If you offer a report where the user can select any number of checkboxes to get further information, you can predefine which checkboxes are selected by specifying them in a URL. This makes sense if the checkboxes selected by most users are the same. It also dispenses with the need to display a selection screen.

This link instructs function module WWW_GET_REPORT to execute report RDTEST06. This generates a list that displays flight information only for those airline carriers with a carrier ID corresponding to checkboxes that would normally be selected on the selection screen (in this example, AA and LH).
