  • BW Workbook as an iView in the Enterprise Portal

    I keeping getting a dialog box asking to select the appropriate program to open the workbook. When I select .xls it opens, and it shows the parameters I entered and not the workbook. The customer is on NW04 Stack 11.
    I followed ever step on help.sap.com site as listed below.
    BW workbooks are MS Excel workbooks with one or more embedded BW queries. You are able to display these workbooks in the Enterprise Portal as iViews.
    Features
    Workbooks are displayed in a separate MS Excel window. Opening workbooks within the Web browser window is not possible for technical reasons.
    BW workbooks require the BEx Analyzer, which requires a local installation of the SAP GUI for Windows with the BW front end.
    SAP recommends that you use BEx Web applications in the Enterprise Portal that run completely in the Web browser.
    You can use the function Export as Excel 2000 File from the BW Web application context menu as an alternative to using a local installation of the BW front end if you require Excel functions. See Context Menu Functions  and Exporting as a CSV File/Excel 2000 File.
    An iView with a workbook can be generated using the Portal Content Studio or Role Upload. For more information, see Generating Content from SAP BW for the Enterprise Portal.
    The iViews are of type SAP Transaction iView and have the code link com.sap.portal.appintegrator.sap.Transaction.
    The most important properties are System, Transaction (TCODE) and ApplicationParameter.
    ·The System property contains the alias on the BW system (see Creating BW Systems in the  Portal).
    ·The transaction code for every workbook is RRMXP.
    ·The value WBID= is in the ApplicationParameter property.
    You can determine the workbook ID with the BEx Analyzer:
    a. Open the desired workbook.
    b. In the BEx toolbar, choose ® OLAP Functions for Active Cells ® Properties. The Information tab page contains the Workbook ID (Server).
    Note that with BW workbooks as an iView, the AutoStart property contains the value True (process first screen) and the GuiType property contains the value WinGui.
    Anyone have a solution for this to work?
    Thanks,
    -Eli

    Dear Rasmesh,
    Please try to do this suggestion:
    3. How can I use SAP Application Integrator to access SAP transactions?
    There are two different ways to use the SAP Application Integrator transaction iView. In both cases please use a URL like 'irj://com.sap.portal.appintegrator.sap.Transaction' followed by your custom parameters like '?System=DEV&TCode=SE38&GuiType=WinGui &WinGui_Type=Shortcut&OkCode=SHOP'.
    The parameters are:
    System [mandatory]
    TCode [mandatory]
    GuiType (=WinGui / WebGui / JavaGui) [mandatory]
    WinGui_Type (=Shortcut ..if you want to launch the GUI in a new window)
    OkCode (The OkCode that you would like to be executed after the transcation is called by SAP GUI.)
    ApplicationParameter (Pass these values to your screen fields which needs to be be separated by
    AutoStart (true / false)
    UseSPO1 (true / false)
    For a complete list of parameters please consult http://help.sap.com.

    Hi,
    All the requirements is  to build of the header bar (branding bar) in  the Enterprise Portal.
    Currently when I click in left nav  , the SAP EP Links open up in new window.
    These pages do not have any Company  Branding header on the top.
    I am required to put Branding header  on these EP Pages and call them on to MOSS UI.
    Plz refer the solution to me.
    Thanks,

    Dear Sanjay ,
    Please clarify the below points so that we can understand exactly what issue you are facing .
    1. " requirements is to build of the header bar (branding bar)"  --- Are you referring to the portal  MastHead ?
    (typically mastheadincludes -- welcome "name of user who logs in " , Branding Image - horizontal image bar, help , log off n personalize button"
    2. "when I click in left nav , the SAP EP Links open up in new window. "
    In the left Navigation what are you clicking , what exactly is opening in a new window .

  • How to bind an IIS to the enterprise portal installed on a linux machine

    Dear all,
    I am very new to the topic of Enterprise Portal.
    Our intention is, to develop .NET IViews and deploy them in the Enterprise Portal.
    The Enterprise Portal Server is set up on a linux machine.
    The Guy who did install the Portal Server, has no idea how to "integrate" the Microsoft IIS to the Portal.
    After deploying my .net Component, i tried to view this component in the portal (by right clicking the mouse on the Component in in the .NET Solutions Explorer).
    This gives me the following error:
    Portal Runtime Error
    An exception occured while processing a request for:
    iView:N/A
    Component Name: N/A
    Could not find portal application com.sap.portal.dotnet.framework.
    Exception id: 02:06.......
    See the details for the exception ID in the log file
    I think that this has something in common with integrating the IIS on the Linux Machine, and maybe additionaly installing the pdk.net on the IIS webserver machine which should be used.
    Thank you for your help.
    Regards

    Hi,
    Welcome to the world of Enterprise portal
    Seems to me like you are trying to use the PDK for .NET. If so - Please read the overview section in the documentation to get a general idea of how it works (for example - IIS is not used at all!).
    See the Visual Studio integrated help or click this https://media.sdn.sap.com/html/submitted_docs/dotnet/index.htm
    there go to "Getting Started" and mostly "Overview".
    Anyway, It seems like the problem is that you didn't deploy the 2 required SDA's to the portal. You should also take a look at the "installation and configuration" guide. Download it here: https://www.sdn.sap.com/sdn/developerareas/dotnet.sdn?contenttype=url&content=/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/documents/a1-8-4/pdk for .net administrator guides.zip
    Good luck,

  • Windows Applications in the Enterprise Portal

    Hi all,
    we have EP 6.0 SP10 based on NW04 installed.
    Is there any possibility to integrate Windows Apllications
    (Windows 'exe' files) in the Enterprise Portal.
    Best regards

    With LaunchInIE you use JavaScript to launch the actual applications. What we do is write a Java iView that contains links (we use icons) to programs installed locally on each machine. When the user clicks a link (icon) we run the JavaScript that opens the locally installed 'exe' file.
    If you have a look at the WhirlyWiryWeb link posted earlier you can see how to use LaunchInIE.
    The downside to this is that the .dll has to be installed on each machine and the registry (for each machine) has to be maintained.
    You can just write a java iView that has links to locally installed exe's (file://C:/myfolder/myexe.exe) if you like but that will result in a security warning each time. LaunchInIE stops the security warning.

  • Use HCM processes and Forms without using the Enterprise Portal

    is it possible to leverage existing HR Admin Services (HCM processes and Forms) functionality without using the Enterprise Portal?
    1) Create an Adobe form and Interface using SFP
    2) Set up ISR and Form Scenario
    3) Set up Forms configuration to use existing Backend and generic Services
    4) Set up workflow to updated Backend using Services
    is it possible to do the above steps and not use the Portal? If Yes, how do we present the forms to the Manager, and provide different buttons that appears on the Portal by default?
    Any ideas will be greatly appreciated.
    Thanks,
    Saurabh

    Hi Saurabh,
    your assumptions and findings (items can not be started from the backend workflow inbox etc.) are correct: These processes can not be started without the Portal and it is not intended to do this.
    The above mentioned backend report are only forseen for implementation and testing purposes and not for productive use.
    In addition to the fact, that you already can't execute the work items a lot of other features of the framework (Process Browser etc.) are only available through the Portal.

  • Difference between using the Enterprise Portal and SAP GUI

    Hi Gurus,
    Could one of you please send me a document that lists the differences between the Enterprise Portal and SAP GUI?
    thanks in advance

    Hi,
    For groups, managedBy is an administrative convenience to designate “group admins”. Whatever principal listed in
    managedBy gets permission to update a group’s membership (the actual security is updated on the group’s AD object to allow this).
    In Win2008 and later managedBy also became the way you delegated local administration on an RODC, allowing branch admins to install patches, manage shares, etc. (http://technet.microsoft.com/en-us/library/cc755310(WS.10).aspx). 
    On the RODC, this is updating the RepairAdmin registry value within RODCRoles.
    So the difference between them should be only the way they do the same thing.
    For more details, please refer to the below article:

  • Upgradng the enterprise portal from non HA to HA

    Dear Experts,
    We have Enterprise portal 7.01 on windows 2003 with db2 9.1. and 1 dialog instance. presently it is not in HA. We want to change this to HA using MSCS.
    Can any body share some knowledge on this. How to change the existing system.
    thanks alot

    Hi,
    I must want to correct this question as
    " Migrating the enterprise portal from non HA to HA".
    The only option i can see is reinstallation or i mean to say system copy to new HA system.
    Yoy have to plan your connectivity issues in case you are going to change hostname,IP etc.
    Steps:
    1) Install Fresh HA EP system
    2) Take export from source EP system and DB backup
    3) Perform system copy steps on new system
    4) In case host name is changed , inform the respective interfac eowners.
    Hope this will help you to plan better.

    Hi Björn,
    you can access request parameters with the following code in the standard methods of your Portal Component:
              // IPortalComponentRequest request;
              request.getServletRequest().getParameter("ParamName");
    The direct URL of your Portal Component without a specific iView is:
    http://
    If your component should be directly accessable without authentication you must add the following property in your portalapp.xml in the the component-profile section:
          <component-profile>
            <property name="AuthScheme" value="anonymous"></property>
          </component-profile>
