have converted the existing planning file entries at plant level to planning file entries at MRP area level.

You have activated MRP for MRP areas in Customizing.

You have defined the MRP areas in Customizing.

You have assigned the MRP areas to the materials in the material master.

Process Flow

You create the independent requirements of a material for an MRP area. To do this, the following options are available:

In Demand Management, you can create the Planned Independent Requirements of the materials for each MRP area. However, this is only possible if you use the make-to-stock production planning strategy.

You can create a sales order and specify a storage location. This customer requirement is assigned to an MRP area using this storage location.

You can also carry out material requirements planning for the individual MRP areas based on forecast requirements. You can carry out the material forecast for each MRP area of a material separately.

With finished products or important assemblies that are planned using planning strategies, such as the planning strategy Planning without final assembly, you enter independent requirements at plant MRP area level, as make-to-order production is planned at plant MRP area level.

You plan material requirements. During total planning with the planning unit plant, the system plans the MRP areas (if they exist) for each material one after the other and then plans the rest of the plant.

You can, however, start a total planning run specifically for one or more particular MRP areas. For this, you must maintain the scope of planning correspondingly in the IMG activity Define scope of planning for total planning in Customizing for MRP.

You evaluate the results of the planning run. In the MRP list and in the current stock/requirements list, you can specifically display and process the planning results of a material for each individual MRP area.

In the collective display of MRP lists or current stock/requirements lists, you can specifically select materials for one MRP area or for all MRP areas of a plant. However, the segregated lists are always calculated for each MRP area.

If you choose the evaluation Situation - prod.grp, you are provided with a complete overview of all MRP areas of a material. This is, however, only possible if you have defined the material as a product group.
