Data selection from Table

Question

Hi ,
My requirement is to have Commercial Documents which are not Accounted. So that I've used the following logic.
  SELECT a~vbeln
                 a~vbtyp
                 a~fkdat
                 a~bukrs
         a~kunrg
         SUM( b~netwr )
       FROM vbrk AS a INNER JOIN vbrp AS b
       ON avbeln EQ bvbeln
       INTO ls_bill WHERE a~vbtyp EQ 'M'          AND
                          a~fkdat IN s_fkdat      AND
                          a~bukrs IN s_bukrs      AND
                          a~kunrg IN s_kunrg
                    GROUP BY a~vbeln
                             a~vbtyp
                             a~fkdat
                             a~bukrs
                             a~kunrg.
    l_awkey = ls_bill-vbeln.
    SELECT awkey FROM bkpf INTO l_awkey
                 WHERE awtyp EQ 'VBRK'  AND
                       awkey EQ l_awkey AND
                       bukrs EQ ls_bill-bukrs.
    ENDSELECT.
    IF sy-subrc NE 0.
      APPEND ls_bill TO lt_bill.
    ENDIF.
    CLEAR : ls_bill, l_awkey.
  ENDSELECT.
Is that the above logic for getting data is correct. or  First taking all the entries from VBRK and VBRP table then selecting entries from BKPF and then if any entry of VBRK is not in BKPF then taking that.
