Dynamic navigation structure

Hi all,
I want to implement a dynamic navigation structure that displays navigation nodes depending on the status of the user in the backend system.
The scenario is as follows:
- user gets access rights via roles and profiles in backend system
- each user is assigned to a business partner in the backend system
- each business partner is in a specified phase (the phase of a business partner can change over time)
- a table in the backend system contains the mapping: phase - visible navigation structure
-> in the portal the user should see only these navigation nodes, that are set to visible in the mapping table, all other navigation nodes are hidden
Is it possible to implement such a behaviour?
I'm running EP 6.0 and CRM 5.0 as backend system.
Thanks in advance.
Kind Regards,
Martina

Hi Martina,
Filtering out roles and worksets can be done by implementing a role filter, for details see https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/ep/code-samples/filtering%20role%20and%20workset%20content.htm and https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/5021a57d-0601-0010-6097-ec94a09c626d for example.
> in the portal the user should see only these navigation nodes,
> that are set to visible in the mapping table, all other navigation nodes are hidden
Of course, these nodes must be a subset of the navigation nodes the user has per role assignment.
Hope it helps
Detlev

  • Implementing a dynamic navigation

    I want to include dynamic a navigation structure under a specific role into the navigation of the portal. The navigation structure should consist of an XML file. The link should opened in the mittle of the portal (content area).

    Hi Mario ,
      Two steps are involved here in implementing dynamic navigation which is role based .
      1)  Creation :   Right click on the Iview/Page  where  you can find one properties name as Dynamic navigation open it and assign any iview that you wish to see in the left navigation panel
      2) Assign :  Now you assign the above created iviews to the role .
      Hope this will be your result .
    Thanks  & Regards ,

  • EP6: Dynamic Navigation - Eventing

    Hi everybody,
    I want to navigate to the same page/iView from my dynamic navigation nodes (which implement INavigationConnectorNode). The dynamic navigation shows a list of customers. Clicking on one of them should show the same page/iView, obviously for different customer ids.
    Trying the simple approach to append the parameters ("....?customerid=4711") to the launchURL does not work.
    I assume the whole concept works differently: do I have to implement getPRTEvent() (or maybe getJScript() or ..) to parameterize my navigation event ?
    I cannot find any info on that subject, so I'd be really grateful for ideas and hints.
    Cheers,
    Heiko

    Hi Altafin,
    thanks for your reply, unfortunately this does not work: you assume that I build an iView and thus can control the HTML output. What I do, though, is to dynamically build a navigation structure (not in an iView but in a Navigation Connector). There I only have a couple of fields I can set, most notably the "launchURL". The standard Portal Navigation Service takes my data structure, merges it and forwards it to the (standard) detail navigation iView.
    In the meantime I have been able to solve it (actually thanks to Sven Kannengiesser): I put the following into my launchURL:
    "/irj/servlet/prt/portal/prtroot/<escaped pcd url>?myparam=4711"
    where the escaped pcd url looks something like
    "pcd!3aportal_content!2fmyfolder!2f .... !2fmypage"
    That works fine.
    Cheers,
    Heiko

  • Changing the Portal Navigation structure

    Hello everyone,
    I am also trying to modify the Portal general look and feel. I want to change the portal navigation structure (not just the themes and templates) the way first and second level navigation has been arranged. Do you have any idea as to how to do this?
    One example could be, can I center all the second level navigation items. Can I modify the tab separators etc.
    Would appreciate any help.

  • Portal Runtime Error in Dynamic Navigation Area

    Hello gurus,
    In our production portal all of sudden we are getting a portal runtime error in Dynamic Navigation Area.  Earlier there was a problem with one of the clustered nodes and it was resolved.  I was wondering if this error is in connection with that.  Has anybody faced such problem?  Following is the error we are facing in the dynamic navigation area.

  • WD Java iView & Dynamic Navigation Problem

    Hi,
    I'm trying to use a WebDynpro Java iView in Dynamic Navigation but have the following display problem:
    When I navigate to the page for which I've added the iView to the dynamic navigation, only the WebDynpro iView (from the navigation) is shown. You can see the page in its correct form being loaded but as soon as the navigation iView seems to be loaded/ing it replaces the full lower part of the screen (navigation and content panel).
    If I use a plain URL iView in the dynamic navigation the behaviour is as expected.
    But if I add a WebDynpro iView or even a page containing that iView I get the strange behaviour again.
    I'm running NW04s SP7.
    Any ideas?
    Do I have to set some properties on the WebDynpro iView?
    I've tried a couple of things but none did work so far.
    Thanks & Regards
    Markus

    Hi Henrik,
    Sorry for the late reply but I'm just back from vacation.
    No, I have not found a solution. I decided to go for an integrated application instead (Main WD application that bundles navigation with other applications). That works but of course is not as "nice".
    Have you come across some solution yet?
    Kind Regards

  • Employee Search in Dynamic Navigation does not update other iViews (FPM)

    Hi all,
    after selecting a person from Employee Search (MSS) we have to display corresponding data in a customer specific iView with help of selected person number.
    So I created a Floorplan Manager Application as described in https://www.sdn.sap.com/irj/sdn/wiki?path=/display/profile/how-toaddacustomWebDynproiViewtotheMSSEmployeeProfile%28ECC+6.0%29&
    If I use the SAP content page or create my own pages with corresponding Employee Search and customer specific iView, updating of data on the customer specific iView works. But if I add the Employee Search to Dynamic Navigation, the data is not updated in the customer specific iView.
    I didn´t find a solution in this forum. Does anybody know, if it is possible to add the Employee Search as Dynamic Navigation (with help of Floorplan Manager functionality) and update data in other iViews and how this works? Or is it possible to handle this in a different way, e.g. PortalEventing?
    Thanks,
    Thomas

    Hi,
    I also tried to use only iViews of 'General Information'  and added the employee search (team viewer) of the sap
    content page 'General Information' to the dynamic navigation, but the other SAP standard iViews of 'General Information' page are not updated, too.
    Does anybody know, if it is possible to add the employee search to dynamic navigation and to update the other iViews of 'General Information'? If yes, what properties have to be set? Are some settings for Floorplan Manager
    needed?
    Could anybody please give me a hint?
    Thanks,

  • Understanding Dynamic Navigation iview.....

    In MSS, I have the following workset in my role...
    ->Team (workset)
       ---+ Team (webdynpro proxy page)
       ---+ Employee information (folder)
       ---+ Employee Working Time (folder)
       etc....
    The "Team webdynpro proxy page" has an iview ,"Services", assigned in "Dynamic Navigation" but there is nothing particular about that iView itself. However, all folders (and their contents) below the Team webdynpro proxy page appear in the Dynamic Navigation panel (like "Employee information" and "Employee Working Time"). I do not understand the connection between the dynamic navigation iview and how all folders in that workset know to display in that dynamic navigation area. There seems to be no explicit assignment. How does that work?
    edit: a bit more info....the "Services" iview is part of the Common Parts business package and based off the "related services" iview template. Still not sure how it "knows" to display the objects below that page that has it assigned as dynamic nav.

    Did you blog about this solution?  If so could you direct me to the blog?  We need to add numerous links to outside URLs in Related links.  I need to order them somewhat differently than alphabetically.
    Thank you,

    Posted: Aug 29, 2005 3:03 PM        Reply      E-mail this post 
    Hi
    I have an iview from BW that generates links to reports. I associated this iview to a page as a dynamic navigation link.
    When I click on the link, it does not load the content in the portal content area. I tried _self, _top, _parent as the targets in the BW web template.
    How can I get the content loaded in the portal content area? What is the name of the portal content area frame?
    Thanks
    Sriram

    Hi Sriram,
            I confronted with the same issue as yours but then i did the following.......
    Presuming that two iviews are already created i.e.
        1.Navigation Panel iview with links (left)
        2.different iviews associated to the links.
    Now,
         >>Open the other iviews and select Dynamic navigation in the context menu.
         >>Right click on the navigation panel iview having the links and select "Add to Dynamic Navigation"
    In the first iview for the link the code i gave is
    <a href="link2" class="urLnk" onclick="return EPCM.doNavigate('ROLES://portal_content/xyz/Pages/sampleiview')">Link to Project Plan</a>
    No need of the parent,self,.....etc.
    Hope this helps.

  • Dynamic Navigation in ES

    Has anyone tried to add dynamic navigation to ESS page? My issue is after I click the links on the page to launch the service (e.g. Working Time: Record Working Time Service), dynamic navigation is lost.  Please suggest.  Thanks,
    Rong

    Hello again,
    thanks for your support. It was all my fault that the dynamic navigation didn't work. I've already added the Dynamic Navigation iView to the Framework-Page, but forgot that I made objects invisible by default for that specific container that I added the DN iView to. So making contents visible for this container worked.
    Anyway, Karsten's link might be very helpful for future Layouts. But for this specific layout the customer explicitly wanted the old default framework behavior for the dynamic navigation.
    @Detlev Knowing where to find that code is very good. Actually it's not that self-explanatory and I didn't find out how the DN works in the AFP, but thank you anyway. We've never worked with the AFP before and maybe I didn't phrase my question clear enough. Maybe that's why none of the colleagues I've asked were able to answer my question.

    René
