Find Modified Recurring Schedules/New Schedules

Hello Experts,

Is there any way to find out if any new report was scheduled or if any existing recurring scheduled report was modified?

For example: I need to find out if any of the existing recurring scheduled was modified or if any new recurring scheduled is created?

If I have to write a query on query builder, how would I do it on XIR 3.1 SP4

Thanks,

Izak
