PIR's getting reduced from next months qty in strategy 11

Hi All,

I am into Process industries and my planning strategy is 11. We do planning in months and enter quantities for a whole year. For example:

Jan Feb Mar April May

52500 To 50250 To 52500 To 51750 To 52500 To ........

Every month MRP is executed for a single month PIR quantity where in we have fixied planning horizon as 28 days and we select Processing Key as NETPL. But we produce more that what we planned. Take example as, for Jan month planned qty is 52500, we may produce 54260 or more. But when i start planning for next month, my PIR qty from Feb is reduced say, 49680 To. I want to know how to arrest this reduced qty (Withdrawal qty) in PIR. I don't want system to reduce this PIR qty.

Can you tell me what Consumption mode i need to select and how many days i need to maintain in Backward/Forward Consumption?

Please help me.....

Best Regards,
