BADI Screen Enhancement - Adding new tab to a transaction Code

Hi Guys,

I need your help regarding my development. I have a requirement to add a new tab to transaction IW31/32/33. I have found this BADI - IWO_UI_USEFLEX & also IWO1_SCREEN_MODIFY.

I created Function Group to put my screen and called my program, screen and subscreen area in the BADI under SUBSCREENS TAB. But none of them was able to add a new tab to the said transactions.

Can anyone share some of your bright ideas. I really need your help for this one. Thanks.
