Reorder point + PIR

Dear All,

Is it possible to have both reorder point and PIR to be considered together.

Case 1:

If we have Stock 200 kg

PIR 500 kg

Reorder point 100 kg

system should raise 300 kg planned order when MRP is run

Case 2:

If we have stock 50 kg

reorder point 100 kg

fixed lot size 1000 kg

system should raise 1000 kg planned order when MRP is run

Regards,

Joseph.
