I have a drill down ALV grid report (using oop with custom container and grid).
The problem is, when i click on back button in 100 screen, i can come back to the selection screen fine.
But when i go to the secondary screen, click back button there, i come back to basic grid fine but now when i click on back button again, it just clears the grid contents but does not come to the selection screen.
In PAI of 100 screen,
MOVE sy-ucomm TO okcode.
WHEN 'EXIT' OR
LEAVE TO SCREEN 0.
Please help and give the solution what i can do and why this is happening.
