Logic for data transfer

Hello,
I have a requirement, wherin there are 10 tables for which the data changed/inserted/deleted for any field needs to be transferred to third party.
I have gone through the change pointer concept and found that SAP does not recommend this as this will create large number of change pointers in the system
Second option was to create techincal log for each table to log the change.But here again it will slow down the system as everytime system has to write the log when updating the table.
Third option was to write report to get all the record for a particular date based on change date from the table and write down into custom table. The custom table is then treated as source. But here the problem comes when there is no 'Change date' field in the table. For some table we do not have change date field.
Can somebody suggest what should be the best approach to filter the changed data.
Thank you!
Arvind

Hello Arvind,
                   why not u try to achieve IDOC's concept as whatever the change will occur in Database that will store in idoc.And most beneficial thing is this that u can see idoc whenever u want and can easily find out what changes has done by which idoc.So i suggest u to try IDOCs.
Thanx,

  • Need to build communication redundancy using serial RS-232 for Data Transfer b/w Host and RT irrespective of TCP/IP Data Transfer

    Hi - I would like to build the logic in which it should accomodate the communication redundancy using serial RS-232 for Data Transfer b/w Host and RT irrespective of TCP/IP Data Transfer.
    I want to do data transfer b/w host and RT through RS232 VISA portal whenever TCP/IP ethernet cable has been unplugged from the controller continuosly , it should keep on checking for TCP/IP link re-establishing also , when ever the tcp/ip link established again that time the communication should be using in that link only. This is accomplished by deploying the RT vi as execuatbale file. I made some logic regards to the above said logic , bur it was not working as much I expected.
    I request you to go through the attached two VI's and let me know , what I did wrong in that,
    Please do the needful.

  • HT5287 If DVD Movies, Audio CD's and even burning CD and DVD's are not supported, what is the point of DVD & CD Sharing then? Wouldn't it just be better to remote in or use a thumb drive if it's only able to be used for data transfer?

    If DVD Movies, Audio CD's and even burning CD and DVD's are not supported, what is the point of DVD & CD Sharing then? Wouldn't it just be better to remote in or use a thumb drive if it's only able to be used for data transfer?
    Or am I missing the bigger picture?

    As long as you have a Superdrive or an external burner/drive, burning, watching, installing, etc. from CD or DVD will work just fine. And so will sharing.

    The bug is known, and a patch has been submitted: https://bugs.freedesktop.org/show_bug.cgi?id=80151. There's been no update since friday, so I wonder what the current status is, or if it's up for review at all.
    Does anyone know how we can be notified when this patch hits the kernel?

  • JPA - Best Practice For Data Transfer?

    I've been considering an alternative method for data transfer between applications, by using Serialized or Encoded to File JPA Entities. (either Binary or XML)
    I know this procedure may have several draw backs as compared to traditional exported SQL queries or data manipulation statements, however, I want to know if anyone has considered or used this process for data transfer?
    The process would be to
    - query the database and load the JPA Entities
    - Serialize or Encode them to file
    - zip up the entire folder with the JPA entities
    - transfer the data to destination machine
    - extract the data to a temp directory
    - reload the JPA entities by de-serializing and persisting them to the database
    The reason I'm considering this process, is basically because I have a desktop application (manages member records, names, dates, contributions, etc) used by different organisations in different locations (which are not related except by purpose ie clubs or churches) and would like to have a simple way of transporting all data associated with a single profile (information about a member of the organisation) from one location to another in a simple way, ie users interact only with the application without the need for any database management tool or such.
    I'm also considering this because it is not easy to generate an SQL Script file without using a dedicated Database Management Tool, which I do not want the application users to have to learn how to use.
    I would appreciate ANY suggestions and probable alternative solutions for this problem. FYI: I'm using a Java DB database.

    In summary you are moving data from one database to another. True
    You only discussed flow one way. Well the process is meant to be bi-directional. Basically what I envision would to have something like:
    - the user goes to File -> Export Profile...
    - then selects one or more profiles to export
    - the export process completes and the zip archive is created and transfered (copied, mailed, etc) to the destination location
    then on the destination pc
    - the user goes to File -> Import Profile
    - selects the profile package
    - the app extracts, processes and imports the data (JPA serialized for example)
    Flow both ways is significantly more complicated in general.Well if well done it shouldn't be
    And what does this have to do with users creating anything?Well as shown above the user would be generating the Zip Archive (assuming that is the final format)
    Does this make the problem clearer?

  • Is there any support for data transfer compression in oracle XE?

    Thank you for reading my post.
    I am wondering whether it is possible to ask database and JDBC driver to use some sort of compression for data transfer?
    I want to reduce the network workload as much as possible.

    AFAIK, Not directly from Oracle.

  • E-Rec: XI for data transfer

    Hello Experts,
    I am working on an implementation project where SAP E-Rec is on different box. We are on EhP5. We have XI for data transfer between both the systems (ECC and E-Rec). Now, when we use RFC to connect these systems, we use PA48 in ECC to hire candidates as employees which in turn pulls data from T752F table. Now as we are using XI, how/where does data flow?
    Also, please guide in case candidate is a rehire, how and where to capture his previous perr number to validate candidate is actually an old employee? Instead of T752F, which table is populated which creates an entry in HR admin's UWL. Please help understand.
    Thanks and regards,
    E-Rec Beginner!

  • Establish a connection through RF modem's on client & server side & to set up PPP communication for data transfer

    hi
    can any1 over here help me out in how to establish connection between 2 RF modem's for data transfer , between client & server USing LABVIEW?
    I want to establish a connection between 2 PC's through  RF modem on client & server side & to set up PPP communication for data transfer.
    (I have tried data transfer through RS-232 using TCP/IP whn the 2 PC's are connected over ethernet... which is working.
    I also tried connecting loopback cable between 2 PC's COM port & geting data transfer using VIsa configure serial port & other visa functions  ... which is working)
    can u guide me how to establish connection between 2 RF modem's using LABview?
    & how does the data transfer take place between 2 RF modems through RS-232?
    is it using TCP/IP?
    If you got any links to go abt this issue do send me related links .. or any examples .....
    I am currently using Labview version 8.
    Waiting in anticipation.. reply ASAP..
    thanking you
    Regards
    Yogan..

    Howdy yogan,
    Maybe you could clarify a few things for me, and we'll see how we can help ya. TCP/IP protocol occurs through an ethernet connection; RS-232 communication occurs through an RS-232 serial connection, typically through a cable that has a DB9 connector on both ends. Do you mean that the RF modems in question have the option to communicate via RS-232 and/or via TCP/IP ethernet? Specific information like the manufacturer of your RF modems, the model number of your RF modems, and how you connect the modems to the PC would enable us to give you more efficient support.
    You can check our Instrument Driver Network (IDNet) to see if a plug-and-play/IVI driver already exists for your RF modem. (You'll need to know its manufacturer and model number.) In the case that you do find an IDNet driver for your modem, you can use this KnowledgeBase article for instructions on how to use the driver.
    Another excellent resource to consider is the NI Example Finder. You can access this within LabVIEW by navigating to Help»Find Examples and then searching for serial or TCP/IP examples.

  • Control parameters for data transfer

    Hi!
    There are no data in SBIW source system - General Settings - Maintain Control Parameters for Data Transfer.
    How does it have an influence on loading data?

    Hi,
    Maximum size of a data packet in kilo bytes
    The individual records are sent in packages of varying sizes in the data transfer to the Business Information Warehouse. Using these parameters you determine the maximum size of such a package and therefore how much of the main memory may be used for the creation of the data package. SAP recommends a data package size between 10 and 50 MB.
    Frequency with which status Idocs are sent
    With this frequency you establish how many data IDocs should be sent in an Info IDoc.
    Standard settings
    Frequency 1 means, for example, that there is an Info IDoc for every data IDoc. In general, you should choose a frequency between 5 and 10 but not greater than 20.
    Recommendation
    The larger the packet size for a data IDoc, the smaller you should set the frequency. By doing this, you make it possible to get information on the respective data load status in relatively short time periods when uploading data.
    Maximum number of parallel processes for data transfer
    Select a number greater than 0.
    Parallel processes can be set from the SAP core release 3.1I onwards.
    These parameters are, therefore, ignored in releases before 3.1I.
    However, there is a possibility of importing the SAP release 3.1I into earlier releases.
    The more parallel processes that can run the better the performance of your system will be. However, you must bear in mind the number of available dialog processes here.
    It will be fine and more effective if you use sap recomended values in those respective fields

  • Using Nokia 1200 CA45 connection for data transfer

  • Is it mandatory to use Business object for data transfer and work flow?

    <font size="3">
    <pre>
    In our enterprise projects we deal with some screens where we add or update some data and again
    we retrieve that data and display to user in various ways like displaying on screen as
    a report or viewing in excel etc.. Most of the times, though we identify the business objects
    based on the nouns in requirements document, really while implementing there will not be any
    business logic in the objects. Almost all the objects which we identfy as business objects
    may have methods like add, delete, update and retrieve methods. Still in these cases, is it required to
    have business objects or can we use transfer object to send the data for saving and retriving or any other
    pattern/guideline is there for dealing such cases?
    I really appreciate your comments on this topic.
    Also I apologize ahead of time if my explanation is not clear to you.

    In my opinion, DAO pattern would be suitable for you. Generally the DAO (Data Access Object) will have the CRUD (create, read, update, delete) methods to retrieve data from data-source (e.g. database). Based on the data it will create the DTOs (Data Transfer Objects) and pass them to the caller. It will also receive the DTOs from the caller and save it the data-source. Thus in your case you can
    - remove the CRUD methods from the Business Objects (BO) and make them pure DTOs and use them with DAOs (If you are using JDBC codes inside your application and you don't have much of validation or processing logic in your BOs).
    http://www.corej2eepatterns.com/Patterns2ndEd/DataAccessObject.htm
    OR
    - use BOs in combination in DAOs (if using the database connection from a pool and BOs are having complicated processing logic).
