In order to determine the safety stock level, you must first specify the risk of a material shortage and also the desired service level.
The safety stock depends on the service level that you specified in the MRP 2  view of the material master record and on the accuracy of the forecast.  The more accurate the forecast, the smaller your safety stock can be.
You can specify a minimum safety stock. If the result of the safety stock calculation is lower than this limit, the safety stock is then automatically set to this minimum value. You enter the minimum safety stock in the material master record ( MRP 2 screen ).
