Please explain what you understand about MRP profile, MRP group, MRP controller and MRP type.

MRP Profile : All the MRP 1,2,3,4 views in the material master data are entered in this profile and create MRP profile.

When you are creating Material Master in MM01 while entering the plant and storage location enter your MRP profile so that you do not need to enter the MRP data again

MRP Group: It is a planning strategy for carrying out the MRP.

In this group there are two types from procurement side

1) MADE TO ORDER In this once sales order is booked, MRP will run and the P.R will be converted to P.O.

2) MADE TO STOCK: Depends on the forecast model they will plan material and keep the finished product in STOCK You can create the MRP Group so that material can be tracked.

MRP groups are used when the plant division for planning is not enough for the division of the different materials MRP requirements. You assign different groups according to the requirements to run MRP (different Settings). These settings will be taken in account when you run MRP for single item or total planning. 

Setting --> SPRO --> MM --> Consumption based planning --> Define MRP group.

MRP controllers : It is like a production controller in an industry. He will plan all the required material for the daily plan.

It will be classified according to the materials & Buyer like 

Casting - one MRP controller

Forging - One MRP controller

All Bought Ourt - One MRP controller

Sheet Metal - One MRP controller

MRP controller is the person in charge of the MRP run for the materials. It is still a further division on your MRP. This is work load related. You can have one MRP controller for materials with different MRP groups. 

Setting --> SPRO --> MM --> Consumption based planning --> Master data --> Define MRP group.

MRP types : In the MRP types different categories are there 1) Produce to Demand

2) Consumption based planning

3) Forecast based planning

It is procedure that you set in the system on how the Material is planned

- Reorder Point

- Seasonal requirement

- Replenishment

- Vendor Managed

- Forecast Based

- Master production Scheduling

Setting --> SPRO --> MM --> Consumption based planning --> Master data --> Define MRP types

In Master production scheduling, finished products and important assemblies, socalled master schedule items, are planned separately and with extra attention. Only the master schedule items are planned in this planning run. The system creates dependent requirements for the BOM level directly below the planning level. It does not, however, plan levels below this.

Planning Time FenceYou can protect the master plan from any automatic changes to master schedule items in thenear future by using a planning time fence. Within the planning time fence, the system does notautomatically schedule or change the procurement proposals. Therefore, the MRP controller hastime to plan the master schedule items manually. However, to support the MRP controller, thesystem can create necessary procurement proposals and schedule them for the end of theplanning time fence. You can then schedule these procurement proposals manually as you wish.
