->[!IMPORTANT]
-> Make sure to have atleast 40 minutes before the scheduled maintenance run time (3:00 PM in above example) otherwise it might lead to auto-cancellation of that particular scheduled run.
+Make sure to keep these pointers in mind when using this feature
++ If you're creating a new schedule or editing an existing schedule with a pre event, you need at least 40 minutes prior to the start of maintenance window (3PM in the above example) for the pre event to run otherwise it will lead to auto-cancellation of the current scheduled run.
++ Pre event is triggered 30 minutes before the scheduled patch run giving pre event atleast 20 minutes to complete.
++ Post event runs immediately after the patch installation completes.
++ To cancel the current patch run, use the cancellation API atleast 10 minutes before the schedule maintenance time.
