Wrong Planned Order dates - MRP Run

Dear Experts,

Please guide to resolve the following problem:

I have uploaded the PIRs for 3 months. When I take the MRP run, the system is scheduling the planned orders for first 2 months only. For the 3rd month's PIR the planned order are created for the PIR dates only.

For example, if the PIR (for 3rd month) is maintained on 25th of the month. The planned orders for FG & SFGs are being created for 25th only. While for 2 months the Planned orders are properly scheduled.

What could be the reason for such behavior.

The planning horizon is 90 days.

Please go to customization OPU5 and select the one for the planned order, check the field 'Sched. hor.det.' if the period maintained there is too short to conver the 3rd month, no scheduling will come up, please change that longer.
