Hi
i did some modification in the ALV program before . like changing field catalog etc... but i have never write a whole program in ALV and would like to try one by myself .
could you please in just 2 3 words write the step, and is there a sample program where all that apply to ALV is coded like hotspot , drill down, color, check box etc...

Hi,
go through this code.
Complete code for the ALV grid example
This example shows and ALV grid with flights. After selecting a line a change button can be pushed to display a change screen. After the changes have been saved, the ALV grid screen is displayed again, and the grid is updated with the changes.
The example shows:
How to setup the ALV grid
How to ste focus to the grid
How to set the title of the grid
How to allow a user to save and reuse a grid layout (Variant)
How to customize the ALV grid toolbar
Refresh the grid
Set and get row selection and read line contents
Make and exception field (Traffic light)
Coloring a line
Steps:
Create screen 100 with the ALV grid. Remember to include an exit button
Add a change button to the ALV grid toolbar
Create screen 200 the Change screen
