Extending an IDoc Type or Creating Custom IDoc type

Hi Experts,
We need to modify IDoc Type "DESADV01" for adding extra fields. Should I extend this IDoc Type or Create a new Custom IDoc type with the extra fields? Which is the best practice? This is my first time with IDoc functionality. Please let me know.
Thanks for the help.

Hi Dev,
Simple solution man.
Try to create an extension for the Idoc you wanted to extend.
Steps would be as follows: -
1) Go to WE31, create the z-segments and make them ready
2) Go to WE30, give some name for the extension and select the radio button extension and click on create button
3) It will ask you necessary details like which idoc you wanted to extend...Give the details and add the z-segments and save it.
4) Release it
Thats it.
Hope this solves your problem.
Thanks,
Babu Kilari

    Hi
    Data Creation in Idoc
    IDocs are text encoded documents with a rigid structure that are used to exchange data between R/3 and a foreign system. Instead of calling a program in the destination system directly, the data is first packed into an IDoc and then sent to the receiving system, where it is analyzed and properly processed. Therefore an IDoc data exchange is always an
    asynchronous process. The significant difference between simple RFC-calls and IDoc data exchange is the fact, that every action performed on IDocs are protocolled by R/3 and IDocs can be reprocessed if an error occurred in one of the message steps.
    While IDocs have to be understood as a data exchange protocol, EDI and ALE are typical use cases for IDocs. R/3 uses IDocs for both EDI and ALE to deliver data to the receiving system. ALE is basically the scheduling mechanism that defines when and between which partners and what kind of data will be exchanged on a regular or event triggered basis. Such a set-up is called an ALE-scenario.
    IDoc is a intermediate document to exchange data between two SAP Systems.
    *IDocs are structured ASCII files (or a virtual equivalent).
    *Electronic Interchange Document
    *They are the file format used by SAP R/3 to exchange data with foreign systems.
    *Data Is transmitted in ASCII format, i.e. human readable form
    *IDocs exchange messages
    *IDocs are used like classical interface files
    IDOC types are templates for specific message types depending on what is the business document, you want to exchange.
    WE30 - you can create a IDOC type.
    An IDOC with data, will have to be triggered by the application that is trying to send out the data.
    FOr testing you can use WE19.

    Create Segment ( WE31)
    Create Idoc Type ( WE30 )
    Create Message Type ( WE81 )
    Assign Idoc Type to Message Type ( WE82 )
    Creating a Segment
    Go to transaction code WE31
    Enter the name for your segment type and click on the Create icon
    Type the short text
    Enter the variable names and data elements
    Save it and go back

    An IDoc is simply a data container that is used to exchange information between any two processes that can understand the syntax and semantics of the data...
    1.IDOCs are stored in the database. In the SAP system, IDOCs are stored in database tables.
    2.IDOCs are independent of the sending and receiving systems.
    3.IDOCs are independent of the direction of data exchange.
    The two available process for IDOCs are
    Outbound Process
    Inbound Process
    AND There are basically two types of IDOCs.
    Basic IDOCs
    Basic IDOC type defines the structure and format of the business document that is to be exchanged between two systems.
    Extended IDOCs
    Extending the functionality by adding more segments to existing Basic IDOCs.
    To Create Idoc we need to follow these steps:
    Create Segment ( WE31)
    Create Idoc Type ( WE30)
    Create Message Type ( WE81)

    Hi,
    There are a dedicated BTEs (Business Tranaction Event) for this purpose (transaction FIBF).
    - created customer material infos OUTBOUND_CALL_00504001_E
    - changed customer material infos OUTBOUND_CALL_00504002_E
    - deleted customer material infos OUTBOUND_CALL_00504003_E

  • Creating Custom Content Types

    As the title suggests,  does anyone know how to create Custom Content Types in Adobe Livecycle Content Services ES?  I have looked far and wide across the www, and haven't had any luck with a straight forward, easy to follow, tutorial on the subject.  I have seen it for Actions and Aspects, but not Content.
    Thank you in advance,
    Alex

    Marc,
    Thanks for your response.  I've spent the past couple of days trying to get it to work, but I still cannot figure it out.
    According to all documentation I have found, I have modified the files I thought were the same as the Alfresco files:
    C:\...\jboss\server\all\deploy\contentservices.war\WEB-INF\classes\alfresco\extension
                   + .\liveCycleContentModel.xml
                        Added the <types> tag above the <aspects> tag, and created my type as specified online and also in a book
    Then I copied the web-client-config.xml to the extension folder and renamed as web-client-config-custom.xml and added the code to Content Wizards and Action Wizards to display it in the web ui.
    Am I missing anything?  When I re-package the .war file and redeploy/restart JBOSS, my localhost:8080/contentspace is completely broken.  no login in or anything but workspace is still in tact.
    Thanks for any further help,
    Alex

  • Create custom fault type in BPEL

    Hi
    Quick question for you all on a sunny Friday in London! Has anyone created a custom fault type in BPEL?
    If so, I'd appreciate a quick how to. I'm guessing it's a case of declaring a new type in your WSDL, but does it have to extend a type or something?
    Many thanks
    Chris

    From a rainy sunday eveving in Holland,
    You just create your own message type. Then you defien in your WSDL the fault, and point it to your own message type.
    In de BPEL process, you just name the name-space and use the Throw activity that uses your message type.

  • Create Contact Type in Create Customer contact screen of collections mgt

    Hi All,
    Can anyone please let me know if its possible to create a new contact type ( Currently we have four default types (Outbound call / Inbound Call / Visit to Customer / Visit from Customer) in the FSCM collections management, in the create customer contact screen.
    If its possible to create a new contact type, please let me know where to do that.
    Thanks in advance.
    Thanks
    Krishna

    You can add new contact types in the customizing table UDMV_CCT_TYPE.
    With this you would be able to select the contact types you have
    defined.
    Please note that you can create entries in this table only with the
    customer namespace i.e. prefix 'Z' to the contact type that you choose.
    e.g. if you want to create a new entry in contact type say 'TEST' then
    the entry in the customizing table should be as below:
    Contact type | Name of contact type
    Z03 | TEST
    Another point to note here would be that for each entry that you create
    in this table, the system displays 2 entries (1 for Inbound and 1 for
    Outbound) in the contact type dropdown on the customer contact screen in the collection management system. This is as per the standard design
    and it cant overridden.
    Thanks
