I have created an ALV Editable Report using Custom Container (Using CL_GUI_ALV_GRID), Every thing is going perfect, I have also created PF STATUS and set AT-EXIT-COMMAND for BACK, EXIT & CANCEL Button, but when I Press back button after ALV List, then it is going to another list without any list screen rather than back to selection Screen.
LEAVE TO SCREEN 0, but the problem is same.
Debug and check the value of SY-UCOMM.
LEAVE TO SCREEN 0 works well to focus on selection screen.
