Authorization restriction for executing the ABAP queries

Question

Hi
In ABAP queiries how the restriction can be done for where users should not execute /authorized
of other plant or company code - Projects/ WBS/NWA and its related components. I tried the following methods but not working - seems something is missing .
method 1) restricting based on the profit center ( free coding )
AUTHORITY-CHECK OBJECT 'C_PRPS_PRC'
         ID 'PRCTR' FIELD PROJ-PRCTR
         ID 'PS_ACTVT' FIELD '02'.
(or)
method 2 -(free coding)
*---Authorization for Company code entered by the users.
*---This code will restrict users to see data for company
*---codes which they are not authorized to.
*---Select all the company codes based upon selection entered by the
*---user
SELECT bukrs
   FROM t001
   INTO TABLE li_bukrs
  WHERE bukrs IN z_bukrs.
IF sy-subrc EQ 0.
*---Clear Screen variable for Company code
   CLEAR z_bukrs.
   REFRESH z_bukrs.
*---Filter and prepare Select options for Company code table to be
*---passed to query. Table will only have values of company codes he is
*---authorized to for display.
   LOOP AT li_bukrs INTO lwa_bukrs.
     AUTHORITY-CHECK OBJECT 'F_BKPF_BUK'
                       ID 'BUKRS' FIELD lwa_bukrs
                       ID 'ACTVT' FIELD '03'.
     IF sy-subrc = 0.
       z_bukrs-sign = 'I'.
       z_bukrs-option = 'EQ'.
       z_bukrs-low = lwa_bukrs.
       z_bukrs-high = space.
       APPEND z_bukrs.
     ELSE.
       lv_flag = 'X'.
     ENDIF.
   ENDLOOP.
*---Give warning message to the user in case he is not authorized to see
*---data for all the company codes that he has entered.
   IF lv_flag = 'X'.
     MESSAGE ID 'ZF_MSS_FNG' TYPE 'W' NUMBER '015'.
   ENDIF.
ENDIF.
Just make sure that Z_BUKRS field is available in selection tab.
Also, declare below mentioned variables in INITIALIZATION.
DATA: li_bukrs TYPE TABLE OF bukrs,
       lwa_bukrs TYPE bukrs,
       lv_flag TYPE c.
Kindly help if there is missing anything on the above or is there any other alternative.
