[Former Member]

Hi,

I want to know how to use USER_COMMAND in alv grid. I want when I click on any field of alv grid columns , it open different screen as a alv grid format.

Hi rakesh,

1. In alv we cannot use AT LINE Selection

2. For alv, there is a special syntax, so that when we double-click on alv,

our FORM / routine is called and there we display another alv.

3. just copy paste to get a taste of interactive alv.

4.

hi,

follow this logic:

*Perform at_user_command.

first create form at_user_command and pass this formname to the parameter I_AT_user_command of the FM Reuse_alv_grid_display.

form at_user_command using ucomm1 like sy-ucomm

selfield type slis_selfield.

use the code for capturing the code when clicked on a fieldname or line.

endform.

this should resolve the issue.
