Problem with TABSTRIP?

Hi friends in have created the TABSTRIP with 3 tabs they are like TAPD, InQUIRY, SALES ORDER.

My main screen number is 100.And the screen that i have assigned for the rest three screens is 101, 102, 103.

I am confused where i have to design my 3 screens my code after creating tabstrip is like..

PROCESS BEFORE OUTPUT.

*&SPWIZARD: PBO FLOW LOGIC FOR TABSTRIP 'TAPD'

MODULE TAPD_ACTIVE_TAB_SET.

CALL SUBSCREEN TAPD_SCA.

INCLUDING G_TAPD-PROG G_TAPD-SUBSCREEN.

MODULE STATUS_0100.

*

PROCESS AFTER INPUT.

*&SPWIZARD: PAI FLOW LOGIC FOR TABSTRIP 'TAPD'

CALL SUBSCREEN TAPD_SCA.

MODULE TAPD_ACTIVE_TAB_GET.

MODULE USER_COMMAND_0100.

Please can anybody take me the correct procedure from this how to design the 101, 102, 103 screens please ..

Thks in advance.
