The MRP group is known as an organizational object that can be used to allocate special control parameters for planning to a group of materials. You can maintain MRP groups if planning control per plant is not precise enough for your requirements and you want to allocate certain material groups different control parameters from the plant parameters.

Objective

To define MRP Groups for the assignment of materials.

Where to used

MRP groups are defined with these specific control parameters and are assigned to the material in the material master record (MRP 1 screen).

Example

The following control parameters can be set for the total planning run:

• the creation indicator for the  planning run (creation of purchase requisitions, MRP lists, and so on)
• the planning horizon
• the  consumption mode

• for all materials without an MRP group, the system uses the plant parameters, or the entries in the initial screen of the planning run
• for all materials with an MRP group, the system uses the parameters recorded in the MRP group
