How to get the open order quantity for a material

Question

Hi All,
We need to get the open order quantity for materials. At present we are using the following logic...
SELECT VBAKVBELN VBAPPOSNR VBAP~KWMENG                 
    INTO TABLE IT_VBAP                                     
  FROM VBAP
  INNER JOIN VBAK ON VBAKVBELN   = VBAPVBELN             
  INNER JOIN VAPMA ON VAPMAVBELN = VBAPVBELN
                  AND VAPMAPOSNR = VBAPPOSNR
  INNER JOIN VBUP ON VBUPVBELN = VBAPVBELN
                 AND VBUPPOSNR = VBAPPOSNR
WHERE VAPMA~MATNR = IT_OUTPUT-MATNR
   AND VAPMA~WERKS = IT_OUTPUT-WERKS
    AND VBAK~AUART  IN S_AUART                        
     AND VBUP~GBSTA NE 'C'.     
But the Query takes quite a long time as it does a full range scan on all the tables. Is there any way the query can be improved, may be by creating an index etc? Or is there anyother way by which i can get the required data?
Any input is appreciated.
Regards
Brain.
