Problem with gross requirement planning pir is not getting reduced

Question

Dear Gurus
I am trying to use strategy 11 for a particular finished product.(having bom and routing)
In the material master I have set mrp type pd lot size ex .strategy group 11, mixed mrp 2,item category group norm, availabilty checking group 02 .
Then I made manually pir for that material in md61 with  BSF requirement type .
Then ran the mrp for that material in md02.
Planned orders came .(In md04 screen that gross requirement line text also came as usual )Converted them to prodn order and then did the gr in mb31 with 101 mvt type. After doing the gr the pir should get reduced in md04 screen which is not happening . Where I am going wrong

Answer 1

Dear Sandip Sarkar,
                                  It usually happens run MRP and ckeck.
Strategy 11 in summary :-
1. Sales Order creation - no impact.
2. Goods Receipt - minus the quantity for the oldest planned independent in demand management.
   For e.g. if PIR is 100 and delivery 90, PIR becomes 10 (withdrawal 90).
3. Delivery - no impact as delivery is issue from sales order.
This strategy is particularly useful if you need to produce, regardless of whether you have stock or not. For instance, steel or cement producers might want to use this strategy because they cannot shut down production; a blast furnace or a cement factory must continue to produce, even if this means having to produce to stock.
You need to maintain the following master data for the finished product:
Maintain strategy group 11 on the MRP screen.
Set the Mixed MRP indicator to 2 on the MRP screen.
Maintain the item category group (for example, NORM) on the Sales Organization screen.
Maintain the Availability check field so that you perform an availability check without the replenishment lead time (checking group 02 in the standard system).
