Purchase requisition and cost center authorization check

Question

Hi all,
in a R/3 4.7, I need to check the cost center (or profit center) when managing (create/modify/view) purchase requisitions.
I have not found any auths object which perform this check.
Any idea ?
A BADI seems to be he only solution, inserting an authorizaton check.
Thanks
Andrea

Hi
use the BADI in SE18 Tcode
ME_REQ_POSTED
implement this and use
the Method POSTED has the parameter IM_EBKN which has KOSTL field
this will work
see the sample code for this BADI
BAdI Name: ZPUR_RFQ (Implementation name) Purchase Requisitions
Definition Name: ME_REQ_POSTED
Interface Name : IF_EX_ME_REQ_POSTED
Implementing Class: ZCL_IM_PUR_REQ
Method :            POSTED
METHOD if_ex_me_req_posted~posted .
  TYPE-POOLS: pgrt.
  DATA: t_txpdat TYPE STANDARD TABLE OF txpdat.
  DATA: s_txpdat TYPE txpdat.
  DATA: t_ident  TYPE pgrt_t_obj_ident.

      SELECT SINGLE  mtart INTO v_mtart FROM mara WHERE matnr = l_s_eban-matnr.
      IF v_mtart EQ 'ZERS' OR v_mtart EQ 'FHMI' OR v_mtart EQ 'UNBW'.
        MESSAGE e000(zm_msg) WITH 'You are not allowed' 'to create PR for stock items'.
      ENDIF.
    ENDIF.
    IF  l_s_eban-knttp NE 'F' OR l_s_eban-pstyp NE '9'.
      IF l_s_eban-knttp NE 'A'.
        IF ( l_s_eban-pstyp NE '9' AND l_s_eban-pstyp NE 'D' )  AND l_s_eban-matnr EQ space.
