Time out error

Former Member — Tue, 26 Aug 2008 08:17:35 GMT

Hi All,

The selection query with the join statement is taking too long time .

define d_select_bfo.

select b_{bukrs b}gjahr b_{belnr b}gsber b_{prctr f}blart f~bldat

from &1 as b

inner join BKPF as f

on b_{bukrs = f}bukrs

and b_{belnr = f}belnr

and b_{gjahr = f}gjahr

into table itb_selglob_tmp

where b~bukrs in s_bukrs

and b~gjahr in s_gjahr

and b~belnr in s_belnr

and f~blart in w_blart

and ( b~gsber in l_gsber

or b~prctr in l_prctr ).

end-of-definition.

&1 = BFOD_A.

This query i have changed to

select bukrs belnr gjahr gsber prctr from &1

into table itb_bfod_a

where bukrs in s_bukrs

and belnr in s_belnr

and gjahr in s_gjahr

and ( gsber in l_gsber or prctr in l_prctr ).

if not itb_bfod_a[] is initial.

sort itb_bfod_a by bukrs belnr gjahr.

select bukrs belnr gjahr blart bldat

from bkpf into table itb_bkpf

for all entries in itb_bfod_a

where bukrs = itb_bfod_a-bukrs

and belnr = itb_bfod_a-belnr

and gjahr = itb_bfod_a-gjahr

and blart in w_blart.

This query also is taking too long time..

Could you please help me out on this issue

i am working on 4.C version....

Thanks in advance

Dont use joines...Because join and all performance issue...

so u need to use loop and read statement..So it avoid the timings

Joins are not the sole issue to this. So do not just assume you know the answer.

I would first try reading BKPF table first. This will greatly reduce the number of records based on the document type field.

Hi Sudhakar,

In my opinion, your second option is better ( for all entries ).

If it takes a long time, this is also because your are retrieving data in tables that are among the hugest table in SAP.

What you can try is to restrict on criteria like BLART, ...etc

Hope this helps,

If its a time out error...go for optimization techniques..

1) split the joins

2) give approrpiate where conditions

3)give the where clause as of in secondary index( if any )

4) if no remedy execute in background

Don't believe the simplistic "use for all entries".

Your join condition between BFOD_A and BKPF looks fine. If the selection ranges are empty when the select is executed, it will run a long time no matter what.

In order to use the secondary index on BKPF-BLART (in case you're dealing with just one document type) you must also select by B~BSTAT = space. Try to add this to the JOIN select statement.

Also, S_BUKRS should have maximum one value.

Your select query looks fine even using For all entries will hardly increase performance, it is just becouse of high volume of data that it is giving time out

Execute the program in background or talk to basis gyes to increase the time slice for the program so that it can be executed in forgraound
