Instead of offering a report that displays a selection screen for the user to enter parameters, you can predefine the values in a URL. If the values entered by most users are the same, this saves unnecessary work.
http://<machine>:<port>/sap/bc/webrfc?_FUNCTION=WWW_GET_REPORT&_REPORT=RDTEST03&PARC_CARRID1=DL&PARC_CARRID2=UA
This link instructs function module WWW_GET_REPORT to execute report RDTEST03. This generates a list that displays only airline carriers with carrier ID DL or UA.
