Sales Order Stock is special stock (E) to specific customer demand .You do not need to create a separate Safety Stock because your fixed demand comes from Sales Order it self and requirement pass into planning through requirement type & class to production from sales .
Now safety stock does not depend on the source of demand ( Sales Order etc ) .Its totally based on the service level percentage over the period and your consumption pattern ( let say 18 months sales consumption ) .
Basically , you need the safety stock when you have any un-expected demand and you wanted to meet certain percentage of the demand using safety stock supply to customer .
In this context , even you keep the manual safety stock in MRP2 view for certain customer material and you may be able achieve some percentage of service level till you complete the total demand .But risk will be , the same stock can be of excess without any usage if the production is customer (MTO) depending on your actual business process.
