Change log table

Hi gurus
In my start rotine how do i use change log table for e.g i want to delete the records where RECORDMODE ='x' HOW can i reference change log table.because when i use the start routine is it only good for active table? becasue all the changed i m getting in changelog table and my dtp i m extracting data from changelog table but i want to delete data from that table how do i refer.
thanks

recordmode is a part of your source_package as well as result_package.
hence you can access it is start routine also.
you can delete the source package where recordmode = 'X'.
but doing so it may result inconsistency in your change log table.
the only concern is be sure what you want to achieve as 'X' is before image ( i.e reverse of new image loaded earlier).

Need suggestion to get data from change log table of ODS.

Hello,
There is a case where i am loading opportunity header data from header ODS and opportunity item data from item ODS in the opportunity cube.
Status (1= OPEN, 2= WON ETC) of the opportunity are available only in header ODS and not in item ODS.
While loading data from header ODS to cube, I am loading it directly but while loading data from item ODS to cube i am using active data table of header ODS as a lookup in the update rule from item ODS to cube. I am selecting status from the active data table of header ODS while loading data from item ODS to cube.
Since active data table will have only after image records, there is some data mismatch in the report as i am selecting data from active data table of header ODS while loading data from item ODS to cube.
I need to select data from Change log in order to get before image also instead of active data table in order to overcome this issue. Is there any way by which i can do selection from Change log instead of active data table as change logs are generated at run time.
Please let me know if you have any suggestions.
Regards,
Sanjay Chaurasia.

Hi,
You can use the changelog table of the DSO.
Right click manage the Header DSO, go to the contents tab and click Change Log table. There you can see the technical name of the Change Log table.
In the update rule Routine, give the tech name of Change log table instead of Active table name.
Hope it helps.

How to find out the top ten Change log tables in BW

I want to know the top ten change log tables in terms of size. Do we have a SAP standard table where we have the following fields : "changlog table name", "number of records" field or "data in size" field.
Regards,
Prashant M J

Hi,
Click on change log table in the ODS/DSO at the top you see the name as /bic* which is the name of the database table which could also be seen at SE11.
If you wana see the requests in this change log use rstsodsrequest
and if you wana see the size in terms of kb, mb DB02 or st04
use the table name /bic* and click on tables and indexes option in history tab
DB02 tells you the sizes of the tables present on database. Incase you are not able to your basis team would help you in that
Thanks and regards

Where to see the images other than change log table

Dear all,
How to view images for extraction's (example Generic ) in DSO without using Change log table.
With Regards,
Baskaran

Hi,
There is no other option other than change log table to view the images.
in PSA..we will get only raw data..i.e...its non other than the data how its posted in source sytem.we can say..this is only copy of source sytem data.
after PSA,if the datasource is DELTA enabled(which can sustain NEW or CHANGED records-here only we get concept of IMAGES),we have to load this data only to DSO.from there after activation of the data,the data can be updated to further data targets only from CHANGE LOG table which can maintain images.
Even further targets are also DSOs,we will have to load from this DSO only.so we can see images only in change log table.
hope this is clear for you.

Delete Entries of Change Log Table

Can any one tell me when do we require to delete the content of the change log table of standard DSO. I am just fresher to SAP BI.
Thank You

Hi
Deleting data from the change log for an ODS object is recommended if several requests, which are no longer required for the delta update and also are no longer used for an initialization from the change log, have already been loaded into the ODS object. If a delta initialization for the update exists in connected data targets, the requests have to be updated first before the respective data can be deleted in the change log.
Only a temporary, limited history is then retained. The change log can possible become so large you might want to reduce the amount of data volume and delete data for a specific time period.
How to Delete it
Since the change log is also stored as a PSA table, you can use the function for deleting data from the PSA to delete data from the change log.
In the ODS object administration, use the main menu to choose Environment -
> Delete Change Log Data.
Or
Go to the PSA tree.
Use the main menu to choose Settings -
> Display Generated Objects, so that you can display the InfoSource for your ODS object. Your InfoSource has the same name as your ODS object, along with the prefix u20188u2019.
Use the context menu to choose Delete Change Log Data.

Need to get a list of PSA tables and change log tables existing in a PC

Is there a standars table to look up all active DSOs and the change log tables associated to those DSOs?
and also Data sources and the PSA tables associated to that DS.
I need to get a list of PSA tables and change log tables existing in a processchain(whioch deletes the data in them time to time)how do I do this in a quicker way?
Thanks in advance

Hi Ramya

How to update the change log table?

Hi
I am doing some manipulation on the ODS records and writing few new records directly into the active table of my ODS. how do i update the change log table so that i can do a delta from my ODS to further data targets??
i see the fields REQUEST, DATAPAKID, PARTNO and RECORD in the change log table. what values should these fields have for my new records??
Regards
Sujai

Hi,
Please try this option. In stead of writing directly into DSO, do it in another Custom Z DSO. From there, do the FULL load to your previous DSO. This will ensure that the data consistence through the system. Also, do not forget to delete the data from Custom Z DSO once you successfully loaded the data.
Thanks,
Saru

Change Log Table entries without Dates and How to Delete these entries !!

Hello Experts,
I was analyzing Change Log tables of some DSOs and figured out in some tables we don't have Date Column and some tables with date columns but many entries with "00/00/0000" date.
Any ideas on this ? Any idea how records can get into the table without dates and if SAP provides a safe way to remove them (without dates) ?
Many Thanks in advance, Please help.
Regards,
S. Patel

Hi Sunil
Date fileds 00/00/0000 means date are blank..that means either you did not get them from source system or the transformation is not mapped.
Do not delete change log selectively, that might affect your delta loads.
Rather delete old change log ...
From DSO administration ---use the main menu to choose Environment ® Delete Change Log Data.
For more information you can check the log below.
Cheers
Anindya

Change Log table Data

Hi
I have a ODS in which the active records are 608423.
And when i look into the Change log table the records are 1216846 with the status new (N) and 1108438 with status (X) and 1108438 (with status ' ' ).
I did a full load and a delta and this is a Over write ODS. I am little confused with this logic, how it put exactly the double number of records with status (N) in the change log when compared to the active table.
Thx
Thejo.

Hi Thejo,
If you changed a key figure then in the change log you'll see one storno (with minus) record for an old KF value and a new record with a new KF value.
Best regards,
Eugene

Open Hub fetching data from Change log table

Hi Gurus,
I have a scenario where in I have an Open Hub destination whose source is a DSO, and we are sending data into SAP Data services. We found that the data being sent is from the change log table. Is this how an Open Hub with DSO as a source works ? Or is there any possible way we can send data from the Active table of the DSO, when the DTP is run.
Kindly help. Thanks in advance !
Regards
Snehith

Hi,
For Extraction from the DataStore Object, we have the following options for Delta init Extraction:
Active Table (with Archive)
The data is read from the active table and from the archive or from a near-line storage if one exists. You can choose this option even if there is no active data archiving process yet for the DataStore object.
Active Table (Without Archive)
The data is only read from the active table. If there is data in the archive or in a near-line storage at the time of extraction, this data is not extracted.
Change Log
The data is read from the change log of the DataStore object
We can select any of these options for data trasnfer.

Deletion of data from change log table and PSA

Hi,
For a DSO I want to delete data from "Chnage log table" and " PSA Tabel".
For the DSO manage screen I have seen " Environment-> " Delete changelog table" from this we can delete chnage log table data as per my understanding.
at PSA Level Mange screen also I have seen " Environment-> " Delete changelog table" from this option also it deletes the data from change log table or it deletes data from PSA table?.
if this option also deletes data from changelog table then how we can delete data from PSA table?
Please clarify me

Hi,
I am not sure what are you referring to from your point "PSA Level Mange screen also I have seen " Environment-> " Delete changelog table". When ever you click on manage for your psa you will be routed to a popup where you can see all your requests in the PSA table & there after if you click on any single request you will get Environment menu option but there wotn be any change log deletion option available. Please check again? Right clicking on your data source will take you to the manage requests for PSA. You can selectively delete the requests as required.
For DSO when you right click on manage you can directly find Delete change log data option in the Environment tab. there you can select the requests you want to delete.
Also if you want to automate the deletion process then you can simply create a chain and include the steps for PSA deletion & change Log deletion accordingly.
Also it is recommended to keep on clearing the PSA table & Chage log data at regular intervals as it saves the disk space & thus helping in performance optimization
Please refer the below doc at SDN, it will be helpful for you in automating the process of change log deletion & PSA deletion.
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a02ba9e7-bb6f-2c10-09b4-e86b9fcbad41?QuickLink=index&overridelayout=true
Hope it clears your doubts
