Seelct query time out for single region

Question

Hi ,
I am currently facing a problem with a report .The problem is in a select query.The report runs successfully when it is run for only more than 1 state but when it is run for single state then it times out.The select query is as given below.
SELECT avbeln eposnr bvbtyp aerdat akunnr ckunnr d~regio
           ewerks aernam dname1 afaksk b~cmgst
           INTO TABLE t_block
           FROM vbak AS a
           INNER JOIN vbuk AS b
           ON bvbeln = avbeln
           INNER JOIN vbpa AS c
           ON cvbeln = avbeln
           INNER JOIN kna1 AS d
          ON dkunnr = akunnr                             
           ON dkunnr = ckunnr                             
           INNER JOIN vbap AS e
           ON evbeln = avbeln
               WHERE a~faksk IN faksk
                 AND a~vkorg = vkorg
                 AND a~vtweg IN vtweg
                 AND a~spart IN spart
                 AND a~vkbur IN vkbur
                 AND a~vkgrp IN vkgrp
                 AND a~kunnr IN kunnr
                 AND a~ernam IN ernam
                 AND a~erdat IN erdat
                 AND a~vbeln IN vbeln
                 AND a~vbtyp IN vbtyp
                 AND b~spstg IN ('A','B','C')
                 AND ( b~fsstk NE space
                      OR b~cmgst NE space )
                 AND b~abstk NE 'C'
                 AND c~kunnr IN s_kunwe
                 AND c~parvw = 'WE'
                 AND d~regio IN s_regio.
Please let me know if you require any more information.
s_regio is the select option for state.Also I feel that for KUNNR the On conditon might cause soem problem becasue it does not involve key fields.
thanks,

hi ds,
separate the select in several selects. The inner join is not always the best solution.
take
data : ivbak type table of vbak,
   field symbols : <xvbak>
select +++ into corresponding fields of table ivbuk
          from vbuk
          where
select +++ into corresponding fields of table ivbak
         form vbak
         for all entries in ivbuk
         where vbeln eq ivbuk-vbeln ...
select ...
if you want to have one internal table then do it with a loop.
loop at ivbak assigning <xvbak>
read table ikna1 with key kunnr = <xvbak>-kunnr.
loop at ivbap whee vbeln = <xvbak>-vbeln.
itab..= vbak..
? move corresponding ?
append itab.
endloop.
endloop.
that will not cause a time-out.
if you want a verry quick program - use tables without heading lines and field symbols with loops with assigning.
It is more to write but the effect is verry good.
