Report execution takes long time

Question

Dear all,
we have a report which takes long time to exceute due to select statement.. here is the code..
SELECT vkorg vtweg spart kunnr kunn2 AS division FROM knvp
    INTO CORRESPONDING FIELDS OF TABLE hier
    WHERE kunn2 IN s_kunnr
    AND   vkorg EQ '0001'
    AND   parvw EQ 'ZV'.
    l_parvw = 'WE'.
SORT hier.
* select all invoices within the specified invoice creation dates.
  CHECK NOT hier[] IS INITIAL.
  SELECT vbrk~vbeln vbrk~fkart vbrk~waerk vbrk~vkorg vbrk~vtweg vbrk~spart vbrk~knumv
         vbrk~konda vbrk~bzirk vbrk~pltyp vbrk~kunag vbrp~vbeln vbrp~aubel vbrp~posnr
         vbrp~fkimg vbrp~matnr vbrp~prctr vbpa~kunnr
         vbrp~pstyv vbrp~uepos
         vbrp~kvgr4  vbrp~ean11          
    INTO CORRESPONDING FIELDS OF TABLE it_bill
    FROM vbrk INNER JOIN vbrp ON vbrp~vbeln = vbrk~vbeln
              INNER JOIN vbpa ON vbpa~vbeln = vbrk~vbeln
    FOR ALL entries IN hier
    WHERE (lt_syntax)
    AND   vbrk~vbeln IN s_vbeln
*    AND   vbrk~erdat IN r_period
    AND   vbrk~fkdat IN r_period       
    AND   vbrk~rfbsk EQ 'C'
    AND   vbrk~vkorg EQ hier-vkorg
    AND   vbrk~vtweg EQ hier-vtweg
    AND   vbrk~spart EQ hier-spart.
Can anyone say about how to reduce the execution time.?

Hi
first of all never use move corressponding.
Rather you should declare a work area for table hier.
select values into the work area and then append that workarea into the table hier.
In case of for all entries include all the primary keys in the selection and for the keys which are of no use declare constants with initial valules like:
'prmkey' is a primary field for table 'tab1' .
Constants: field1 type tab1-prmkey value initial.
and then in your where condition write.
prmkey GE field1.
I hope it is clear to you now.
Thanks
