HI MM KS,
No. The system is considering Total Demand = 300, this is divided by 62 days (13 weeks of your factory calendar). So the daily demand is: 4.8387 CS / day. This is multiplied by your target, that is 30 days. As a result, your safety stock is 30 x 4.8387 = 145.17 CS. Then the system buy 100 CS to cover the PIR + 145.17 CS to cover the safety stock, so the PurReq is 245.17CS.
Kind Regards,
Mariano
