Rescheduling in planning time fence

[Former Member]

Dear experts,

I have a scenario where we are implementing MRP for a trading unit. We are updating the sales forecast quantities as monthly requirements in PIR. The requirement is that the lead-time is 90 days for the materials. So even if there is shortage in the first 90 days no procurement proposals should raise. After 90 days, the procurement proposals should be generated for the requirements. We have mapped the MRP type P2 and entered the planning time fence for this requirement and that is working fine. We have put zero in the rescheduling horizon and removed the tick marks against the firmed receipts in the rescheduling horizon.

We have updated the requirements for the months of June, July, August, September, October, November & December.

In the MD04 screen, the planning time fence end is on till the end of Aug month. We have a PO on 15.08.2017 and that PO is considered for the June, July and August month requirements and is reduced. This should not happen as we have removed the rescheduling check and reschedule in should not happen. Only reschedule out should happen as standard. The reason to update the June, July & Aug. month requirements is that If there is stock then we can sell from that so it can be considered for net requirements calculation.

If i use MRP type as PD then reschedule in is not happening and reschedule out is working fine as per standard. This rescheduling check is not working if it comes within planning time fence.

Please suggest a way to avoid the reschedule in within planning time fence period.

Thanks in advance
