Retaining the selected tab in a tabbed block of selection screen

Hi,

My report has a selection screen with a tabbed block displaying 3 tabs. I want to retain the tab that was selected before executing the report and display that tab as the activetab when the user back navigates from the output list of the report to the selection screen.

I tried to store the value of 'activetab' component of the tabbed block in a global variable and assigned the global variable to the 'activetab' component. But it is not working.

Is there any other way by which we can do this?

Thanks and Regards,

Tongston
