Making a query performant

Former Member — Sun, 23 May 2010 06:04:14 GMT

Hi all,

Iam reading data from 2 tables cdhdr,cdpos.

The selection screen contains following inputs from the user

Date,Header BOM material,bom usage(mast-stlan, For Example 8).

select cdhdr~username cdhdr~udate cdpos~changeid cdpos~valuenew
         cdpos~valueold cdpos~tabname cdpos~feldname into CORRESPONDING FIELDS OF TABLE gt_ditab
         from cdhdr inner join cdpos
     on cdhdr~OBJECTCLAS = cdpos~OBJECTCLAS
        and cdhdr~changenr = cdpos~changenr
  where cdhdr~objectclas =
 'stue' and cdhdr~udate in so_date

Is there any more condition I could put in,in the above query so that the query is performant.

Thanks

hello,

You can also add Transaction code in selection condition-

if you know which transaction is adding entries in CDHDR table, also can check maximum entries and should have an idea...

Thanks

Hi,

The additional criteria that can be entered is context dependent & would vary in different cases.

As Krishendu indicated, you can make use of TCODE to specify additional criteria.

However, since you are dealing with change document data, I would recommend you to use the function modules present in the F.group SCD1 & SCD0.
