hi,

i did a development for alv report in object oriented .. but OO alv hotspot not work .

class lcl_report definition.

public section.

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

* Final Output Table

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

    methods:generate_output,

             handle_hotspot_click FOR EVENT hotspot_click OF cl_gui_alv_grid " hotspot

                                 IMPORTING e_row_id   e_column_id es_row_no.

endclass.

class lcl_report implementation.

method: generate_output.

*****hotspot

data: lr_columns type ref to cl_salv_columns,

lr_column type ref to cl_salv_column_table.

lr_column ?= lr_columns->get_column( 'MATNR' ).
lr_column->set_cell_type( if_salv_c_cell_type=>hotspot ).

endmethod.

METHOD handle_hotspot_click.

PERFORM f_event_hotspot_click USING e_row_id e_column_id es_row_no.

ENDMETHOD.

FORM f_event_hotspot_click USING fp_row_id     TYPE lvc_s_row

                                  fp_column_id   TYPE lvc_s_col

                                  fp_row_no      TYPE lvc_s_roid.

    CLEAR: gs_final.

    READ TABLE gt_final INTO gs_final INDEX fp_row_no-row_id.

    IF sy-subrc EQ 0.

       if fp_column_id = 'MATNR'.

      SET PARAMETER ID 'MAT' FIELD gs_final-matnr.

      CALL TRANSACTION 'CS03' AND SKIP FIRST SCREEN.

    ENDIF.

endif.

ENDFORM.

start-of-selection.

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

data: lo_report type ref to lcl_report.

DATA: g_grid TYPE REF TO cl_gui_alv_grid,

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 to Set PF-Status, Header and Footer

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

    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

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.
