Query optimizaing for performance tune

Question

Hi guys,
              The below  query is taking a lot of time to execute.The main problem is with table S022.This table is going for full table scan everytime  even if we give a lot of selection criteria.So is there any alternate table for S022.In selection screen the mandatory fields are Location,plant and Phase.
SELECT a~aufnr      "Order number
         e~arbpl      "Work center
         e~plnum      "Plaaned order
         b~objnr      "Object number
         a~werks      "plant
         c~charg      "Batch
         d~gamng      "qty
         d~gmein      "UOM
         d~plnbez     "Material
         d~aufpl      "routing no
         d~aprio      "Order priority
         d~fevor      "Responsible planner group/department
         f~aufpl      "Routing no
         f~aplzl      "general counter
         f~vornr      "Phase
         f~arbid      "workcenter
         f~ltxa1      "text
         g~objty      "Object type
         g~stand      " Location
         INTO CORRESPONDING FIELDS OF TABLE t_afpo
          FROM (  (  ( (  ( s022 AS e
                      INNER JOIN aufk AS a ON   aaufnr = eaufnr )
                      INNER JOIN jest AS b ON   aobjnr = bobjnr )
                      INNER JOIN afpo AS c ON   caufnr = aaufnr
                                           AND  awerks = cdwerk )
                      INNER JOIN afko AS d ON   daufnr = caufnr
                      INNER JOIN afvc AS f ON   faufpl   = daufpl
                                           AND  fvornr   = evornr )
                     INNER JOIN crhd AS g ON    garbpl = earbpl
                                               AND gobjid = farbid )
            WHERE    a~werks  IN s_werks
            AND      d~plnbez IN s_matnr
            AND      d~fevor  IN s_fevor
            AND      e~arbpl  IN s_arbpl

Hi,
i would suggest that dont put too many joins in the select statement..
if possible try to put mulitple select statements using "for all entries".
and also join the table only with key fields so that the data fetching will be more faster..
if you are not able to use the key fields try with index fields provided by SAP..
if that is also not working then create Zindex field for the table which is using more time to fetch the data.
