hi,
you can get accounting details from  material document in this way.
DATA: BEGIN OF it_rbkp OCCURS 0,
      belnr LIKE rbkp-belnr,
      bldat LIKE rbkp-bldat,
      xblnr LIKE rbkp-xblnr,
      gjahr LIKE rbkp-gjahr,
      awkey LIKE bkpf-awkey,
      END OF it_rbkp.
DATA: BEGIN OF it_bkpf_we OCCURS 0,
      belnr LIKE bkpf-belnr,
      awkey LIKE bkpf-awkey,
      END OF it_bkpf_we.
DATA: BEGIN OF it_mkpf OCCURS 0,
      mblnr LIKE mkpf-mblnr,
      blart LIKE mkpf-blart,
      bldat LIKE mkpf-bldat,
      mjahr LIKE mkpf-mjahr,
      awkey LIKE bkpf-awkey,
      END OF it_mkpf.
  IF NOT it_ekbe[] IS INITIAL.
    SELECT mblnr
           blart
           bldat
           mjahr
           INTO TABLE it_mkpf
           FROM mkpf
           FOR ALL ENTRIES IN it_ekbe
           WHERE mblnr = it_ekbe-belnr
           AND   blart = c_we.
  ENDIF.
  LOOP AT it_mkpf.
    CONCATENATE it_mkpf-mblnr it_mkpf-mjahr INTO it_mkpf-awkey.
    MODIFY it_mkpf TRANSPORTING awkey.
  ENDLOOP.
IF NOT it_rseg[] IS INITIAL.
    SELECT  belnr
            bldat
            xblnr
            gjahr
            INTO TABLE it_rbkp
            FROM rbkp
            FOR ALL ENTRIES IN it_rseg
            WHERE belnr = it_rseg-belnr.
              ENDIF.
  LOOP AT it_rbkp.
    CONCATENATE it_rbkp-belnr it_rbkp-gjahr  INTO it_rbkp-awkey.
    MODIFY it_rbkp TRANSPORTING awkey.
  ENDLOOP.
  IF NOT it_mkpf[] IS INITIAL.
    SELECT belnr
           awkey
           INTO TABLE it_bkpf_we
           FROM bkpf
           FOR ALL ENTRIES IN it_mkpf
           WHERE awkey = it_mkpf-awkey.
  ENDIF.
