Hi,
If it is list, try using events and then call it in reuse_alv_grid_display.
Sample code from SDN
**events
REFRESH:IT_EVENTS.
CLEAR:X_EVENTS,IT_EVENTS.
X_EVENTS-NAME = SLIS_EV_END_OF_LIST.
X_EVENTS-FORM = 'MODIFY_LIST'.
APPEND X_EVENTS TO IT_EVENTS.
CLEAR X_EVENTS.
END-OF-SELECTION.
  CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'
    EXPORTING
      I_CALLBACK_PROGRAM = SY-REPID
      IT_FIELDCAT        = IT_FIELDCAT
      IT_EVENTS          = IT_EVENTS
    TABLES
      T_OUTTAB           = ITAB
    EXCEPTIONS
      PROGRAM_ERROR      = 1
      OTHERS             = 2.
  IF SY-SUBRC <> 0.
    MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
            WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.
FORM MODIFY_LIST.
data: l_lines type i.
describe table itab lines l_lines.
  L_LINES  = L_LINES + 3.
  "because we have 3 lines extra occupied by lables.
  "if we have header,i mean top of page add the no.of lines
  "how many ever top of page have + 3 for labels.
  DO L_LINES TIMES.
    read table it_chg with key INDEX = sy-index.
    if sy-subrc = 0.
**This code is for reading the out put line
**and modify accordinlg to our requiremnet.
**don't chnage this.
      READ LINE SY-INDEX INDEX SY-LSIND.
      IF SY-SUBRC = 0.
        MODIFY LINE SY-INDEX INDEX SY-LSIND
                   FIELD FORMAT ITAB-NAME INPUT.
      ENDIF.
    ENDIF.
  ENDDO.
ENDFORM.                    "MODIFY_LIST
