A Run Control ID must be created to run many reports in PeopleSoft. If a run control is created that is unique to a specific report, it can be used to run future reports. The advantage to this method is that all parameters are saved with the run control. When running future reports you would only have to change a few parameters (e.g. Start Date, End Date, etc.) instead of entering all report parameters. If you create one run control to use for all reports, then you will need to change all the report parameters each time.
