Hi,

I think this particular case can be resolved by writing the logic for the Double click function code.

Under the function code &IC1 write the below logic

Call screen 100 ( here screen 100 is your ALV output container screen)

Try this logic.

But what you will do with the error data. you tell me that.

Don't update some error values to DB.

if you don't want error then check this sample code.

report  ztest_alv_edit.

data: it_flight type standard table of sflight.

data: it_fcat type lvc_t_fcat,
      wa_fcat type lvc_s_fcat.

data: grid type ref to cl_gui_alv_grid,
      cont type ref to cl_gui_custom_container.
class lcl_event_receiver definition deferred.

data: g_handler type ref to lcl_event_receiver.
