    *----


    data : begin of itab occurs 0.

    include structure usr02.

    data : end of itab.

    *----


    START-OF-SELECTION.

    select * from usr02

    into table itab.

    CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

    EXPORTING

    i_program_name = sy-repid

    i_internal_tabname = 'ITAB'

    i_inclname = sy-repid

    EXCEPTIONS

    inconsistent_interface = 1

    program_error = 2

    OTHERS = 3.

    *----


    IMPORTANT

    LOOP AT ALVFC INTO ALVFCWA.

    IF ALVFCWA-FIELDNAME = 'USTYP'.

    ALVFCWA-NO_CONVEXT = 'X'.

    MODIFY ALVFC FROM ALVFCWA.

    ENDIF.

    ENDLOOP.

    Using the OOPS Concepts

    Note that this example uses table ZSFLIGHT. The table is equivalent to the table SFLIGHT.

    Steps:

    Create an executable program (Report)

    Create a screen (100) and place a custom container named ALV_CONTAINER on the screen

    Create a Pushbutton. Give it the text Exit and the functioncode EXIT

    REPORT sapmz_hf_alv_grid .

    TABLES: zsflight.

    *----


    • G L O B A L I N T E R N A L T A B L E S

    *----


    DATA: gi_sflight TYPE STANDARD TABLE OF sflight.

    *----


    • G L O B A L D A T A

    *----


    DATA: ok_code LIKE sy-ucomm,

    g_wa_sflight LIKE sflight.

    • Declare reference variables to the ALV grid and the container

    DATA:

    go_grid TYPE REF TO cl_gui_alv_grid,

    go_custom_container TYPE REF TO cl_gui_custom_container.

    *----


    • S T A R T - O F - S E L E C T I O N.

    *----


    START-OF-SELECTION.

    SET SCREEN '100'.

    &----


    *& Module USER_COMMAND_0100 INPUT

    &----


    MODULE user_command_0100 INPUT.

    CASE ok_code.

    WHEN 'EXIT'.

    LEAVE TO SCREEN 0.

    ENDCASE.

    ENDMODULE. " USER_COMMAND_0100 INPUT

    &----


    *& Module STATUS_0100 OUTPUT

    &----


    MODULE status_0100 OUTPUT.

    • Create objects

    IF go_custom_container IS INITIAL.

    CREATE OBJECT go_custom_container

    EXPORTING container_name = 'ALV_CONTAINER'.

    CREATE OBJECT go_grid

    EXPORTING

    i_parent = go_custom_container.

    PERFORM load_data_into_grid.

    ENDIF.

    ENDMODULE. " STATUS_0100 OUTPUT

    &----


    *& Form load_data_into_grid

    &----


    FORM load_data_into_grid.

    • Read data from table SFLIGHT

    SELECT *

    FROM zsflight

    INTO TABLE gi_sflight.

    • Load data into the grid and display them

    CALL METHOD go_grid->set_table_for_first_display

    EXPORTING i_structure_name = 'SFLIGHT'

    CHANGING it_outtab = gi_sflight.

    ENDFORM. " load_data_into_grid

    Regards

    - Gopi
