FETCH is taking lot of time when executing the program

Hi,
A program is lot of time in production though code looks ok.
Only one select statement is there which fetches data from BKPF.
Cost of the statement is as below:
SELECT STATEMENT ( Estimated Costs = 51 , Estimated #Rows = 1 )
       2 TABLE ACCESS BY INDEX ROWID BKPF
         ( Estim. Costs = 51 , Estim. #Rows = 1 )
         Estim. CPU-Costs = 1,938,416 Estim. IO-Costs = 51
         Filter Predicates
           1 INDEX RANGE SCAN BKPF~Z1
             ( Estim. Costs = 51 , Estim. #Rows = 1 )
             Search Columns: 4
             Estim. CPU-Costs = 1,936,841 Estim. IO-Costs = 50
             Access Predicates Filter Predicates
And in Se30 Execution time in Data base is 98.7% and Abap is 1.2%
When I checked the Trace I found that the 2,487,732 & 84720,805 secs is being taken in the FETCH stage.
     27     BKPF               REOPEN               0     SELECT WHERE "MANDT" = '600' AND "GJAHR" = 2003 AND "BUKRS" = '0301' AND "BLART" = 'ZA' AND "BUDAT" = 20030319 AND "STBLG" = ' '
     2,487,732     BKPF               FETCH     406          0
     84,720,805     BKPF               FETCH     377          1403
Can you please let me know what wrong in this? And what can I do to tune this fetch statement?
Regards,
Pooja

Hi,
so we can only use
(MANDT)?
BUKRS
BLART
as access predicates and
STBLG
as filter predicate.
BUDAT schould be part of the access predicates i think.
Watch out for an index where BUDAT can be used as access predicate....
Kind regards,

Difference between DB time OLAP time frontend time when execute the query

hi all,
can you any one explain the difference between DB time, OLAP time, frontend time when execute the query

Each BEx quey form a SQL query which is called query execution plan.
So,
DB Time is the time taken to read the record from data base by the SQL statement.
OLAP time is the time taken to process the calculations/formula involved.
Frontend Time is the time taken to present the output. For ex: while displaying the data in Bex analyser if your query involves a hierarchy, then the presentation time will be more. It also includes the time user taken to enter the query selection input.

Background job is taking lot of time for processing the job.

One background job - which is processing Idocs is processing a job for more than 2000+ seconds.. and completed tho.
But this is happening for the past few days.. is there any way to trouble shoot, or find from any logs of this completed job, to find out why it was taking lot of time for processing.
Can you please tell me the steps of analyzing / trouble shooting why it was taking lot of time daily.

Hi Satish,
Run DB stat from db13 it will improve the performance.
Check number of idocs. You can send part by part, instead of sending huge data.

BDC is not working in when executing the program in background

Hi gurus,
I have a problem that in BDC is not working when i'm executing the upload program in background thru scheduling(SM36) , while it works fine when i execute directly with NO screen display mode

Many transactions behave differently when executed in foreground and background. The fields on the screen may be different.
In transaction SHBD when starting a recording there is a checkbox where you can select 'Simulate Background Mode'. If you do your recording using this option you will get the code suitable for background mode. If you do not select this option you will get a code for foreground mode.
By compairing the two codes you will know the changes required for background mode.
Hope this helps you

Query taking lot of time to execute..

Hi,
I have a very complecated query which I am executing using JDBC. The query has an insert statement. This query takes 15 mins to complete. I'm running the query as stand alone java program. Can some one have some suggestions what is the best way to debug. I need to find out why the query is taking that long. I'm using oracle 10g with sql developer.
ps = con.prepareStatement(query);
ps.setString(1,date);
ps.setString(2,code);
timeStart = System.currentTimeMillis();
ps.executeUpdate();
timeEnd = System.currentTimeMillis();
System.out.println("Time Taken::"+(timeStart -timeEnd)+" ms");
Thanks in advance
Ajoo

Perhaps you should post the query so we can see what you are doing.
In the mean time, try writing a simple update query and run it. If it runs quickly, your original query has problems. If it runs slow, its caused by something other than your original query.
P.S.:
should be:
System.out.println("Time Taken::"(timeEnd -timeStart)" ms");
and not this:
System.out.println("Time Taken::"(timeStart -timeEnd)" ms");

hi,
you can use open cursor to fetch such large number of records and it will reduce the time and its very performnace effective.
a sample code is :
Selection using open cursor
DATA: LWA_OP_SAL_ORD1 TYPE GT_COMTAB.
IF SY-SUBRC = 0.
    OPEN CURSOR C1 FOR
      SELECT VBAP~MATNR
      FROM VBAP INNER JOIN VBAK
      ON VBAPVBELN EQ VBAKVBELN
      FOR ALL ENTRIES IN GIT_VBUK
      WHERE VBAP~VBELN = GIT_VBUK-VBELN AND
            VBAK~VBTYP = 'C'.
    DO.
      CLEAR LWA_OP_SAL_ORD1.
      FETCH NEXT CURSOR C1 INTO CORRESPONDING FIELDS OF LWA_OP_SAL_ORD1.
      IF SY-SUBRC = 0.
        APPEND LWA_OP_SAL_ORD1 TO LI_OP_SAL_OR
enddo.
i think this will help.

I have LR6 running on a Windows machine. Several times when launching the program I'm prompted as if I'm running a trial version, and then have to click a button to register and re-enter my license number. This is getting tedious--what's going on Adobe?

Please rush getting the first patch of updates out--I'm expecting a finished product, not a "beta" version. I don't mind beta testing, but not AFTER I've purchased an upgrade!!

You do not have the properties in the Bookmarks Manager (Library), but you should have it if you right-click a bookmark the Bookmarks Toolbar or in the bookmarks sidebar.
On Mac you probably do not have it if you right-click an item in the Bookmarks menu (this menu is under control of the Mac OS), but I assume that this should work if you click the "Show your bookmarks" button on the Navigation Toolbar that is next to the star to bookmark the current tab and right-click an item in the bookmarks list that opens.

Edited by: Deepak_Hegde on Feb 2, 2012 4:58 PM

Why wouldn't you use standard functionality with *RUN_PROGRAM CURR_CONVERSION?
You'll have to call it multiple times since you want to translate into different currencies, but I think it will still be faster than this script.

Comma Separated Value Taking too Much Time to Execute

Hi,
select ES_DIAGNOSIS_CODE DC from ecg_study WHERE PS_PROTOCOL_ID LIKE 'H6L-MC-LFAN'
The above query returns comma separated value from the above query.
I am using the query below to split the comma separated value but the below query is taking lot of time to return the data.
SELECT
select DC from (
with t as ( select ES_DIAGNOSIS_CODE DC from ecg_study WHERE PS_PROTOCOL_ID LIKE 'H6L-MC-LFAN' )
select REGEXP_SUBSTR (DC, '[^,]+', 1, level) DC from t
connect by level <= length(regexp_replace(DC,'[^,]*'))+1 )
Please suggest me is there any alternative way to do this comma separated value.
Thanks

Hi BluShadow,
I know that this function is fast with varchar2 strings from several years of using it. With CLOBs one may need something faster, but the OP didn't menion CLOBs.
Best regards,
NikolayJust because you perceive it to be fast doesn't mean it's faster than doing it in SQL alone.
For starters you are context switching from the SQL engine to PL/SQL to call it.
Then in your code you are doing this...
select substr(v_str,v_last_break+1, decode(v_nxt_break,0,v_length, v_nxt_break-v_last_break-1)) into v_result from dual;which is context switching back from the PL/SQL engine to the SQL engine for each entry in the string.
Why people do that I don't know... when PL/SQL alone could do it without a context switch e.g.
v_result := substr(v_str,v_last_break+1, case when v_nxt_break = 0 then v_length else v_nxt_break-v_last_break-1 end);So, if you still think it's faster than pure SQL (which is what the OP is using), please go ahead and prove it to us.

Select Command taking a lot of time to execute

Dear Experts,
My below SELECT command taking a lot of time to execute.
      SELECT wid
                   matl_desc
                   INTO TABLE open_wid FROM zwb_table
                   WHERE ( weight2 = 0 OR weight2 IS NULL ).
Table : zwb_table contains around 7 Lacs records. That's why taking a lot of time . I have also Indexed the table zwb_table with field WID & WEIGHT2 . (zwb_table contains only WID as Primary Key Field)
Structure of Internal Table : open_wid ->
                                         wid LIKE zwb_table-wid,

Please suggest me how to Improve the Performance of the above Select command.
Thanks in Advance
JACK

Hi Jack,
you are having morethan 7lack records in z table. it is not good practice fetching all the records into internal table and restricting with where clause in loop statement.
I hope you already created secondary index combination of primary key.
check you select query fetching records based on index you have created in ST05.
Refer below link for your program is using index that you have created.

Background task taking a lot of time to execute

Hi,
There is a background task in my workflow which is taking a lot of time to execute.
I have tested it in dialog mode.. and it works fine.. takes just 2 mins.
Only when the task is executed from background.. it takes about 10 mins.
Is this a config problem? How do I check if it is so?

you could try activating a trace (sql) and see what the differences are,.
you could check if maybe user parameters are influencing this. Or ask your basis team if there are a lot of differences between syystem users and dialog users in terms of resource allocation.
Did you find anything different whilst debugging it?
Kind regards, Rob Dielemans

      AND rpmax = c_max_period.
for both the above table program is taking very less time .... although both the table used in above queries have similar amount of data. And i can not remove the APPENDING CORRESPONDING. because i have to append the data after fetching from the tables. if i will not use it will delete all the data fetched earlier.
Thanks on advanced......

FETCH is taking lot of time when executing the program
