Hi Sreehari,
Write your Select query inside  IF callcontrol-step = 'DISP'.
Use below code.
*Types
  TYPES: BEGIN OF l_ty_tab,
         lifnr TYPE lifnr,
         END OF l_ty_tab.
  DATA: l_t_tab TYPE TABLE OF l_ty_tab,
        l_wa_tab TYPE l_ty_tab,
        l_wa_recordtab TYPE seahlpres.
*Before displaying hitlist
  IF callcontrol-step = 'DISP'.
    REFRESH: record_tab[],l_t_tab[].
SELECT LIFNR FROM lfa1 INTO TABLE l_t_tab WHERE lifnr LIKE '1%'.
IF NOT l_t_tab[] IS INITIAL.
*Pass hitlist to standard table record_tab
    LOOP AT l_t_tab INTO l_wa_tab.
      l_wa_recordtab-string = l_wa_tab.
      APPEND l_wa_recordtab TO record_tab.
      clear l_wa_recordtab.
    ENDLOOP.
  ENDIF.
  ENDIF.
