there is event called DATA_CHANGED

search SDN, there are a lot of post related to this.

but DATA_CHANGED is triggered only byF8(refresh) button.

you can also call the data changed event from USER_COMMAND event.

Hi Kiran, <li> The below code is more than enough. It works for your requirement. <li>Define events

DATA: it_events TYPE slis_t_event,
           wa_event like line of it_events.

<li>Fill events like below.

wa_events-name = 'PF_STATUS_SET'.
wa_events-form = 'PF_STATUS_SET'.
append wa_events to it_events.
clear   wa_events.
wa_events-name = 'USER_COMMAND'.
wa_events-form =  'USER_COMMAND'.
append wa_events to it_events.
clear   wa_events.

<li>Set pf status like below.


FORM PF_STATUS_SET USING RT_EXTAB TYPE SLIS_T_EXTAB.
 SET PF-STATUS 'STATUS' EXCLUDING rt_extab.
"When you set pf-status using above statement, you dont see ALV toolbar. To get back all the tools copy status of the any "program status which is using ALV in SE41 transaction code to your program with status you mentioned here.
"Program :SAPLKKBL
"status    :STANDARD_FULLSCREEN
ENDFORM.

<li>Use USER_COMMAND event like below


*&---------------------------------------------------------------------*
*&      Form  USER_COMMAND
*&---------------------------------------------------------------------*
 FORM USER_COMMAND USING R_UCOMM LIKE SY-UCOMM RS_SELFIELD TYPE SLIS_SELFIELD.

    RS_SELFIELD-REFRESH = 'X'. "Set this one. It refreshes internal table data with new values
  ENDIF.
ENDFORM.                    "USER_COMMAND

<li>Call function module like below


    CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'
         EXPORTING
              i_callback_program = program
              it_fieldcat        = it_fieldcat
              it_events          = it_events
         TABLES
              t_outtab           = i_mard.
