Existing(Open) PR not Consider while MRP run in MD04

Hi team,

I am getting a issue while creating automatic PR creation by using t-code MD04.

Example:- In my material 10 qty is reoder point and current stock is 8 qty. During MRP run system is creating a PR by 2 qty. and then we have issued 2 qty from the stock. Now, again we are going to MRP run then system should be create a new PR but besides this 2 qty are adding in existing PR total qty 4 qty. But my customer need to create a new PR.

Kindly help me...
