Consumption of PIR

Greetings...

1. created PIR for SOP

2. MRP Run

3. Converted Planed order to process order

4. Goods issue to Prcoess order

5. Process order Confirmation

6. Goods Reciept

7. Goods in Stock

8. transfer Goods To another Plant under Stock Transfer Order to my another Plant.

So my Problem is PIR , is not consumed , after stock get posted .It showing new requrienment , which get consider in MRP Run.

How to avoid this , so that after GR , PIR shold get consume.

Which Strategy i should Use, right now using 10.?? What else setting i have to do for Consumption of PIR.
