Um mean to say u want to auto-refesh ur ALV list? If it is then try this sample code...

REPORT z_alv_auto_refresh.

TYPE-POOLS: slis. " ALV Global Types

DATA :

gt_user LIKE uinfo OCCURS 0 WITH HEADER LINE. " User info in SM04

----

START-OF-SELECTION.

PERFORM f_read_data.

PERFORM f_display_data.

----

Form F_LIRE_DATA

----

FORM f_read_data.

REFRESH gt_user.

Get User's info

CALL FUNCTION 'THUSRINFO'

TABLES

usr_tabl = gt_user.

Wait in a task

PERFORM f_call_rfc_wait.

ENDFORM. " F_READ_DATA

----

Form F_DISPLAY_DATA

----

FORM f_display_data.

DEFINE m_sort.

add 1 to ls_sort-spos.

ls_sort-fieldname = &1.

append ls_sort to lt_sort.

END-OF-DEFINITION.

DEFINE m_event_exit.

clear ls_event_exit.

ls_event_exit-ucomm = &1.

ls_event_exit-after = 'X'.

append ls_event_exit to lt_event_exit.

END-OF-DEFINITION.

DATA :

ls_layout TYPE slis_layout_alv,

lt_sort TYPE slis_t_sortinfo_alv,

ls_sort TYPE slis_sortinfo_alv,

lt_event_exit TYPE slis_t_event_exit,

ls_event_exit TYPE slis_event_exit.

Build Sort Table

m_sort 'ZEIT'.

Build Event Exit Table

m_event_exit '&NTE'. " Refresh

ls_layout-zebra = 'X'.

ls_layout-colwidth_optimize = 'X'.

CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'

EXPORTING

i_callback_program = sy-cprog

i_callback_user_command = 'USER_COMMAND'

is_layout = ls_layout

i_structure_name = 'UINFO'

it_sort = lt_sort

it_event_exit = lt_event_exit

TABLES

t_outtab = gt_user.

ENDFORM. " F_DISPLAY_DATA

*----

FORM USER_COMMAND **

*----

FORM user_command USING i_ucomm TYPE syucomm

is_selfield TYPE slis_selfield. "#EC CALLED

CASE i_ucomm.

WHEN '&NTE'.

PERFORM f_read_data.

is_selfield-refresh = 'X'.

SET USER-COMMAND '&OPT'. " Optimize columns width

ENDCASE.

ENDFORM. " USER_COMMAND

----

Form F_CALL_RFC_WAIT

----

FORM f_call_rfc_wait.

DATA lv_mssg(80). "#EC NEEDED

Wait in a task

CALL FUNCTION 'RFC_PING_AND_WAIT' STARTING NEW TASK '001'

PERFORMING f_task_end ON END OF TASK

EXPORTING

seconds = 5 " Refresh time

busy_waiting = space

EXCEPTIONS

RESOURCE_FAILURE = 1

communication_failure = 2 MESSAGE lv_mssg

system_failure = 3 MESSAGE lv_mssg

OTHERS = 4.

ENDFORM. " F_CALL_RFC_WAIT

----

Form F_TASK_END

----

FORM f_task_end USING u_taskname.

DATA lv_mssg(80). "#EC NEEDED

Receiving task results

RECEIVE RESULTS FROM FUNCTION 'RFC_PING_AND_WAIT'

EXCEPTIONS

RESOURCE_FAILURE = 1

communication_failure = 2 MESSAGE lv_mssg

system_failure = 3 MESSAGE lv_mssg

OTHERS = 4.

CHECK sy-subrc EQ 0.

SET USER-COMMAND '&NTE'. " Refresh

ENDFORM. " F_TASK_END

If u want normal refresh based on clicking on a button then follow these steps:

1. Pass the subroutine name for event user_command to ALV list like:

CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'

EXPORTING

i_callback_program = sy-cprog

i_callback_user_command = 'USER_COMMAND'

is_layout = ls_layout

i_structure_name = 'UINFO'

it_sort = lt_sort

it_event_exit = lt_event_exit

TABLES

t_outtab = gt_user.

2. In the routine USER_COMMAND trap the fcode and set the refesh field.

*----

FORM USER_COMMAND **

*----

FORM user_command USING i_ucomm TYPE syucomm

is_selfield TYPE slis_selfield. "#EC CALLED

CASE i_ucomm.

WHEN 'ABCD'.

is_selfield-refresh = 'X'.

ENDCASE.

ENDFORM. " USER_COMMAND

3. Attach custom pf-status and there define a button with fcode

ABCD.

So that whenever u press this button user_command routine will get called and ALV list get refreshed.

Joy.
