In the Monitor workspace, Reset can be used to rerun scheduled events and jobs with all the original schedule options and dependencies, provided the time is still within the schedule's run time window.
For example, an event ran as scheduled and failed due to feed errors, but you tried to resolve the errors and need to rerun. Or, a job ran successfully, but pulled in a wrong file and you need to rerun it with a correct file. You can Reset the scheduled event or job and it will run again as if it never ran before. The original schedule's run record and all subsequent reset records will be stored and can be viewed in the left bottom pane of the Monitor workspace.
Unlike the Submit functionality that runs events and jobs ad hoc while ignoring schedule dependencies and other scheduling options, Reset preserves all schedule options. You can reset scheduled events and jobs multiple times as long as they are within the schedule's run time window.
