Hi,
We have few materials which are planned separately at storage location level, for this MRP4 settings maintained with Sloc MRP indicator as 2, special procurement type 40 (Purchase Order-External procurement), re-order point qty and replenishment qty as shown below.

MD04 - 1512 is the stock at OSW2 storage location, there is a open PO for 1728 EA. So, we expect to create purchase req for balance qty in considering open PO to meet the reorder point.

But MRP run creating PR for 3672 EA, that means it does not take open PR's or PO's into account while generating the procurement proposals qty. The expected PR qty is = 5166-1512-1728 = 1926.

Can you help me to understand how do we fix this problem? Are they any settings i am missing at storage location level MRP?
I think we can solve this if we use MRP area concept at planning level, but we don't use MRP area at present. So, checking if we can fix this issue at storage location level planning itself since we are in ECC.
