Hi Sagar,

1. Check out if ur PF STATUS is activated.

2. Debug and check if UCOMM is BASIS

Dont pass sy-repid directly to REUSE_ALV_LIST_DISPLAY. Copy it into another variable and then pass it.

data v_repid type sy-repid.

v_repid = sy-repid.

CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'

EXPORTING

i_callback_program = v_repid

I_callback_user_command = 'USER_COMMAND' "see FORM

i_callback_pf_status_set = 'SET_PF_STATUS' "see FORM

it_fieldcat = vt_fieldcat

TABLES

t_outtab = itab.

IF sy-subrc <> 0.

ENDIF.

when u call z PF-STATUS then u call should be like this

form z_pf_status using extab type slis_t_extab.

data i_extab type slis_t_extab with header line.

i_extab[] = extab[].

append '&POST' to i_extab.

set pf-status g_statu_07.

Refer this code

http://www.sapdevelopment.co.uk/reporting/alv/alvgrid_enhanced.htm

http://www.sapdevelopment.co.uk/reporting/alv/alvgrid.htm

make sure taht the FCODE used by you in the screen painter is 'BASIC'.

If that is fine as of now instead of calling a wndow call a transcation and se to figure out the problem.

Hi Sagar,

better you use the event-handler for the ALV-Grid.

see this code and look into the example BCALV_GRID_0*

Data declaration:


CLASS application DEFINITION DEFERRED.
DATA:  event_receiver TYPE REF TO application,

Methods in your program


             handle_toolbar
               FOR EVENT toolbar OF cl_gui_alv_grid
                  IMPORTING e_object e_interactive,

             handle_user_command
               FOR EVENT user_command OF cl_gui_alv_grid
                  IMPORTING e_ucomm
             .


METHOD handle_toolbar.

    DATA: ls_toolbar  TYPE stb_button.

    CLEAR ls_toolbar.
    MOVE 3 TO ls_toolbar-butn_type.
    APPEND ls_toolbar TO e_object->mt_toolbar.

    CLEAR ls_toolbar.
    MOVE 'ENTRY_ACCEPT' TO ls_toolbar-function.
    MOVE ICON_BOOKING_OK TO ls_toolbar-icon.
    MOVE ' your text'(112) TO ls_toolbar-text.
    MOVE ' ' TO ls_toolbar-disabled.
    APPEND ls_toolbar TO e_object->mt_toolbar.

    CLEAR ls_toolbar.
    MOVE 3 TO ls_toolbar-butn_type.
    APPEND ls_toolbar TO e_object->mt_toolbar.

    CLEAR ls_toolbar.
    MOVE 'ENTRY_REFUSE' TO ls_toolbar-function.
    MOVE ICON_BOOKING_STOP TO ls_toolbar-icon.
    MOVE ' your text'(112) TO ls_toolbar-text.
    MOVE ' ' TO ls_toolbar-disabled.
    APPEND ls_toolbar TO e_object->mt_toolbar.
  ENDMETHOD.
*-------------------------------------------------------------------
METHOD handle_user_command.

  CASE e_ucomm.
    WHEN 'ENTRY_ACCEPT'.  CALL SCREEN 200 STARTING AT 10 5.
    WHEN 'ENTRY_REFUSE'.  CALL SCREEN 300 STARTING AT 10 5.

  ENDCASE.

ENDMETHOD.

Code after the creation of the container for the ALV-Grid


    CREATE OBJECT event_receiver.
    SET HANDLER event_receiver->handle_user_command FOR alv_list1.
    SET HANDLER event_receiver->handle_toolbar FOR alv_list1.

pleases look into the SAP examples described above, for detailed information

Re: Button action in ALV

Former Member — Tue, 13 Feb 2007 09:57:38 GMT

CASE UCOMM.
