Navigation in Web Dynpro for ABAP

Hello Experts
I have a problem with triggering navigation to external Web Dynpro application.
Here is the current set up. I have multiple Web Dynpro reports using custom authorizations (utilizing Z-table, checking application name and user ID). In case if authorization check fails I am triggering plug which takes user to view with u201CNo authorizationu201D sign. Works perfect. Problem is that I have to embed this u201CNo authorizationu201D view on each report.
Now, I tried to do following but I failed. I have created Web Dynpro application only with u201CNo authorizationu201D sign (single view). On each report I was calling static method that checked authorizations and in case if it was not successful I was executing absolute navigation using method NAVIGATE_ABSOLUTE of IF_WD_PORTAL_INTEGRATION instead of firing plugs. Unfortunately no navigation has been triggered (method has been executed). Please note I am not using any portal integration. Each report is just a separate Web Dynpro application. Perhaps that is the issue.
Is there a way to re-direct user from one Web Dynpro application to another using ABAP code?
Kind Regards
Michael

> Perhaps that is the issue
Yes that would be the problem.  You can only use the Portal Navigation APIs (IF_WD_PORTAL_INTEGRATION ) when running in the Portal or in the NetWeaver Business Client.
> there a way to re-direct user from one Web Dynpro application to another using ABAP code?
Yes - exit plugs would be the correct approach.

    If you do not yet have a user ID, contact your system administrator.

    did you check the short dump message in ST22, maybe gives you some additional information.
    But when looking at the message, I would say that in the FLIGHTLISTVIEW node flight_list is not created.
    Check if node is available, also check the name of the node. Maybe a typo  (fligth_list, or flight_lits, or...)somewhere.

  • Offline Interactive Forms (Web Dynpro for ABAP)

    Hi Everyone.
    Please help me!!!
    Upload Offline PDF file to xstring context attribute by file upload in Web Dynpro parts.
    Set Offline PDF file uploaded via xstring context attribute in 'pdfSource' property of interactive form.
    I wish to view Offline PDF file and get data to context in 'dataSource' property of interactive form.
    Below restriction.
    - Web Dynpro for ABAP
    - Offline Interactive Forms
    - Zero Client Installation
    - ABAP Dictionary-Based Interface
    NetWeaver 7.0 (NW 7.0) SPS16

    Hi Daisuke,
    As per your requirement, to get done your work you need to create two Adobe Forms , one is for Offline Interactive Form and other is Online Interactive Form.
    In offline Interactive you design your form and define the Layout type as zci layout and Abap Dictionary Based interface. And by executing the form you can save the form to your desktop.
    Now in online Interactive Form you create the context similar to the one which has been created in the Offline Interactive Form. Now in one view you define the file upload functionality and in other view you define the adobe interactive form, for this the interface is automatically as it asks for the context and its of type XML based interface, also do maintain the context variable something like "PDFDATASTRING" with type XSTRING in the Component Controller and now in adobe view you give the property pdfstring as "PDFDATASTRING" and dont forget to provide the navigation of these two view, and set the File Upload View as default view.
    The above functionality can help you in some way or the other.

    I think you are overestimating the power of the SCM_STRING_TO_XSTRING function module.  By supplying a URL as the value of the input text, it isn't going to magically go read the content from the remote location and convert that to a binary string.  It is going to take whatever value you supply in th importing TEXT parameter convert that to binary.  In other words it is literally converting the string http://xxx/test.xls to binary.  You will need some other mechanism to read the content from the remote location into ABAP memory before you can process it.  You will need to use the CL_HTTP_CLIENT class or call some sort of web service to retrive the content.

    Hi,
    Use a Transparaent container (TCO) inside it use the tabstrip and make it as matrixheader as per rootUI.
    You can also set the layout for TCO as matrix and do the necessary changes.

  • Framesets in Web Dynpro for Abap

    Hi all,
    I have a question concerning framesets in Web Dynpro for Abap. Today we have a BSP application with 3 framesets: a header-view, a navigation-view and a main view. We'd like to create the same application in Web Dynpro for Abap. I know this is possible in Web Dynpro for Java; is it also possible in WD for Abap or does someone know an alternative?
    Many thanks in advance!
    Siegfried

    The idea of creating viewsets withing WDA was removed.  Instead just create a view to control your layout.  Create viewcontaineruielements to withing this layout view to control the arrangement and positioning of the inner views.

  • Web Dynpro For ABAP Question

    Hi all,
    I'm creating Adobe Interactive forms in Web Dynpro for ABAP.
    <b>Problem:</b>
    <b>Context defined in the created "View" is not displayed in the 'templates' (Adobe Interactive Form in the "Data View" tab.</b>
    I'm following the exact steps used in the following e-learning class:
    <b>https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/media/uuid/c766e918-0b01-0010-99b1-c2b78cd059b3</b>
    Except I'm creating 'string' fields instead of numeric fields like in the above e-learning class and creating my forms in Adobe Livecycle designer first then importing them to the web dynpro for abap - 'templates'.
    The 1st form I created went well and works fine.
    <b>Question:</b>
    For my second and third form I'm unable to map my context fields they are not displayed in the "Data View" anyone know why this is not possible?
    Cheers,
    Dharm

    Hello,
    are you creating the form via forward navigation from webdynpro abap?
    When you do that the context of the form should be created automaticaly.
    What Basis SP level are you using?

  • How to debug Adobe form attached to Web Dynpro for ABAP

    Hi,
    My developer has created an adobe form and rendered inside a Web Dynpro page in the SAP Portal. It communicates with the Web Dynpro framework in the backend SAP system (Web Dynpro for ABAP).
    My question is, how would I know what infotype access this form requires, in the form of backend authorization role? Is there any way (not trace, ST01) to debug Abobe form on Portal or in backend SAP system?
    Thanks,
    Karan.

    Julius Bussche wrote:
    > I am not sure whether this will work in this case, but principally if your trace is recording a * value for a field in an authorization check, then it must be defined somewhere, and there is an option in the trace file to jump from the check to the source code location where it occurred.
    Yes, that's possible since the trace also records the information on the ABAP source code location where the AUTHORITY-CHECK statement (or other ABAP statements which internally trigger authorization checks) is executed. If I'm not wrong then there is a button (in ST05) which allows a direct source code navigation. Alternatively you might just click on the ABAP source code information displayed in the ST05 trace results (for recorded authorization checks).

  • Direct link to Web Dynpro for ABAP

    Hey everyone,
    I created a web dynpro    for ABAP    application that will list out all the work items for the purchase requisition approval through workflow. I want to be able to have our higher ups be able to access this through our portal. I created an iView    that works and calls the application just fine.  What I want to do now is provide a link in an email to these people so they will be able to log into the portal and go directly to the application (just the application not portal wrapper around it at all) and only the application.  I can't provide a directly link to the WDA app since, I think, it would be to the ECC server and not the portal one.
    I have tried Quick Links but that isn't what I want.
    I did try to put a pcd location link
    http://<server>:<port>/irj/servlet/prt/portal/prtroot/<pcd location>
    but I get an internal error because it's trying to do an anonymous login and I want the login screen to show up first.
    HELP!!!!!
    Thanks,
    Archie

    The PCD path of the portal object is the Navigation target.
    http:/myServer:50000/irj/portal?NavigationTarget=ROLES://portal_content/myFolder/myRole
    This can be hashed and shortened to form the Short URL as shown below
    http:/myServer:50000/irj/portal?NavigationTarget=navurl://b3d6d9ebac16a46574d62757803b05d4
    Short URL can be enabled and disabled depending upon the requirements.
    Check the links below for detail description to enable short URL:
    http://help.sap.com/saphelp_nw70ehp2/helpdata/en/43/014421d21d6fade10000000a11466f/frameset.htm
    http://help.sap.com/saphelp_nw70ehp2/helpdata/en/49/330b66fd695aa8e10000000a42189d/frameset.htm
    NavigationTarget generally shows all the portal roles with the specific object highlighted.
    In the sense it takes you to that Object with the portal header and TLN.
    If your requirement is not to show header and TLN,then try adding &NavMode=3 to the NavigationTarget url you are using as below
    http://<server>.<port>/irj/portal?NavigationTarget=ROLES://<PCD path of object>&NavMode=3
    I( made some testes here, and works fine for worksets and roles.
    Hope it Helps.

  • N4S: Web Dynpro for ABAP layout editor not working

    Have problem in Layout editor in Web Dynpro for ABAP
    I have installed NW04S Testdrive on 64bit Linux and able to login.
    SE80 is working alright.
    Next I create a Web Dynpro Comp. / Intf. and create a component.
    I double click on the View name "V_Default" . The Layout editor opens on the right side. Change into Edit Mode.
    The "View Elements" panel on the left side of layout editor is missing. This is where we select the various elements like "Textview" etc.
    Even the right click on the "ROOTUIELEMENTCONTAINER" to insert elements using context menu does not work.
    In summary I am not able to add any element in WD4A Layout screen.
    Is there any special plugin required to be installed?
    How to solve this problem?

    you cannot develope Webdynpro for ABAP using ECC5
    This is available with netweaver 2004s (WAS7.0) for which ramp up is going on right now and the general availability is expected sometime around 1st quarter for 2006.

  • Import Data from Office Control (Web Dynpro for ABAP) into internal-Table

    Hello,
    I have a question concerning the Office Control UI-Eelement in Web Dynpro for ABAP:
    How can I import spreadsheet data from the Office Control into  a internal-table?
    I have an Excel-sheet (without any data) which is shown initially in the Office Control. First the empty Excel-Sheet will be loaded and in the second step data from an alvxml-transformation will be loaded into the Excel-sheet with the method 'activatexmlsource'. This works so far. When I change the loaded data in the Office Control and save it it will be stored as XLS-File. The problem is that I'm not able to use existing Upload-FM because every function module I tried uses GUI-functions and WebDynpro has no GUI-functionality. I always get the error that data from clipboard cannot be imported.
    So now the question is:
    How can I import changed data from the Office control into a internal-table staying in Web Dynpro application?
    Please give some advice, if you have some useful code or ideas.
    Thanks

    Hi,
    Once you save to desktop again you have made some changes to that file, this file you want to upload it right.
    Then in that case you need to use the FILEUPLOAD UI element right.
