Hi,
Just copy paste this code, activate and test.
INNER JOIN.
TYPES: BEGIN OF  t_vbak,
             vbeln TYPE vbeln,
             END OF t_vbak.
TYPES: BEGIN OF t_vbap ,
       vbeln TYPE vbeln_va,
       posnr TYPE posnr_va,
       END OF t_vbap.
DATA: it_vbak TYPE STANDARD TABLE OF t_vbak.
DATA: wa_vbak TYPE t_vbak.
DATA: it_vbap TYPE STANDARD TABLE OF t_vbap.
DATA: wa_vbap TYPE t_vbap.
select-options:  s_vbeln for wa_vbak-vbeln.
SELECT avbeln bposnr INTO table it_vbap FROM vbak AS a
                            INNER JOIN vbap AS b ON
                            avbeln = bvbeln WHERE a~vbeln in s_vbeln.
loop at it_vbap into wa_vbap.
WRITE:/ wa_vbap-vbeln, wa_vbap-posnr.
endloop.
LEFT OUTER JOINT.
SELECT avbeln bposnr INTO table it_vbap FROM vbak AS a
                             left outer join vbap AS b ON
                             avbeln = bvbeln WHERE a~vbeln in s_vbeln.
loop at it_vbap into wa_vbap.
WRITE:/ wa_vbap-vbeln, wa_vbap-posnr.
endloop.
DIFFERENCE BETWEEN INNER AND LEFT OUTER JOIN.
With respect to above example,
INNER JOIN will fetch all those datas with reference to VBAK in VBAP.
LEFT OUTER JOIN will also fetch all those datas with reference to VBAK in VBAP. But it will also fetch those data which are in VBAK, But not in VBAP.
hope this helps.
