Trouble with enabling Standard toolbar buttons on output screen.

Hi All,

I had created a new GUI STATUS name 'STANDARD' in my report program.

SET PF-STATUS 'STANDARD'.

Now within i had activated BACK, EXIT, CANCEL, PRINT, SEARCH commands on STANDARD TOOLBAR. Inspite of which these buttons are disabled in the output screen. I had even deleted these entries and reentered again in SE41 (Menu Painter), but they are still disabled. Can anyone of you suggest me How can i enable them? Thanks !
