The difference between MRP and MPS

There are three types of MRP levels...MRP(Material requirement Planning),MPS(Master production schedule) and CBP(consumption based planning).

MPS is part of MRP

In MPS you can plan inportant assemblies seperately(critical parts and which has much influence  on the  profit a type).You can mark  the assemblies as MPS parts by assgining mrp types M0-M4 in the material master MRP1 view.

 

The main difference between both MRP and MPS is that MPS  is only good for single level BOM explosion and used for  mainly  Type A materials  which has higher  value and importance and planned carefully and greatly influence the company profits or those that  require critical  resource  whereas MRP is used for mainly type  B and C  material.

 

Mainly idea is that  master production scheduling(MPS)is a form of  MRP that  concentrates planning on the parts or products that  have great  influence  on company profits or which  the entire production process  by taking resources.These items are marked as A parts(MPS item),and are planned with  extra attention.These items are select for  a separate MPS run  that takes  place before  the MRP run.The MRP run is conducted with BOM explosion so that MRP controller  can ensure  that the master scheduling item are correctly planned before  the detail  MRP run taken place.
