Hi Anupam,
- For REM in OPU5 scheduling parameters to be maintained for the combination of plant and planned order type PE.
- Yes, under Detailed Scheduling we need to check Scheduling and Generate capacity requirements
- To avoid performance issues during lead time scheduling you have already maintained the scheduling horizon
- With the above settings if you do lead time scheduling(2) then in CM01 you can view the capacity requirements.
