Change log data

Hi,
We have lots of data loaded in DSOs. We are in a process of clearing the change logs. And want to find out from which date the data is available in change logs.
What is the best and quick way to check the date from which the data is available in change logs.
Thanks in advance.

Hi,
I have been doing this way only to check the from date. Its like a trial and error method. I input fiscal year period eg: 001.2008 to 012.2008 and check the number of entries. This way i will have aidea if data is available for thie period. Else check for other dates.
But this has become very manual and cumbersome process. Is there any other way to find from when the data is available.
I hope you get my point.

Have you tested this process type changlog deletion before moving to prod per your data flow?

Change Log data into SAP BI

Any best practices for getting change-log data similar to that captured in CDHDR/CDPOS tables into SAP BI? What options exist for tracking changes to sales orders or invoices into SAP BI without touching CDHDR/CDPOS tables?
Thanks,
Vinny Ahuja

hi,
you check weather that data source carried out delta loading or not by using
RSA7 T-Code. In represents to sales or invoices, if that particular data source meant
for delta loading into bw means it will show status green. by seeing this particular
data source carried out delta loading in to bw system.
if helpful provide points

Delete change log data

I was going through posts regarding delete change-log data but I am bit confused with the answers.My data is moving from ODS to CUBE and for the performance reasons I want to delete Change-log data from PSA and keep only 3 day requests.My question - if I delete Change-log whether it effects the delta data from ODS to CUBE.Change-log maintains images so If I keep only 3 requests there will be images of only those 3 request data.If this happens then it will effect all the delta data going into CUBE
Let me know your suggessions
Rgs,

Hi,
     Yes, you can delete the data from the Change Log unless until you do not need to re-construct the data again from the change log table.
     As a good principle for safety reasons if data is not too large, you can keep the data for 7days. This will ensure us to be safe. If something went wrong on week-end say 2 days were gone and on 3rd day the user has identified and raised a ticket on this. Forth day will be for analyzing and re-construction.
    So, unless until if the data is not too large, you can keep it for 7 days in the Change log table and the rest you can delete. As said by the other members, deletion of Change Log table does not affect the delta as it compares with the Active Table and creates a Before Image and After Images records and updates in the Change Log Table.

Extracting HR Change Log Data to BW

Hi Guru's,
does anybody know how to extract data from the HR change log (among others, cluster table PCL4)? I found two function modules HR_INFOTYPE_LOG_GET_LIST and HR_INFOTYPE_LOG_GET_DETAIL
that should be giving the data in the correct format.
Has anybody ever used these Function modules for (delta) extraction to BW?
Or are there other ways to extract this type of data?
I already got some pointers from CSM Reddy in a previous posting:
http://help.sap.com/bp_biv170/html/Bw.htm
http://help.sap.com/bp_biv235/BI_EN/html/bw.htm
But they don't seem to work any more.
Best regards,
Arno

Those links you gave didn't work for me . . .
I have toyed with using those function modules in the past. I was trying to solve an issue I had: With heavy customization on 0EMPLOYEE, it took forever to extract the data for that infoobject as we had more than 10 extractors . . .
I no longer have access to the BI system, but I used one of the function modules you mentioned and loaded it into a DSO. From there, I used the DSO as a filter for my 0EMPLOYEE extractors. Using some ABAP, I passed to the extractors a list of employees who had data change in the previous day and extracted all of their information (should extract all in that case to properly get the begda and endda for the master data).
It had the potential to really speed things up but I never got to finish so I've never seen it in a production environment. Hopefully this helps . . .

Issue with Incremental migration - Change log data gone

Project Info :
We are migrating clients MOSS 2007 environment to SharePoint 2013 using Avepoint Docave migrator. It’s a migration and new development project where in client require new components and UI to be developed
Problem statement :
We had done last incremental migration of the data in August 2014 and when we tried doing the incremental migration in December it was found that “Change Logs”, based on which Docave does the incremental migration have been wiped out due to the Change log
duration set to 60 days by the client.
Docave support is saying that the only way to get the correct data is to perform full migration. As we have done lot of page fixes post migration, we want to avoid full migration.
Just for the information, Change logs refer to the "Event cache" table created for each content Database and the duration of the change can be set via
Central Administration > Application Management > select Web application > General Settings >Resource Throttling > Change Log
Any thoughts/approach on how shall we proceed to tackle this situation
Regards,
AMit

Hi,
As Avepoint Docave migrator is a third party product, I suggest you can contact the corresponding support for help.

Change log data is NOT captured for PO screen exit fields

Hi,
We created a new tab at item level for PO Screen(ME21N) for the purpose of STOs(Document Type UB) & created 3 New fields in that new tab through Screen Exit( SAPMM06E, SAPLXM06 0111 ).
When we are entering data in those 3 new fields while creating new STOs, those data are captured in EKPO table.
When we are changing the OLD STOs for those 3 new fileds, data is modifying in EKPO table. But changes are NOT inserted in CDHDR and CDPOS table for those 3 new fields.
<b>Please help us to track the changes in those 3 new field data changes for old STOs.</b>
Please let me know if you need any further clarification regarding this.

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.

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.

Duplicate records in ODS change log

Hi Experts,
I have loaded records from R/3 to ODS (psa and then data target).
Records looks good in ODS active data.
Then I did a delta load from ODS to InfoCube and I have recevied are the changed entries to Cube.
Then, I checked the ODS and the Datamart status was Checked.
But, when I did a delta load again after couple of days from ODS to InfoCube, I received some duplicate records. I have checked the Change Log of ODS and the duplicate records were there.
I am not sure why my ODS is transporting entries from the ODS request for which there was a datamart status already checked.
( I cannot do selective deletion because there are about 1000 duplicate entries and in random order..).
I beleive my best bet would be to:
1. Delete both the delta load requests (the request with correct records and the request with duplicate records) from InfoCube.
2. Remove datamart status from ODS
3. Delta load from ODS to InfoCube
Please let me know if this will solve the issue or I will still get the duplicate records in InfoCube?
Also, do I need to Delete Change log data?

Hi Ramesh,
The entries in Active Data of ODS looks good. No duplicates.
When i checked Change log,
I had entries in ODS change log from two differnent requests.
Request1 (Full repair request via PSA) in ODS (ODSR_xxxx1) has records the same as in R/3
(eg., entry for DocumentA has keyfigure as value +$1000)
Request2 (Delta Load via PSA) in ODS (ODSR_xxxx2) has two records with posive and negative keyfigues
(eg, entries for DocumentA has keyfugure as value +$1000 and DocumentA has keyfugure as value -$1000)
So, not sure if I should call these records as 'duplicates'.
But, I see 3 entries in InfoCube for DocumentA with keyfigure values as +$1000, -$1000 and +$1000.
I beleive the ODS change log should actually cancel the earlier +$1000 and load the new +$1000 entry.
But, it seems to be not replacing the old one.
I hope i am clear.

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.

After deletion ODS change log, Delta upload OK?

Hi all,
Now I am reducing data from BW server. For this purpose, I will delete ODS change log. Both of data "from ODS" and "to ODS" are uploaded by Delta Upload.
If I delete change log after last delta initialization, is there any problem to next delta upload?
For example, the last delta initializing was done April 1. And I delete the change log up to April 30. After this operation, can be expected any problem to Delta upload?
Bamboo Shampoo

I dont think it will cause any issue with next delta loads.
Data goes from ODS to its targets from change log table.
But I think better have strategy like..'delete change log data only for requests older than say...1 month or 2 months..'
so that if u have problems with recent data loads..u can reload easily..
u can also try cleaning up old requests from the PSA tables in the system..
cheers,
Vishvesh

Change Log/Delete PSA

Hi Gurus, I am on 3.5. When I go to RSA1, then to PSA. Select a a request, right click and select "Delete PSA Data". Why does it say "PSA / Change Log". Does it mean, I am deleting Change Log data too?

Bigtoja,
That may happen in case of ODS. For ODS change log data and PSA (for subsequent target from this ODS) are stored in the same table (change-log of the ODS table) . Those data are identified in the same table as "ODSR" for change log entries and "REQU" for PSA entries.
Hope this helps!

ODS Activation Returns 0 records in the Change Log

Hi All,
I have question regarding the Change Log build after the ODS req has been activated.
BW system - SAP NetWeaver BI 7.0 - Level 15
Upon loading a delta request into the ODS and Activating, it adds no records to the change log table.But the active table gets correct records
Checks I Did
ODS -> Menu-> Environment -> Delete Change Log Data.
     No job scheduled or runing to delete the change log reqs (sm37)
RSRV - Check the Status of the Generated Program of a Data Store Object
ODS - reactivation to see if it works..
ODS Manage - Auto Req Processing set Quality status, Activate DSO to Yes.
The Activation Log shows at the end that they were no changed records added:
Data pkgs 000001; Added records 0; Changed records 0; Deleted records 0
Log for activation request ODSR_4APQQHKM459YNO7CIGCE0629U data package 000001...000001
Activation of records from DataStore object C_PUR_C sucessfully finished
U table for DataStore object C_PUR_C deleted successfully
Job finished
Can anyone help on the above issue??
Thanks
Rao

Hello Siggi,
Referring to the previous post:
I have a situation where few documents are not transferred to Change log during DSO Activation, though the After image values of these records are reflected in Active table.
I have found one common pattern for those documents which are not recorded in Change Log.
They have two pairs of After and Before image records.
First Pair like this: Eg: Overall status as the only data field.
Sales Doc     Overall Statuls   Recordmode
1001             C                      X
1001             A
Second pair:
1001            A                      X
1001            C
If we consolidate all these 4 records there seems to be no change for any data fields. Should I consider this as the standard behaviour while activating DSO - causing these records not to get recorded in change log?
Or is there any SAP Note that can make sure the change log gets populated in such case.
Hope my details are clear to you..
