With report filters you can choose whether a report with filters will automatically render or not.
To edit report filter settings:
Note: The advantage of doing it this way is that it allows you to create a report that renders with the most common filter criteria (e.g. the My Work Due Soon report shows items assigned to the logged in user due in the next 7 days) but also allows the user to select new filter criteria (e.g. the My Work Due Soon report allows the selection of another user and new due dates).
Note: The advantage of doing it this way is the page the report is located on should launch more quickly.
