My Client wants to use % based safety stock for components and i found that service level field in material master will suit the requirement. But when i add in 10% as my service level for a component and my PIR is 1000, stock=0, system created a planned order for 1000 without considering the service level and i tried other scenarios by adding stock and increasing the PIR but found no significance of service level. Is there any settings missing? iam using PD & VV types for different components. please guide me on this.
