Regarding Transformation and Data Transfer Process(DTP)

Dear Gurus
1) Transformation replaces the transfer rule and update rule.
2) DTP replaces the info package.
Hencse, there is a some advantages are there in Transformation and DTP.
I couldn't understand in help.sap.com.
Could you please tell me in simple language what all are the new features are there in Transformation and DTP which is not possible in Transfer rule, Update rule and infopackage.
Thanks and Regards
Raja

Hi Raja,
These are the advantages of DTP and Transformation over their predecessors.
DTP:1)Improved transparency of staging processes across data warehouselayers (PSA, DWH layer, ODS layer, Architected Data Marts)
2)Improved performance:Intrinsic parallelism
3)Separation of delta mechanism for different data targets: delta capability is controlled by the DTP
4)Enhanced filtering in data flow
5)Repair modes based on temporary buffers (buffers keep complete set of data)
Transformation:   SAP NetWeaver2004s significantly improves transformation capabilities. The improved graphical UI contributes to decrease TCO.
1)Transformation Improved performance, flexibility and usability 
2)Graphical UI
3)Unification and simplification of transfer and update rules
4)New rule type: end routine
5)New rule type: expert routine (pure coding of transformation)
6)Unit Conversion Capabilities for unit conversion during data load (and reporting)
Assign points if it is helpful.
Cheers,
Bharath

    Hi guys,
    Please some bosy help me out by providing the differences between Transformation and Data Transfer Process.
    thanks in adwance

    Hi Omkar,
       Trnasformations providing the mapping between Sorce fields( datasource to  data target).  only map the structures..
    <b>Transformations:</b>----
    -->Trsnsformations are used to create mappings between two BI Objects and to
    transform data from BI Source(From where) to BI Target .
    -->You can create One-One Mappings between source and target in BI
    -->In transformations Source is : DataSource, InfoSource, DataStore object,
    InfoCube, InfoObject and InfoSet
    -->Target is: InfoSource, InfoObject, DataStore object and InfoCube.
    -->Transformations replaces the transfer and update rules.It's like creating transfer
    rules and update rules.Through these rules/mappings/transformations, the
    system is going to transform data from Source to Target.
      but DTP  means.. the data loading procedure will be  done with this step..
    <b>DTP :</b>
       DTP is used to transfer data from PSA to the infoprovider.
    The data transfer process can also be used to control data distribution from a BI system into any target outside of the BI system. For this purpose, a data transfer process with an open hub destination is used as the target.
           Since Deltas are now based on request from PSA ,you can have multiple datatargets pulling data with same selection criteria from same datasource(ECC) with INITS/DELTA,not possible earlier.

  • Data Transfer Process (DTP) - Messages Never Received and Times Out

    Hello,
    I'm having an Issue with DTPs at the moment. First I'll give you a little background on the system
    Formerly BW 3.1, upgraded recently to BI 7.0 (Support Pack 15). Most of our Data Flows are still under 3.x style, but many are being migrated or recreated under BI 7.0 standards.
    I am able to successfully load data using DTPs however on many, and seemingly random, occasions the message for individual data packages under "Processing -> Updating InfoProvider" never arrive, and thus the DTP never completes and eventually times out.
    Under BW 3.x it was a simple matter of changing the QM status to Red and then "Update Manually" on the data package that did not receive the message. This would reprocess and complete the data package, allowing you to then turn the QM status Green and move on.
    Under BI 7.0 I do not seem to have any options for the Data Packages regardless of QM status. I have not found a way to resolve this situation and in every instance had to delete the request from the InfoProvider and try again. It seems like a rather large design flaw, so I'm hoping I'm missing something.
    Any suggestions would be greatly appreciated.
    Thanks,
    Matt

    Three things to be noted:
    1. Dont use the std. settings of 50000 records. Change it to 10000 records in DTP.
    2. Since you are not getting till Updating tab, I foresee something wrong with routine..start/end/transformation. Check there how much time it is taking.
    3. I dont think we have any option as you mentioned for QM. We need to delete the req and start the DTP again.
    Thanks..

    Hi
    It looks like a Memory issue. Try restarting the load when the system is relatively free.

  • How can I delete a Data Transfer Process DTP ?

    I'm trying to delete a backup cube I don't need any more. I get message "InfoProvider xxx is being used externally". It tells me its being used by DTP_4JI7IPQWI6F7IY1O3H0D6RGYM. I can't find this DTP in Modeling, but it does exist when I look in the Metadata Repository. I can see it in table RSBKDTPSTAT where field OBJSTAT = INA and field ACTIVFL = X - which I think indicates there is a problem.  It also exists on table RSBKDTPTH.  Can anybody tell me how to delete it so that I can delete the cube eg is there a program that can do it? Thanks, Brigitte

    The DTP in question may have been hidden from viewing due to some failed transport.
    You might have to locate that DTP in your dev system and transport it to production again and then delete in dev system and transport the deletion to production again.

  • DTP (Data Transfer Process)

    Hi, I would like to know more about DTP (Data Transfer Process), how can i use it to replace infosources, transfer rules and update rules in just one transformation.
    I will be very grateful for your comments and your help...
    Thanks and regards!

    hi,
    You use the data transfer process (DTP) to transfer data within BI from a persistent object to another object in accordance with certain transformations and filters
    It is like a replacement of the info packages in the olderr versions.
    Data transfer processes are used for standard data transfer, for real-time data acquisition, and for accessing data directly.
    youu can refer to this link for mor infos.

  • Data Transfer Process and Delete Overlapping Requests

    Hi All,
    We are on BW 7.0 (Netweaver 2004s).  We are using the new data transfer processing and transformation.  We want to use the ability to delete overlapping requests from a cube in a process chain.  So lets say we have a full load from an R/3 system with fiscal year 2007 in the selection using an infopackage.  It gets loaded to the PSA.  From there we execute the data transfer process and load it to the cube.  We then execute the delete overlapping requests functionality.  My question is, will the DTP know that the infopackage selection was 2007 so it will only delete requests with selections of 2007 and not 2006 from the cube?  Basically, is the DTP aware of the selections that were made in the infopackage?
    Thanks,
    Scott

    Hi Everyone,
    Figure it out...on a data transfer process you can filter the selection criteria - go to the extraction tab of a DTP and click on the filter icon.  Enter your seleciton conditions to pull from the PSA....these seleciton conditions will be used to delete the overlapping requests from the cube.
    Thanks

  • Data transfer processes and info packages in new client

    Hi,
    We have created new client from the development client.
    The Info cubes and update rules are available in new client, bu the data transfer processes and info packages are not moved to the new client.
    What is the actual sequence of steps to be followed when new client created from development client. Have I missed some sequence or steps. What are the sequence of steps to be followed when created a new client.
    Kindly suggest to resolve this issue.
    thanks and regards
    Murugesan

    Hi,
    I have never seen clients created on the BI system. As such all the objects in the BI system are client independent as well as the data stored in the tables does not have the mandt field. Hence you cannot distinguish different clients in the BI system. Also if you notice all the request in BI are workbench request and not customizing requests.
    I do not think this is a viable solution. Maybe you can contact SAP.

  • Data Transfer Process and Infopackage

    Are both Data Transfer Process and Infopackage the same...Can someone please explain... thanks

    Hi,
    Pl search the forum for these questions as these are mostly discussed in the forums.
    or simply google it...
    Now IP is mandatory and used to bring the data from source to PSA..
    and DTP is loading and transfering the data within BI itself.

  • Need for Data Transfer process

    Hello Friends
    While loading data from ODS to InfoCube, do I really need to create a data transfer process or is there a way that the data loaded into ODS can be subsequently loaded into the cube after undergoing the transformation. If yes, please let me know how we can do that.
    Thanks and Regards

  • Issues in Data Transfer Process

    Hello All,
    After creating transformation from Infosource to InfoCube, now i am trying to data transfer process.
    In DTP Type it displays "DTP for direct process", but i need DTP type as Standard(Can be scheduled).
    Its giving me an error as "Source does not support direct access"
    Could any one help me to solve this error.
    Thanks in advance
    Regards,
    Nithin

    Hi,
    You can only use the type DTP for Direct Access as the target of the data transfer process for a VirtualProvider.

  • You are not authorized to display the data transfer process

    Dear Experts,
                          Good Morning!
                          I want to that I am getting one Message no. RSM906:"You are not authorized to display the data transfer process
    ".What does it mean .I want to load the data in the 0SD_C03 cube ,can able to load upto PSA but unable to create the DTP.IS this because of this messege of authorization or some other reason ,Request  you to please suggest me for this issue ,thanks in advance .

    Hi,
    You may not have authorisation for S&D cubes, so i feel it is an authorisation issue, kindly take one of your colleagues id to check this, if it is working for them, then i think you have to add those to roles to your ID..
    Still there is a option to override this, but you have debug it once, and change the authorisation code(sy-subrc) value, and please dont try this if you are not familiar at ABAP, and this is not adviceable if it is an authorisation issue as there will be logs recorded for all the things you are doing and oreover each time when u click on DTP you have debug it to change the authorisation
    code..
    Note: If it is QA or Dev system you can try debugging it, but if it is production system then i think u have to use an alternate ID...
