Hi,

Use

SET HANDLER lo_report->handle_hotspot_click  FOR g_grid .

Thanks & Regards,

Can you move the set handler statement before :

lo_report->generate_output( ).

hey,

In my main class, i created the hotspot  method & out put method.. in OO hotspot event shoud create before output method load...   so i did created 2 classes like

***Class definition.

class lcl_event_handler definition deferred.

data: go_event type ref to cl_salv_events_table,

      go_event_handler type ref to lcl_event_handler.

* *********************ALV Class definitions

class lcl_event_handler definition.

  public section.

    methods handle_hotspot_click for event link_click of cl_salv_events_table " hotspot

                                 importing row column.

endclass.

class lcl_report definition.

  public section.

*----------------------------------------------------------------------*

* Final Output Table

*----------------------------------------------------------------------*

    data: o_alv type ref to cl_salv_table.



    methods:generate_output.



  private section.

*----------------------------------------------------------------------*

*----------------------------------------------------------------------*

    methods:  set_pf_status

                     changing

                         co_alv type ref to cl_salv_table, " Default Pf Status



                set_top_of_page

                     changing

                         co_alv type ref to cl_salv_table. ", " Set Top of page

*                set_end_of_page

*                     changing

*                         co_alv type ref to cl_salv_table. " Set End of page


endclass.

class lcl_event_handler implementation.

  method handle_hotspot_click.

    perform f_event_hotspot_click using row column.                "handle_hotspot_click

  endmethod.                    "handle_hotspot_click

endclass.

*Exception Class

    data: lc_msg type ref to cx_salv_msg.

*----------------------------------------------------------------------*

    try.

        call method cl_salv_table=>factory

          importing

            r_salv_table = o_alv

          changing

            t_table      = gt_final.



      catch cx_salv_msg into lc_msg .



    endtry.





    "Get Events

    go_event = o_alv->get_event( ).

    create object go_event_handler.

    set handler go_event_handler->handle_hotspot_click for go_event.

endclass. 

form f_event_hotspot_click  using fp_row         type salv_de_row

                                  fp_column      type salv_de_column.



  clear: gs_final.

  read table gt_final into gs_final index fp_row.

  if sy-subrc eq 0.

    if fp_column = 'MATNR'.

      set parameter id 'MAT' field gs_final-matnr.

      call transaction 'CS03' and skip first screen.

    endif.

  endif.



endform.

try this way
