Hi,

Try this..

In the PBO if the container is not initial then call the method REFRESH_TABLE_DISPLAY

creation of the ALV Grid Control

if g_custom_container is initial.

call the method grid->set_table_for_first_display

else.

call the method grid->refresh_table_display.

endif.

Thanks,

Naren

The problem is that you can only set the fieldcat once for the SET_TABLE_FOR_FIRST_DISPLAY. If you want to modify it afterwards, I think you could use the combination of the GET_FRONTEND_FIELDCATALOG and SET_FRONTEND_FIELDCATALOG methods. So get the FC, read the specific line for the field and set the NO_OUT flag, modify the line and then pass this FC internal table to the SET_FRONTEND_FIELDCATALOG method.

Thanks Rich,

Your solution worked.



In PAI we have to use 

  call method cl_gui_cfw=>set_new_ok_code
    exporting
      new_code = 'ENTR'.

In the PBO

  if g_custom_container is initial.
    perform f_create_and_init_alv.
  else.
    perform f_rebuild_fieldcat changing gt_fieldcat.
    call method g_grid->set_frontend_fieldcatalog
       exporting
         it_fieldcatalog = gt_fieldcat[].
  call method  g_grid->refresh_table_display.
  endif.
