Select on KEKO

Former Member — Thu, 11 May 2006 19:26:42 GMT

I have the material number and the plant. What is the most efficient select to get the latest kalnr(costing estimate) based on date. Doing a select-endselect to find the last record is a performance problem.

Current code:

select kalnr kadky

from keko

where matnr = mbew-matnr

werks = werks-low.

endselect.

Suggestions? Thank you.

report zrich_0001.


data: ikeko type table of keko with header line..

parameters: p_matnr type mara-matnr,
            p_werks type marc-werks.


select * from keko into table ikeko
            where matnr = p_matnr
              and werks = p_werks.


sort ikeko descending by kadky.

read table ikeko index 1.


write:/ ikeko-kadky, ikeko-matnr, ikeko-werks, ikeko-LOSGR.

Hello Janet,

Rather than using Select-EndSelect, you can used Select into internal table....which wll be much faster while processing data.

So query will be...

Select Kalnr kadky

into itab1

from keko

where matnr = mbew-matnr

werks = werks-low.

and then you can loop into itab1 if you want to process data.

Cheers,

Nilesh

Or you can do something like this.



report zrich_0001.


data: xkeko type keko .

parameters: p_matnr type mara-matnr,
            p_werks type marc-werks.

select * from keko up to 1 rows into  xkeko
            where matnr = p_matnr
              and werks = p_werks
                  order by kadky descending.

endselect.

write:/ xkeko-kadky, xkeko-matnr, xkeko-werks, xkeko-losgr.

The SELECT... ENDSELECT is a slower method.

You have no keys fields here so your DB engine will be using the INDEX on MATNR.

select Kalnr kadky

into table The_Table

from keko

where matnr = mbew-matnr

werks = werks-low

descending by kadky.

read table The_table index 1.

select single Kalnr kadky into (keko-kalnr, keko-kadky)

from keko

where matnr = mbew-matnr

werks = werks-low

descending by kadky.
