Determination of Reorder Point & Safety Stock

Hi Experts,

When the MRP Type is set as "V2-Automatic Reorder Point w.ext.reqs." We have discovered whilst the forecasting is running, the system has calculated the safety stock higher than the re-order level. how could this be possible, or if the safety stock is a static figure?

I am under the impression the system will calculate both safety and re-order levels under mrp type v2, are their any other parameters we maybe missing?

Any information would be useful.

Regards,
