The Concept Of MRP in SAP

MRP in brief :

MRP is the planning tool in SAP which will look at all aspects of a material and is highly based upon the master data of the material. MRP looks at current inventory, current requirements, open purchase req/orders and so on. So if a material is required to satisfy a sales order and there is no inventory, MRP will create a planned order if the item is to be produced in house. This planned order can then be converted to a production order by the master scheduler. If the item is to be procured, then MRP will create a purchase req which the Buyer will convert to a purchase order. This is just one scenario, the system is highly configurable and will do pretty much whatever you tell based on config and master data.

- Reorder planning 
- Forecast based planning 
- Time phased planning

Details of re-order planning 
Our motive is to maintain optimum stock level of all the material included in the resource planning. so in this user or system sets a particular quantity of stock as reorder point . Whenever stock quantity fall below this point(reorder point) mrp comes into action and generates procurement proposals according to the settings done in implementation guide
