Re: HOW MANY WAYS WE CAN USE CALLING A SCREEN IN MODULE POOL...?ie. call screen 9000 , dynnr = '9000'. and why we are using and where to use for 2 tabs and two subscreens"call SUBSCREEN tab1_ref1 INCLUDING sy-repid '0110'."

Hi Varun,

For every tab in the tab-strip there should be a subscreen area ie in your case it is tab1_ref1 & tab1_ref2.

Again every subscreen area should be linked with a subscreen.

    call SUBSCREEN tab1_ref1 INCLUDING sy-repid '0110'.

    call SUBSCREEN tab2_ref2 INCLUDING sy-repid '0120'.

Here 0110 & 0120 are two subscreens.

If you need further clarification you can post further.

Swaroop
