Hi Prakhar Chandel,
Suppose you have tab1(9001),tab2(9002) and tab3(9003) in the tabstrip and each one have its own subarea and the main screen is 9000 which contains the tabstrip.Let name of the subscreen be subscr.
PBO (of 9000)
CALL SUBCREEN subscr INCLUDING sy-repid v_dynnr.
(Now in the PAI of the screen 9000 in user_command module write the below code)
PAI (of 9000)
CALL SUBSCREEN sbuscr.
Module user_command.
( in this )
Case.
When 'tab3'.
v_dynnr = 9003.
tab-activetab = 'Tab3'.
Endcase.
or you can use leave screen to 9003 or call screen 9003.
This will take to you to the third tab. Hope this helps you.
With Regards
