Authorization object for plant on selection-screen

Question

Hi All,
I need to cehck the authorization object for plant on sleection screen..the palnt is select-options.
I have written the code
Declaration of local constants.
  CONSTANTS : lc_i(1)  TYPE c VALUE 'I',
              lc_eq(2) TYPE c VALUE 'EQ'.
  REFRESH : r_werks.
  LOOP AT s_werks.
    IF s_werks-low IS NOT INITIAL.
      AUTHORITY-CHECK OBJECT 'M_MATE_WRK'                "Check if the user has autorization for the plant.
                           ID 'ACTVT' FIELD '03'
                           ID 'WERKS' FIELD s_werks-low.
      IF sy-subrc NE 0.
        r_werks-sign   = lc_i.
        r_werks-option = lc_eq.
        r_werks-low    = s_werks-low.
        APPEND r_werks.
      ENDIF.
    ENDIF.
  ENDLOOP.
  LOOP AT s_werks.
    IF s_werks-high IS NOT INITIAL.
      AUTHORITY-CHECK OBJECT 'M_MATE_WRK'                "Check if the user has autorization for the plant.
                           ID 'ACTVT' FIELD '03'
                           ID 'WERKS' FIELD s_werks-high.
      IF sy-subrc NE 0.
        r_werks-sign   = lc_i.
        r_werks-option = lc_eq.
        r_werks-low    = s_werks-high.
        APPEND r_werks.
      ENDIF.
    ENDIF.
  ENDLOOP.
My doubt is will the authorization will check the plants in between 1001 and 2001..suppose i have pplants 1001,1002,1003,1004,2001..Now will the above code will check for all the plants or only 1001 and 2001 if i specify in the select-options.

Hi Raj
First no need to LOOP AT s_werks and check s_werks-high as it will always be present only once in the table s_werks.
Do this
SELECT werks FROM t001w INTO li_werks
WHERE werks IN s_werks.
LOOP AT li_werks.
*check your authority thing here and fill the range
ENDLOOP.
