Read column in 'REUSE_ALV_GRID_DISPLAY'

Hi Experts,

I created a double click event using 'i_callback_user_command' in 'REUSE_ALV_GRID_DISPLAY'.

I can obtain the row-ID by (ls_selfield TYPE slis_selfield) and (ls_selfield-tabindex).

However, may I ask is it possible to read the column-ID in 'REUSE_ALV_GRID_DISPLAY'.

BR,

King
