    Issue1:
    When I run change tracking as an iView through Portal , the logoff button on change tracking iView throughs null pointer exception.
    Issue2:

  • Error: Metadata of component EquipmentShipment is not valid!

    Hello all,
    I have created one webdynpro DC -A which has two DCs as used DC- B & C.
    Now everything builds & runs fine on local server. but when I activate DC "A" gives build errors, as it does not get reference for DC -B.
    Here is the error:
    "Error: Metadata of component EquipmentShipment is not valid! "Role "UsedComponent": A minimum of 1 object(s) is required!" "
    This error is only for "B" not "C"
    I tried rebuild, resync, recreate the dependency through public part but no use.
    Could you please help me with this issue?
    Thanks in advance!
    Regards,
    Sarika.

    Hi Sarika,
    Generally these type of errors occur due to broken DCs. Check DC build for 'B'. You may find more accurate information in the build report. I too faced similar issue once then the problem was some of the RFC changes were not imported. Check whether it is also same case for you.
    If it is a  wd-gen error, try to remove wdgen and gen folders for DC-B and build & try.
    Still you have problem, check this [thread |Re: Local DC problems;whether it can help you.

  • Where should i fire the plug within the webdynpro component

    when the search don't match for the url parameters passed in my scenario, i need to display the error view page, so wanted to know where should i fire the plug within the webdynpro component. could some one guide plz.
    thanks n regards
    Anoop

    You can go for event handling. In the component controller, just fire an event that there is a search mismatch. Handle this event in your view, where you just fire the outbound plug.
    Or, since you get the parameters in the url itself, instead of having 2 views, you can do it in one view itself by displaying only an error message when there is no record matching the query. If there are records, make the search results visible. Just have a context attribute to manipulate the visibility. This can be done with the comp controller itself, without any events.

  • How to find the webdynpro component on server

    Hi Experts,
              I need to identify a webdynpro component in server whether it is there or not. Just i know the name of the component, Why i am asking with that component i am getting some errors while created a callable object in GP. I need to identify the component and delete that.
    Is there any other  way to do this.......
    Please tell any one know how to find the component in server................
    Thanks,
    Sunil

    Hi ,
    To create a callable object from a web dynpro project you need three DC like
    caf/eu/gp/api
    caf/eu/gp/api/wd
    com.sap.security.api.sda
    but caf/eu/gp/api and caf/eu/gp/api/wd  are not available if you work on local development enviornment with out NWDI. Then you need to put those DCs within your local plugin directiory. I am sending you a link through this you will get to download those DCs and where you will put those DCs it is clear in this doc.
    https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/f7be53bb-0b01-0010-1c96-be3cb6799c1b
    In your local mc you will go to the following path
    Program FilesSAPIDEIDE70eclipsepluginscom.sap.tc.ap_2.0.0compCAFDCssap.comcaf
    here you will create a folder called eu and put the DCs as per the doc. and in SC u put your Toplevel SC.
    Now you try from Web Dynpro perspective. You will get all the DCs for callable object.
    Thanks

  • How to add a new url link in a view of an existing webdynpro component?

    How to add a new url link in a view of an existing webdynpro component?

    hi ,
    refer SAP online hep :
    Implementing Enhancements in a View
    http://help.sap.com/erp2005_ehp_04/helpdata/EN/46/233f2189f74f08e10000000a114a6b/frameset.htm
    To enhance the layout of the view, you can create new UI elements. This procedure is no different u2013 from a technical viewpoint u2013 from creating UI elements in components themselves. All UI elements created within the enhancement implementation can then be processed as usual.
    Enhancements  means inserting user developments into SAP development objects at predefined positions.
    The Enhancement Framework enables you to add functionality to standard SAP software without actually changing the original repository objects, and to organize these enhancements as effectively as possible.

  • How to call a RFC of a remote system from an ABAP webdynpro component

    Dear Experts,
    I am a newbie in ABAP Webdynpro.
    I am working on a requirement where I have a webdynpro component on ECC system.I need to call a RFC located on CRM system from my webdynpro component on the ECC system.
    How do I do that ?? Please help.
    Regards,
    Mamai.

    Calling RFC from some other system is same as local except the difference is that you have to give destination name while calling.
    And the regarding the method of calling it depends on your FM.
    if it is big RFC with complex structure, you can create the service call for it with destination given as RFC desitination.
    if it is simple straight forward RFC you can directly call it.
    for creating RFC service call call use this method
    1. Starting the Wizard
    To start the wizard, position the cursor on the Web Dynpro component to be edited in the object list at the left margin of the
    workbench window. Open its context menu and choose the entry Create->Service Call. The wizard is started and leads you
    through the creation process.
    Press Continue.
    2. Choice of Controller
    On the second dialog window of the wizard, you can choose whether the service call is to be embedded in an existing
    controller or whether a new controller is to be created for this purpose. Service calls can only always be embedded in
    global controllers u2013 that is, in the component controller or in additionally created custom controllers. It is not possible, to
    embed service calls in view controllers.
    a. Select radio button Use Existent Controller
    b. Do not change the default entry for component: <CC name>
    c. Enter for controller COMPONENTCONTROLLER
    d. Press Continue.
    3. Service Type and Service Selection
    a. You now select, which service type should be used for this service call. Select radio button Function Module. Fill the
    destination here. Press Continue.
    b. Select the service: for Function Module enter <RFC name>. Press Continue.
    4. The Required Methods and Context Elements
    On the two subsequent dialog windows, default values are listed for giving names to the context nodes and attributes
    required by the service call as well as to the required methods. The proposed names are based on the names of the
    embedded service, but you can change them as required. However, heed the respective notes in the corresponding dialog
    box.
    a. Adapt Context: Select from Nodes/Attributes . Press Continue.
    b. Specify Method Name: leave all entries as provided: Component:  Controller: COMPONENTCONTROLLER Method: EXCUTE_ Press Continue.
    5. Completing the Choice
    When you have confirmed the last dialog box, the generation is triggered. Afterwards you now have the required methods
    and contexts at your disposal for using them within your Web Dynpro component.
    or if you want to call directly the use the call statement with destination

  • Consuming webservice in a webdynpro component

    If possible, Provide me some good material for consuming webservice in a webdynpro component.
    Awaiting for a useful reply.

    hi,
    Few indroductory sessions
    /people/thomas.jung/blog/2007/12/17/consuming-services-with-abap -Consuming webservices with webdynpro.
    It is possible to create webservice in ABAP as well as in Webdynpro.

    In Web Dynpro ABAP there is nothing special about calling a web service. Unlike WD Java, there are not dedicated model object types in WD ABAP. WD ABAP simply has the ability to interact with other ABAP development object types. You can call function modules, ABAP classes, even modules in old dynpro apps.
    So calling the webservice from ABAP therefore is just the process of generating the ABAP Proxy Class. This is the same process regardless of if you want to use this proxy class from WDA or any other type of ABAP development object. You can then call the proxy class from WDA just like any other type of ABAP class. There is a service wizard option in later support package levels that includes an option for ABAP Proxy classes - although it doesn't generate the proxy class it just generates the code and context for the call to an already existing proxy class. The service wizards in WD ABAP are not required however. They are just shortcut code generators and often can't even generate a complete context for a complex web service proxy - so expect to do some manual adjustment after running the wizard.
