Class CL_SALV_FUNCTIONS, method ENABLE_FUNCTION not supported

Former Member — Mon, 28 Jan 2019 14:03:02 GMT

Hi all

I am trying to add function to the CL_SALV_TABLE as following:

START-OF-SELECTION.
  TRY.
      PERFORM query.
      IF gt_kep_alv[] IS INITIAL.
        WRITE:/ text-002.
        EXIT.
      ENDIF.
      cl_salv_table=>factory(
        IMPORTING
          r_salv_table = DATA(lo_alv)
        CHANGING
          t_table      = gt_kep_alv[] ).
      DATA(lo_func) = lo_alv->get_functions( ).
      lo_func->set_all( abap_true ).
      lo_func->add_function( name = CONV salv_de_function( 'REFRESH' )
                             icon = '@42@'
                             text = CONV string( text-005 )
                             tooltip = CONV string( text-005 )
                             position = if_salv_c_function_position=>right_of_salv_functions
                            ).
      DATA(lo_layout) = lo_alv->get_layout( ).
      DATA(ls_key) = VALUE salv_s_layout_key( report = sy-repid ).
      lo_layout->set_key( ls_key ).
      lo_layout->set_save_restriction( if_salv_c_layout=>restrict_none ).
      DATA(lo_column_gleis) = lo_alv->get_columns( )->get_column( columnname = 'GLEIS' ).
      lo_column_gleis->set_short_text( value = text-003 ).
      lo_column_gleis->set_medium_text( value = text-003 ).
      lo_column_gleis->set_long_text( value = text-003 ).
      DATA(lo_column_status) = lo_alv->get_columns( )->get_column( columnname = 'STATUS' ).
      lo_column_status->set_short_text( value = text-004 ).
      lo_column_status->set_medium_text( value = text-004 ).
      lo_column_status->set_long_text( value = text-004 ).
      DATA(lo_events) = lo_alv->get_event( ).
      DATA(lo_event) = NEW gcl_event_handler( ).
      SET HANDLER lo_event->handle_toolbar_click FOR lo_events.
      lo_alv->display( ).
    CATCH cx_salv_msg INTO DATA(lo_msg).
      WRITE:/ lo_msg->get_text( ).
    CATCH cx_salv_method_not_supported INTO DATA(lo_salv).
      WRITE:/ lo_salv->get_text( ).
  ENDTRY.
FORM query.
......
......
......
ENDFORM.

When I carry out the application, I've got:

Class CL_SALV_FUNCTIONS, method ENABLE_FUNCTION not supported for REFRESH Only Possible in Grid View

What am I doing wrong?

Thanks

This has been discussed quite a few times. I believe Paul Hardy has a blog on it. Essentially, you can't do it that way, but there are workarounds.

Personally I just use CL_GUI_ALV_GRID instead if I need user defined functions.

By the way - FORM and PERFORM are obsolete... try using classes and methods.

zero_coder In fact, it doesn't mean that you can't use ADD_FUNCTION with SALV for adding a button to the toolbar, but that this method works only with the SALV grid view mode (inside a GUI container).

In your case, your FACTORY call indicates that you are using the "full screen" mode.

ADD_FUNCTION works only if you define a custom screen with a "custom" container (would work for any other kind of container too) and you instantiate like that:

      CALL METHOD cl_salv_table=>factory
        EXPORTING
          r_container  = go_container " <== type ref to cl_gui_container
        IMPORTING
          r_salv_table = DATA(lo_alv)
        CHANGING
          t_table      = gt_kep_alv[].

There is a workaround with the "full screen" mode : copy the standard GUI status (SALV_TABLE_STANDARD of program SAPLSLVC_FULLSCREEN), add a static button, and communicate the GUI status at runtime by calling LO_ALV->SET_SCREEN_STATUS( ... )

Take a look at program: SALV_DEMO_TABLE_EVENTS, you will know how to define your own function with anykind of screen mode
