Sequential access on CDHDR table

How to improve this query on CDHDR which leads to Sequential access on CDHDR table so that it can improve performance, or is there any other means which i can achieve better performance on CDHDR?
the query as follows:
SELECT objectclas objectid changenr FROM cdhdr INTO TABLE it_cdhdr
WHERE changenr > changenr1 AND ( objectclas = 'VERKBELEG' ).
Thnaks in Advance

Hi Ramada!
Your 2nd index (with change number) has no MANDT field - maybe this is the reason it's not used. Also a combination of change number and object class can be better; you might give it a try.
But in general there is no good way to select the CDHDR for changes done since xxx (change number or date / time).
Of course it's database optimizer decision, but likely you and up all the time with sequential read accesses -> it will be slow in production.
So I gave you a hint how to change the program design a little bit - from business process point of view, this shouldn't be a difference. But if you change from CDHDR to BDCP(S), then you can select changes much faster (usually in a few seconds, even for >100.000 entries).

Christian

CDHDR table query taking long time

Hi all,
Select query from CDHDR table is taking long time,in where condition i am giving OBJECTCLASS = 'MAT_FULL' udate = sy-datum and langu = 'EN'.
any suggestion to improve the performance.i want to select all the article which got changed on current date
regards
shibu

This will always be slow for large data volumes, since CDHDR is designed for quick access by object ID (in this case material number), not by date.
I'm afraid you would need to introduce a secondary index on OBJECTCLAS and UDATE, if that query is crucial enough to warrant the additional disk space and processing time taken by the new index.
Greetings

Archiving MM_SPSTOCK Issues with CDHDR Table

We're executing a number of small variants and in some cases it starts to read the CDHDR table sequentially and the job has to be canceled or eventually terminates. Also, in these cases it holds locks and the transaction MIGO fails and batch GR processes terminates. The sequential reading of CDHDR happens if we run one or multiple jobs of MM_SPSTOCK..
Anybody encounter the sequential read of CDHDR and/or the locking issues?
Any help will be appreciated.
Thanks.
Soyab

No I never faced this issue.
Make sure that you always have the most recent OSS notes applied before you start archiving of any archiving object.
For performance issues see OSS Note 548661 - Composite SAP note: Archive object MM_SPSTOCK

View for CDPOS & CDHDR tables

Hi all,
I am developing a report for which I am fetching fields from CDPOS & CDHDR tables (both r cluster tables). when i run st05, it fetches values from a cluster table CDCLS which takes most of the database time.
Is there any view for CDPOS & CDHDR tables?
How to find the views for cluster tables?
Thanx in advance.
Vijay.

hi,
check this code,
here i used function module to get details of cdhdr,cdpos.

Logical database vs direct access of database table

Hi
I have created a FI report. I am trying to get data from large FI tables like BSAK, BSEG, BKPF, RSEG. eventhough there are 10 records as per my criteria, system is taking morethan an hour time even in background processing. This may be becaz of lot of conditions that I am applying to filter the data. But still trying to improve the performance
For fetching data which is the better way for getting optimum performance of the report.
a) directly fetching data from database tables
b) using logical database collecting data into an itab
regards,
mallik

Hi,
If you are accessing the database tables more than once with different criteria then definetly it will take more time. In such case write only one Select statement on the table and get all the required data into an internal table and then process this internal table as per your logic.
Use of LDBs is definetly faster but filter conditions might not match with your filter conditions. In such case direct access of database table is preferable but as i said in above paragraph.
thanks,

How to Divert the changes to cdhdr table instead of dbtablog?

Hai everybody.
I am new to this forum. i got a job in abap recently. The below is my requirement.I want solution for this one. Anybody plz help me.
I am having ztransaction.
The change logs already were captured in DBTABLOG for table ZWPRFRUND (in transaction ZWPG).
The only report which is currently used to get the change logs is RSVTPROT
Now my requirement is,
we need to display the change logs in the form of ALV.
We should divert the changes to CDHDR table instead of DBTABLOG, then we can use the RSSCD100 to display change logs.
The Important items for the change LOG needed in case of changes to table in ZWPG are,DATE ,TIME,USER,FIRST NAME,FILED NAME,OLD VALUE,NEW VALUE
The above fields need to be displayed in the grid. In the above list FIELD NAME denotes any field of the table in the transaction in ZWPG
Thanks & Regards,
Sujatha.T.

Check out my post in this thread:
How to record add-on table change logs?
You need to define a change document type and generate relevant code for this.

How to Access the XI_AF_MSG table

Hi Experts,
I request you to please let meknow that how can I access the different JAVA tables like XI_AF_MSG table or the AUDIT tables.
Actualy my requirement is to trace the audit log for a particular message ID in the Adapter Engine.This audit trace is not same as the audit log that found in the PI7.0 Runtime WorkBench.For exmaple.--
a message failed in the adapter engine after successfuly processed from PI Integration Engine. Now I want to trace the USERID by whom the message is resent or canceled.
please let me know how can I achive this and how can I access the different tables in JAVA layer.
Thanks
Sugata Bagchi Majumder

These 3 are the tables that are for XI Adapter in ABAP Stack.
SWFRXICNT
SWFRXIHDR
SWFRXIPRC
You can also try the following tables.
SXMSAEADPMOD                   XI: Adapter and Module Information
SXMSAEADPMODCHN                XI: Adapter Module Chains
SXMSAEAGG                      XI: Adapter Runtime Data (Aggregated)

Sequential Access Problem - Nothing is being written to file.

Okay, quick introduction. I am a student and am in an intro Java class. I am understanding most of it; however, I am having one issue with an exercise that I am working on.
Here is the purpose:
To create a simple car reservation application that stores the reservation information in a sequential access file.
In the code what I need to happen is when the user clicks the Reserve Car button, the application needs to first check to see if there are cars already reserved for that day (there is a limit of 4 which is taken care of in the While statement). If the file content is null, it skips this while first.
If the content is null, then I need to open the file for writing, which is taken care of using FileWriter. The program is then to write the date information using the currentDate variable created before the while statement. Next, it is supposed to write the name entered and display a message box stating that the car has been reserved (which it does display).
However, I can add an infinate amount of reservations without getting the error message box stating that the max has been reached. So, I checked the reservations.txt file (which was intially created as a blank file) and I see that nothing at all is getting written to it. Here is the code, can anyone offer any insight into what I am missing. I am not getting any compliation or run-time errors, so I am sure this is just a simple problem I am overlooking. Thanks!

Thank you. Sorry about all the code. I have never posted in this forum before and was unsure what all you needed.
This was the problem though. Right after I posted my question, I went back and looked at the code over again and realized that I left that part out! I added it in and it works perfectly. I came back to update my post but you had already answered it!
I really appreciate the quick response.

CDHDR table is not updated after execution of transaction CK 24

Hi Experts ,
I am Triggering my workflow from for CK 24 transaction based on the change document entry from CDHDR table , once the CK24 transaction executes .
Now the problem is after execution of the CK24 transaction now its not updating the table CDHDR, which was happening before .
Note: No customization has been made which can affect this updation .
Can any body please guide me on this , why the standard table is not being updated now with the change document entries .
Regards
Sarmistha

You can use following FMs
CHANGEDOCUMENT_READ_HEADERS Change document: Read change document header
CHANGEDOCUMENT_READ_POSITIONS Change document: Read change document items
IN CDPOS you have to give the same thing as CDHDR. You have to search with the respective Object class and provide the Object Id(Key fields like Document number). Another thing you will also get the change document number from the transaction itself from which you are change the Document.
Thanks
