HI Ramesh,
             Use your piece of code in the following way in your event, I hope this will solve your remaining 5% of the problem.
DATA : it_fieldvalues TYPE dynpread OCCURS 0 WITH HEADER LINE.
Constant :  c_1000(4) TYPE c VALUE '1000'.
REFRESH it_fieldvalues.
      it_fieldvalues-fieldname = 'S_BURKS-LOW'.
      APPEND it_fieldvalues.
      CLEAR it_fieldvalues.
      it_fieldvalues-fieldname = 'S_BURKS-HIGH'.
      APPEND it_fieldvalues.
CALL FUNCTION 'DYNP_VALUES_READ'
    EXPORTING
      dyname                   = sy-cprog
      dynumb                   = c_1000
      perform_conversion_exits = 'X'
    TABLES
      dynpfields               = it_fieldvalues
    EXCEPTIONS
      invalid_abapworkarea     = 1
      invalid_dynprofield      = 2
      invalid_dynproname       = 3
      invalid_dynpronummer     = 4
      invalid_request          = 5
      no_fielddescription      = 6
      invalid_parameter        = 7
      undefind_error           = 8
      double_conversion        = 9
      stepl_not_found          = 10
      OTHERS                   = 11.
  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.
Now this internal table <b> it_fieldvalues</b> will automatically contain low and high value for s_burks.You need to read this table and put your logic accordingly.
Please award points if helpful.
