Use of change log

Dear Experts,
Could you give some clues as to how change log is used .
When do you pull data directly from it and what mechanism is used for pulling data from change log.
Thanks,
Suzie

How to use the change log in ODS to track Delta change?

People say that historical data (like Delta change) in ODS can be tracked in the Change Log. How to use the change log to track historic data?
Thanks

Kevin
See if it helps
Every ODS object is represented on the database by three transparent tables:
Active data: A table containing the active data (A table)
Activation queue: For saving ODS data records that are to be updated but that have not yet been activated. The data is deleted after the records have been activated.
<b>Change log: Contains the change history for delta updating from the ODS Object into other data targets, such as ODS Objects or InfoCubes for example.</b>
An exception is the transactional ODS object, which is only made up of the active data table.
The tables containing active data are constructed according to the ODS object definition, meaning that key fields and data fields are specified when the ODS object is defined. Activation queue and change log are the same in the tables structure. They have the request ID, package ID and the record number as a key.
Data base structure changes

Tracking Order Changes - Use of Change Log

Folks,
One of requirements I have is to track changes done to a sales order. The user wants to know anything (every field) that has been changed on an order compared to the previous sales order record. I think I can use the change log to do this but not sure if it tracks changes of all fields. Following are the questions I need to confirm
Can the change log used to meet this requirement?
Does the change log track the changes to every field on a sales order including the user defined custom fields?
Please let me know.
Thanks,

UDO Change log error

Hi,
I created a UDO in B1 2007 and enabled the option to log changes i.e. Change log functionality. I created a custom form as the UI for the UDO. The following functionality works without issues:
1. Able to add/update data via the custom screen into the UDO tables
2. Every time i make a change a new instance of the record is avaialble in the AXXXX tables i.e. the log tables.
3. When I click on Tools --> Change Log i see a line there for each instance in the AXXXX table.
My issue is:
When I select 2 instances on this window and click "Show Differences" button, I get a red message on the status bar saying "Internal error (1) occurred [Message 131-183]".
My questions are:
1. My understanding is B1 will show the differences like it does on any other document form i.e. Sales order, quote etc. Do we need to do any custom programming?
2. In stnadard sales order, you have the ability to double click on each instance to see the details of that record. Is it possible with a UDO or does that have to be custom programming?
Thanks,
Gopal

Hello Viswanathan,
I am trying to use the change log on my UDO & custom form as you are doing, but I have not had as much success as you have had. Regarding your list of 3 items, numbers 1 and 2 also work fine for me, but number 3 (selecting "Change Log" from the tools menu) is impossible because the change log option is disabled. I have tried enabling it when my form is displayed, but that does not work.
I was wondering if you could offer me any advice on what you did to get step 3 working? I have posted a question regarding this on the forum. If you care to respond to it, then I can give you points for the answer:
[Can change log be used with UDO master table/lines?;

HOW TO USE FUNCTION Deletion of Requests from the Change Log IN PRCSES CHAN

Respected all
i used Deletion of Requests from PSA from the prcess chain and found good results, now i have only one request at the psa and thus i am doing good space utililisation. but when i am using Deletion of Requests from the Change Log i am not getting any changes in the request of dso. kindly let me know how to use this 2nd function.
thanks
abhay

Hi Mahodaya,
As per SAp standards its good to delete the requestes that are no longer needed for the delta update and no longer used ffor inti from the change log table and the data is loaded already in to DSO.
Goto RSPC
Click on create New PC -> enter the PC name n long descp
Next we need to define the start process for the PC.Maintain the start variant process.save n come back.
for deletion of change log we have option in the Other BW Processes -> deletion of requestes from change log
Once u select the option we get a dialoge box here we need to create the variant for the process enter the process variant n long descp. cick ok.
Next in the maintenance screen for the deleting the request from change log table will appear.
Enter the selection patterns to which the requestes should be deleted from the change log.
In the maintenance screen, select one or more Data Store objects for which requests are to be deleted from the relevant change log tables under Data Store Object column and select theInfo Area of the corresponding Data Store Objects under Info Area
If you select the first check box exclude selction pattern, this means that del of requests from change log table will be ignored.
or
We can delete the requests which are Older than N-number of days (or) date in the above screen. For this one, enter the number of days (or) date in the filed Older than .
OR
If we want to select the requests with a certain status then we can also do in the above screen. We can select the following status indicators from the above screen.
Delete Successfully Updated Requests Only -This status will delete only requests which
are successfully updated into corresponding Data Store objects.
Delete Incorrect Requests that were not Updated - This status will delete only incorrect requests which are not successfully updated into the corresponding Data Store Objects.
Delete Activation Requests only, No Load requests- This status will delete only the activation requests (requests that begin with ODSR_... ). No load requests are deleted.

Any BAPI or FM to use to update the Customer Address with change log?

Hi, does anyone have used any BAPI or FM that will update the customer address (Central Address management fields) and the change will be logged in the change history of customer master? I have tried several FM that can update the fields but none of the change will show up in the change history of the customer master.
So far, I have tried the following FM:
ADDR_MAINTAIN_COMPLETE
ADDR_UPDATE
BDC is not acceptable due to high volume of data. However, the change log is also required.
Please share any advice.
Thank you,

Hi Minami,
for chenge address use FM : BAPI_BUPA_ADDRESS_CHANGE       (SAP BP, BAPI: Change Address)
otherwise check with below FM ,for address related information
BAPI_BUPA_ADDRESSES_GET              SAP BP, BAPI: Determine All Addresses
BAPI_BUPA_ADDRESS_ADD                   SAP BP, BAPI: Add Address
BAPI_BUPA_ADDRESS_CHANGE                 SAP BP, BAPI: Change Address
BAPI_BUPA_ADDRESS_GETDETAIL             SAP BP, BAPI: Read Address
BAPI_BUPA_ADDRESS_GET_NUMBERS    SAP BP, BAPI: Read Address Numbers
BAPI_BUPA_ADDRESS_REMOVE                    SAP BP, BAPI: Delete Address

No change log is created when updating the customer master using LSMW

Hi Gurus,
I am a bit confused on why no change log is created when I use the LSMW to update the customer master. What I update is the customer partner of the customers. For example I have a sold-to 1000 then a customer representative (Z3) 50001, now when I use the LSMW to change the customer representative to 50002 it is correctly updated however no change log is found if you check for the changes on that specific customer. This is a bother for me since I want to send all the customer changes through IDOC and the processing needs to access the change log.
Thank you.

Hello,
What process are you using object, BAPI, etc.

Change Logs for TCODE -- FILE

Hi Friends,
    Please help me in finding the change logs for the TCODE FILE,
    i.e The changes made to the Logical paths
   I had tried Utilities---->change logs , but unfortunately i cannot find any changes logs
   But there are changes made to the logical paths in my system but i cannot see them in change logs
thanks
chandrasekhar j

rec/client is a profile parameter, you can view the settings in transaction RZ10. However I find program RSPARAM more useful, the report lists all system parameters with their default and altered value. Also if you double-click on a parameter you can get to the full help text for its meaning.
The parameter essentially switches on table change logging for configuration tables (based on the technical settings of the table) and has to be set before the changes are made.
Hope this helps.

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.

Sales Orders Change Log question

Hi All,
I am currently working on a project that involves querying SAP Database to get custom reports via web browser, I've made a lot of advances and most of the site is ready but I'm missing just one item that I hope you could help me.
Thing is I am working with the Sales Order change log and the problem comes one a user deletes a row. If I go to the change log inside SAP and see the differences a new record will be shown saying that row X was deleted and
if I go to the database (ADOC and ADO1 tables) I don't have a way to see wich row was deleted.
My way of doing this is to check for the number of rows on the current state of the sales order and check the same on the previous instance of the SO and see if a line was deleted. Then I would have to check row by row between instances what rows are there and what row is missing and store that info. I think this kind of approach will definitively kill the server.
I was wondering if some one can give me a hint about how to approach this problem. Does any body know how SAP works on this area?
I'm working with SAP2005A and SQL Server 2005 Standard Edition.
Any help is greatly appreciated.
Thanks!
Alejandro.-

Hola Alejandro,
Thanks for your answer, as I see it I'm doing exactly what you proposed but the problem comes with the following scenarios:
a.- If I post a new SO with two lines I will have on the ADO1 table two records with the values 0 and 1 for each line respectively but if I delete the item on LineNum = 1 and then I add a new item, this last item will be also created with LineNum value = 1. This is not a complicated thing to do but the problem comes when the user is used to work with SOs with several items at detail level and is used to add and erase lines once in a while and as I see it it's very difficult for me to track those specific changes. There's also the fact that on the Log table a new instance is created every time the user hits the update button regardless if a modification was actually made or not. I mean I would know that a line was deleted or added but I would have to start comparing each field on each line of a sales order with it's previous instance to check what was actually added/deleted and I'm afraid that this may affect the server performance. I know that SAP does this without affecting to much the system resources and that is what I'm trying to find.
I forgot the other scenario I was considering he he I will post again as soon as I remember it but I hope I'm explaining this ok (I'm not very good at explaining...) If not let me know and I'll try to explain again.
I'm also working on trying to get another approach to see what comes up...
Thanks for checking this thread, your answers are helpful.
Regards.

TS3988 iCloud will not accept any passwords after upgrading OS. 2 days of trying every password I have ever used, AND changing Apple ID and iTunes ID, still nothing. Can't backup on iCloud anymore.

How can I use iCloud again after upgrading OS to Mountain Lion? 2 days of trying every password I have ever used, AND changing Apple ID and iTunes ID, still nothing. Can't backup on iCloud anymore.

Apple ID's can be used for anything, a single ID can be used for all your accounts (ie iCloud, iTunes, MAS, Apple community etc), ideally this would be the way forward. So far as iTunes goes you need to continue to use the same ID as you have always used or you will lose access to your previous purchases and your iTunes match subscription.
If you are using a second ID for iCloud, you can continue to do so or use the ID you use for iTunes, but if you choose the later you will need to move all your calendar, contact etc data to the account using the ID you use for iTunes.
When (if) you change which account you use you would delete the account on an iOS device and log back in with the correct details, on a mac you would sign out in the iCloud system preference pane.

Change log issues-2 images for a single requests

Hi ,
in change log table for a single request i found 2 before images and two after images, is this normal behaviour if not when can we see the such type of scenarios.
because it leads to zero records when it isn updated in to the further data targets.
thanks.

the listener is NOT involved with any existing session.
stopping & restarting the listener has NO impact on existing sessions.
I suggest it is better to control network access to any system using a Firewall which is the best tool for this task.
Yes, it is possible to have more than 1 listener. It is also possible to poke yourself in the eye with a sharp pencil.
I suggest that you should avoid both of these possible activities.
Simply put having multiple listeners is wrong for multiple reasons & should be avoided.
