The Schedule tab is used to run the report and send a reminder with a link to the report that was run at the selected interval for the report. The email will send to the users included in the Share tab settings. If the Report Output Format is Link Reminder (dynamic), the scheduled report is simply a URL/link reminder which will run a query and display the real-time data as a result of the query. It does not save static data from the time of the execution of the scheduled report.
If the Report Output Type is not Link Reminder (dynamic), for example it is a spreadsheet or PDF format, the data is saved as static information at the time of the execution of the report. A shared user accessing the report which was saved as static data when the schedule was run will see the exact same results as the creator of the report because the report was run and saved under the settings of the report creator as static data for the other users to view. It is important to note this distinction because the receiver of the scheduled report may see data in the results which they would not otherwise have access to view.
