Maintenance Plan Scheduling - IP30
I am new to SAP PM and would like to get clarified about a few points in connection to preventive maintenance planning.
What is the significance of the 'Interval for Call Objects' field in IP30 layout vis-a-vis the scheduling period maintained in the maintenance plan? If we are running a batch job for scheduling by creating variant, we do mention the start date, time for the batch job. Does this job continue for an indefinite time, regardless of what scheduling period is maintained in maint. plan (if not manually terminated using SM37)?
In what scenarios should we use Scheduling Indicator as 'Time' and as 'Time - Key Date'?
Thanks in advance.
