    SAP help says:

    The reorder point should cover the average material requirements expected during the replenishment lead time.

    The safety stock exists to cover both excess material consumption within the replenishment lead time and any additional requirements that may occur due to delivery delays. Therefore, the safety stock is included in the reorder level.


    I don't think you could change this setting (via configuration).
