Hi friends,

Can u give me soolution for the below select statement to increase the performance.

SELECT * FROM setleaf WHERE

setclass EQ '0106' AND

subclass IN i_subclass AND

setname LIKE l_setname.

MOVE: setleaf-valsign TO r_pgroup-sign,

setleaf-valoption TO r_pgroup-option,

setleaf-valfrom TO r_pgroup-low,

setleaf-valto TO r_pgroup-high.

APPEND r_pgroup.

CLEAR r_pgroup.

ENDSELECT.

data : it_setleaf type table of setleaf,

st_setleaf type setleaf.

select * from setleaf

into table it_setleaf

where setclass EQ '0106'

and subclass IN i_subclass

and setname LIKE l_setname.

loop at it_setleaf into st_setleaf.

r_pgroup-sign = setleaf-valsign.

r_pgroup-option = setleaf-valoption.

r_pgroup-low = setleaf-valfrom.

r_pgroup-high = setleaf-valto.

append r_pgroup.

endloop.

Select ... Endselect is kinda a select in a loop. so i think the above should be quite efficent.

Mahesh - this is the second time today I have moved your question to the correct forum. Performance questions go in the ABAP Performance and Tuning forum. And try to get a better subject than "performance issue".

Hi,

Check the below code:

data : it_setleaf type standard table of setleaf,
wa_setleaf type setleaf.

data: it_pgroup type standard table of ussel,
wa_pgroup type ussel.

select * from setleaf 
into table it_setleaf
where setclass EQ '0106' 
and subclass IN i_subclass 
and setname LIKE l_setname.

loop at it_setleaf into wa_setleaf.
wa_pgroup-sign = wa_setleaf-valsign.
wa_pgroup-option = wa_setleafvaloption.
wa_pgroup-low = wa_setleaf-valfrom.
wa_pgroup-high = wa_setleaf-valto.
append wa_pgroup to it_pgroup.
clear wa_pgroup.
endloop.

Regards,

Saba

Try this one.


data :
  it_pgroup type standard table of ussel.

select   valsign  as sign
           valoption as option
           valfrom   as low
           valto       as high
           from setleaf 
           INTO CORRESPONDING FIELDS OF TABLE it_pgroup
           where setclass EQ '0106' 
           and subclass IN i_subclass 
           and setname LIKE l_setname.

But actually your original solution was also o.k.

Please check the performance of the WHERE condition which indexes are available, is this

i_subclass filled?

Hi,

please try this one...

data : it_setleaf type standard table of setleaf .

select valsign valoption valfrom valto

from setleaf

into corresponding fields of table it_setleaf

where setclass = '0106'

and subclass = i_subclass

and setname = l_setname.

Use 'EQ' in where clause for first time to get account group / reporting group from setleaf .then pass the same from it_setleaf to other tables .
