Change Tracking many tables

Hi,
I have a number of tables that are all related in some way or another. Lets say there are 20 tables in total here. I need to track changes as they all ultimately will need their changes sending to some other remote database.
Is it ok for me to use just a single change version, obtained at the beginning of my synchronisation code, within a SNAPSHOT transaction for every table I'm concerned about?
I would also need to validate the change version used before getting changes for each table using CHANGE_TRACKING_MIN_VALID_VERSION wouldn't I?
Once I have obtained all the changes for the 20 tables, then I would commit my transaction.
Regards

The thing is, there is a LOT of overhead to tracking many tables.  It is a seductive idea, but you may not realize the full cost in complexity and overhead.
Have you looked at using replication instead?  It's not that much cheaper, but it may at least be easier.
I think you are confusing Change Tracking with Change Data Capture. SDA is talking about the former.
I am not sure that I fully understand SDA's question, but, yes, a single snapshot transaction sounds right. (For Josh: Change Tracking is best used with snapshot isolation.) Particularly, if you want to retrieve changes that are consistent with each
other.
I am a little worrried abotu "single change version", since the version number for each table will be different. (Or at least they can be.)

  • How to get the Reports of Change Tracking Table in MDM?

    Hi!
    Please tell me how to get the reports of Change Tracking Table in MDM which is a System table, directly from MDM without using any interface.
    Thanks in advance for the reply.
    With Best Regards
    Devendra Pandey

    Hi Devendra,
    MDM can track changes on tables and fields. <u>The level of change tracking, and which tables/fields to track, are configurable in the MDM Console</u>. MDM opens a new database on the same database engine as the MDM repository and writes all change records to this database.
    For information of various steps you can visit

  • Track changes on 'Z' tables

    Hi,
    We have a requirement that to track changes on our Z tables. Could any one help me in process of doing this ?
    Thank you,
    Surya

    HI,
      U Read follow this for clarifies u r doubt..........
    As with business objects, we recommend that you activate the logging of changes to table data for those tables that are critical or susceptible to audits. (See the SAP – Audit Guidelines R/3 FI, in Section 4.3.5, for examples of important tables. This document is available at
    http://www.sap.com/germany/aboutSAP/revis/infomaterial.asp. You must also explicitly activate this logging. Note the following: 
    ·        You must start the SAP System with the rec/client profile parameter set. This parameter specifies whether the SAP System logs changes to table data in all clients or only in specific clients. We recommend setting this parameter to log all clients in your productive system.
    ·        In the technical settings (use transaction SE13), set the Log data changes flag for those tables that you want to have logged.
    If both of these conditions are met, the database logs table changes in the table DBTABPRT. (Setting the Log data changes  flag only does not suffice in recording table changes; you must also set the rec/clientparameter.)
    You can view these logs using the transaction SCU3.
    Although we do deliver pre-defined settings, you generally have to modify them to meet your own requirements. Use the report RSTBHIST to obtain a list of those tables that are currently set to be logged. Use transaction SE13 to change the Log data changes flag for these or other tables.
    For more information, also see SAP Notes 1916 and 112388.

  • Track of table changes in a database

    how to keep track of table changes in a database.
    Some records have been deleleted, is there away of seeing that change.

    basically, if you havn't already set up a mechanism to track these sorts of changes, they are already lost.
    there are a number of things you can do. one method that we use is a trigger on the table to insert a record into an audit table for every row that gets changed or deleted.
    oracle has some other built in auditing tools that I'm not familiar with though.

  • No change tracking inside of tables?

    Morning.
    I've written a document in Pages with a table containing cells with text in it. I've sent it to my co-worker. He has made a lot of changes in red-line mode and sent the file back to me. I've opened the document in Pages again. But in change track mode no changes are visible. So I've opened the file in Word 2004 and all changes are visible in change track mode.
    Is there a bug in the change tracking?
    TIA and kind regards, Friedrich

    If it's not designed to track changes in tables then it's not a bug. It's a feature. Or a shortcoming.
    The simple fact is that Pages doesn't track changes IN tables. It will track a deleted table, a moved table or a replaced table +in toto+ but not changes IN the table.

  • Change Tracking Tables

    HI Experts
    I have  a Scenario, where i  need to Track Changes in SAP MDM for field level, as i enable Specific Fields for which i need to track in SAP MDM Console under Admin-> Chage Tracking.
    But as i learnt, Changes will be stored in Database level. can any one help me in knowing the DatabseTables in SQL Server which holds the changes done to a field.
    We are using SAP MDM 7.1, and on Databse is SQL SERVER
    if any one worked on this Scenario, Please let me know the Step to Step Process.
    Thanks in Advance.

    Hi Mandeep,
    Thanks for the Simple blog link.
    i enable change tracking for the Main Table, and i went to SQL and run the select command
    "select [UserName],[EventTime],[TableName],[FieldName],[NewValue],[OldValue]  from [MaterialMaster_Z000].[dbo].[A2i_CM_History]"
    it gives me the result what i expected, with old values and new values. which is all good.
    But the problem is here, where i enable change tracking for a Qualified Table Sales data for the field "Sales unit" which is a Qualifier. and when i change the value of that field in Data Manger,When i run SQL Command  Result is some thing like this
    User Name     Time                          Table      Field          New Value                 Old Value
    Admin     07/07/2010 09:41:32 AM     Products     Update Date     07/07/2010 04:11:31 GMT     01/06/2010 05:14:18 GMT
    So, is that for Qulaified tables we can get only Updated Date and Time not the Value of the Field? is this how system behaves or there any work around to achieve it.
    Can't we achieve the Change Tracking of updated Values of the Qulaified Table data in MDM 5.5 or 7.1.
    Is this case is same, if i deploy Change Tracker Application in MDM 7.1? Qualified Table Fields value Changes can not be Tracked only the updated Time can be Tracked?
    Note: I checked only in MDM 5.5 not yet in MDM 7.1.
    Thanks

  • Tracking the changes in HRP tables for sending thru IDOC

    Hi ALL,
    We are planning to send iDoc to another SAP system with HR Data from different HRP tables. HRP1000,HRP1001,HRP1005,HRP1008,HRP1013,HRP1050 etc
    If we change any PA infotypes they are linked to pernr and we can easily track the changes but if there is any change in HRP tables how do we track the changes and send them thru idoc.
    Thanks
    Bala Duvvuri

    Kiran,
    I am planning to use tocde PFAL  for both inital loads and delta loads of HR data to other system .Can i get all the changes for HRP tables in PFAL without custom programming?
    Let me explain with an example.
    I changed the text for one of the org units and I can see the changes in HRP1000.but how will i send this data to another SAP system using PFAL ,how will i track those changes.
    I heard that we can enable change pointers on each and every field in all the infotypes,so when i change the org unit text and  it is one of the field in PA0001 of every employee a change pointer is triggered .is that true
    Thanks

  • Warning: Full-text change tracking is currently enabled for table or indexed view 'fim.ObjectValueString'

    Hi,
    As per the FIM best practice guide, we are trying to disable full-text indexing on the FIM Service database, during the initial load using:
    ALTER FULLTEXT INDEX ON [fim].[ObjectValueString] SET CHANGE_TRACKING = MANUAL
    ALTER FULLTEXT INDEX ON [fim].[ObjectValueXml] SET CHANGE_TRACKING = MANUAL
    However, we get the following warning:
    Warning: Full-text change tracking is currently enabled for table or indexed view 'fim.ObjectValueString'
    Does anyone know how we can solve this?
    Regards,

    <Going through old threads>
    This doesn't disable change tracking it merely sets it to manual.
    The link below shows and explains the three settings (enabled, manual and disabled):

  • Issue in Change tracker application

    Hi all,
    We have enabled Change tracking in our repository when it was enabled there were only 3 Display fields in our repository and the tracking was done as is in the change tracking application under the column Record shows all the Display fields.
    Now because of business requirements we have activated another field in our repository as a Display field, now when i login to change tracking application old records under Record column still shows the 3 Display fields in the Record column of the change tracker application.
    I went and changed a record which falls in the Change tracking criteria, now i see 4 Display fields in the Record column of change tracker application as there are 4 display fields currently.
    There is an in consistency in the data in the application now for few records there are 3  and 4 fields in the record column. Is this how the system behaves?
    I think the logic is like this when ever there is a change happening in the repository, insert query is used to update the A2I_CM_History table with the existing data(at that moment how many fields were enabled as  DISPLAY )with out any relationship to the Main table Display fields. Please correct me if i am wrong, it was just an assumption.
    If any workarounds to this problem will be of a great help.
    regards
    Sowseel

    Hi Gabor,
    Thanks for your reply!
    We have checked that note and we have indexes existing for few other fields as well in the table, but still we are facing the same issue.

  • Change Tracker in MDM

    Hello All,
          Can you please let me know, how many values get stored in a change tracker.
    For example -- if change tracker is on... for a field Color....
    and I change the value of it from.... Blue  to Red ... then to Green....
    In that case.. will all the 3 value (i.e Blue, Red and Green ) store in the change tracker table at backend????
    Or only the last update value... i.e Red and Green will be stored??
    Can we see all these values in EP.. through standard iViews... or we need to create custom iViews to view these data???
    Request you inputs.
    Thanks,
    Priya.

    Hi Priya,
    Only on saving , the values will get stored in database.
    If you save for all three values , then all three will get saved.
    The old value and new value both entries will be stored in database and can be retrieved by standard change tracker view.

    If you dont have many time use SE11 technical options to activate storing of the logs in table [DBTABLOG|https://www.sdn.sap.com/irj/scn/advancedsearch?query=dbtablog&cat=sdn_all]
    If you have the time, look at [Change Document|https://www.sdn.sap.com/irj/scn/advancedsearch?cat=sdn_all&query=change+document&adv=false&sortby=cm_rnd_rankvalue] and transaction [SCDO|https://www.sdn.sap.com/irj/scn/advancedsearch?cat=sdn_all&query=scdo&adv=false&sortby=cm_rnd_rankvalue] where [Change-Document Object |https://help.sap.com/saphelp_nwmobile71/helpdata/en/2a/fa018f493111d182b70000e829fbfe/frameset.htm] are maitained
