LEFT OUTER JOIN

Dear experts,

I want to ask about left outer join, the problem is that i used left outer join in my select statement

like below ;

SELECT

     QALS~PRUEFLOS

     QALS~CHARG

     QALS~KTEXTMAT

     QALS~AUFNR

     QALS~ZZ_TUMANALIZ

     QALS~PLNNR

     QALS~ENSTEHDAT

     QALS~MATNR

     QALS~ENTSTEZEIT

     QALS~OBJNR

     QALS~LAGORTCHRG

     QALS~KDAUF

     MARA~MATKL

     MARA~MTART

     QASR~MERKNR

     QASR~ZEITERSTL

     QASR~CODE1

     QASR~ERSTELLDAT

     QASR~ORIGINAL_INPUT

     QAPP~VORGLFNR

     QAPP~PROBENR

     INTO CORRESPONDING FIELDS OF TABLE ITAB FROM QALS

      INNER JOIN MARA ON QALS~MATNR    EQ MARA~MATNR

      LEFT OUTER JOIN QAPP ON QALS~PRUEFLOS EQ QAPP~PRUEFLOS

      INNER JOIN QASR ON QALS~PRUEFLOS EQ QASR~PRUEFLOS AND

                         QAPP~VORGLFNR EQ QASR~VORGLFNR AND

                         QAPP~PROBENR  EQ QASR~PROBENR

The key field prueflos; sometimes QAPP table or QASR table doesnt contains QALS-Prueflos so,

there is no result.I want to see all QALS lines in ALV report. I am waiting your solutions.Thanks.

Regards.
