Disable multiple logon from SAP NetWeaver Portal

Hello
I'd like if there is a parameter inside SAP NetWeaver Poral to disable multiple logon with the same account(like login/disable_multi_gui_login for ABAP).
Thanks in advace
Regards
Stéphane

Look at service.sap.com
This authentication only works for S-users (as well as SAP employees) who are active accounts in SAP's AD. That works via the internet for SAP customers and employers (e.g. from each other's networks but their own devices) as well.
With a SAML IdP you have a lot more flexibility in choosing the source of the first authentication and managing complex access rights through to the backend.
But you are correct: if there are not too many users to manage and they are smart enough to periodically generate a client certificate and they are physically attached to their own personal devices, then a Certificate Authority or even Open SSL solution is another option.
I guess it would be usefull to know how many users there are and how the authentication through from the NW portal to the ABAP backend system is going to replaced. Also how much user context information is needed on the backend system still, if at all anymore.
I think we need more information here still before we can safely conclude that a client certificate is appropriate for an internet scenario.
I am more worried about all those issues like stolen certificate and so on.
From my SDN experiences it is more often a case of people loosing their certificates and user IDs than one of other people stealing them.. The vaste majority of the 2 million users are using passwords and those who are active seem to be happy with the password reset service --> also an option.

Run a Crystal Report published on BW from SAP NetWeaver Portal without BOE

Hi all,
We need to create a report using Crystal Reports, save it to BW, publish it to SAP NetWeaver Portal, and run it from SAP NetWeaver Portal. We do not want to use BOE here.
Currently, we are able to save the report on BW.
With Xcelsius, we have seen that we can directly refer to the dashboard's technical name from SAP NetWeaver Portal. Is similar thing possible using Crystal Reports? If yes, how this can be achieved?

Dhanesh Aradhye

but you still need the BusinessObjects Enterprise system as only the BusinessObjects system will actually render the report.

Publish Crystal Reports to SAP NetWeaver Portal

We are trying to publish Crystal Reports to SAP NetWeaver Portal. So far we found that we always have to save to BusinessObjects Enterprise first, and then we found the ID from Crystal Reports in the InfoView. After that, we put that ID in our iView using PAR template. Here are our questions:
(1) After we save Crystal Reports to BW server, how can we run that report from BW without saving to BusinesObjects Enterprise?
(2) Can we directly publish Crystal Reports to SAP NetWeaver Portal without saving to BusinessObjects Enterprise first?
Thanks a lot for your answers!
Paul

Thanks for the answers. From your answer, I believe what you are trying to say is that we need to save Crystal Reports to BusinessObjects Enterprise no matter what. We need to save Crystal Reports to BOE first, and then we need to have BOE in order to run Crsytal Reports.
>> Yes
Then we can publish our Crystal Reports saved in BOE to iVew in SAP NetWeaver Portal. Wether we save Crytal Reports to BW is not necesary.
> correct. That is your choice but remember that saving to BW does come with benefits such as an integration into transports.
This also means that we cannot just create Crystal Reports, save it to BW, publish it to SAP NetWeaver Portal, and run it from SAP NetWeaver Portal w/o BOE. Please correct me if I am wrong
>> correct

Integrating a Java web application into the SAP NetWeaver Portal

Hello experts,
We have a requirement to integrate a Java based web application into the SAP NetWeaver Portal using iView/iFrame technology. The Java based web application is completely independent from the SAP environment but should be displayed as part of the SAP Portal environment. The other requirement is the main navigation menu for the Java based web application should be configured and provided in the SAP Portal.
Any pointers on how exactly this can be done would be of great help.
Also how can the SSO (Single-Sign-On) to the Java application be implemented so that the user can logon to the java application through the portal without providing the user credentials again.
Thanks in advance.

Hi,
I think you can use URL iviews to integrate your java web application with EP. you have the option of doing SSO with the application as well.
Have a look at the sap help material

How to connect SAP R/3- System with SAP NetWeaver Portal (2004s)?

Hello to all,
sorry, can someone help me? How can I connect SAP R/3- System with SAP NetWeaver Portal (2004s)?
Thanks and regards,
Galyna

Hi,
In previous link contain this info
This describes how to connect an SAP R/3 system to SAP NetWeaver Portal using an iView
1)      Go to System Administration
2)      Go to System Configuration
3)      Go to Portal Content (Right Side Panel), open that folder.
4)      Right Click on Portal Content, a Panel is displayed select "System (from Template)".
5)      That will display a new view on right side, now select "SAP system using dedicated application server" from
the existing templates. (Other templates are possible - for example, load balanced or through a SAProuter connection string).
For this exercise, we'll use the simplest type.
6)      Choose next
7)      Give the System Name and System Id (which are mandatory fields) incase you want to give any brief notes
about the system then give them in the "Description" field.
8)      Open the Newly Created System.
9)      Now when you want to create a New System, you have to fill four Properties they are:
"Connector" - contains basic connectivty details
"Internet transaction Server (ITS) - if you wish to use SAPGUI for HTML and/or IACs",
"Web Application Server" - if you wish to access BSPs and/or Web Dynpro for ABAP and
"User Management".
You also need at least one "System Alias" has to be defined from the Display drop down menu.
Make sure you have set end user access in the Permissions drop down menu to all users who need to access the system
10) Select "Connector" property, now fill the required fields such as:
a)      Application Host (should be fully qualified hostname) - Give the R/3 "Application Name",
which can be obtained from the SAP Logon Pad (check what R/3 system you are using, right click on it , go to the properties,
it will open a window which has the Application Server Name.
b)      Logical System Name - Give the logical name as defined in the backend system
c)      SAP Client - Check the Client in the backend system and give the appropriate number (3 digits)
d)      SAP System ID(SID)* - Check the R/3 properties and give the check for System ID
e)      System Type* - Since we are connecting to R/3, select SAP_R3 system.
f)       System Number - This is a two digit number that you can find in the SAP Logon Pad
11) Select "Internet transaction Server (ITS)" property, now fill the required fields like
a)      ITS Description à Give some Description
b)      ITS Host Name - Same as "Application Host" of R/3 (when integrated ITS) and should be attached with the
port number of ITS Server (to get port number detailed description is given below). ex: hostname : port number
c)      ITS Path - To get the path along with the port number you have to Log on to R/3 system. Use the
Transaction Code "SICF", it opens a new window go to:
      default_host -> sap -> bc -> gui -> sap -> its -> webgui -> SAP GUI for HTML -> right click on
that and click "Test Service'. This will open a new window, on the address bar you will find the "port number", and
the path something like (/sap/bc/gui/sap/its/webgui). Use the path after the port number.
d)      ITS Protocol - There are two protocols "http" & "https", select the appropriate protocol which is
visible when you opened "Test Service" window.
12) Select "Web Application Server" property , now fill the required fields like
a)      Web AS Description -> Give some Description
b)      Web AS Host Name - same as ITS Host Name
c)      Web AS Path - usually /sap/bc/bsp/sapd)*
Web AS Protocol - should be same as the ITS Protocol.
13)   Select "User Management" property, now fill the required fields like
a)      Authentication Ticket Type - Since we are not using SSO leave the field
empty i.e. put in select mode. (Please note that longer term you will probably want to use SSO)
b)      Logon Method - Select UIDPW.
c)      User Mapping Type - In case you have administration rights then you choose "admin" or in case you
just have user rights then choose "user", better go for "admin/user".
14)   Since all the required fields are filled appropriately now create a System Alias name, this can be done by following steps:
a) go to Display -> Select "System Aliases" give some Alias Name, let's call it "SAP_R/3"
15) Now that System is created we have to create a iView which will display the given Transaction Code.
16) Go To "Content Administration".
17) Go To "Portal Content".
18) Go to Portal Content (Right Side Panel), open that folder
19) Right Click on Portal Content, a Panel is displayed select "New" -> iView
20) Select iView template, click next
21) Select "SAP Transaction iView" from the list of templates available. Click next.
22) Give the iView name and iView ID. Incase you want to give any brief notes about the iView then give it in "Description" field. Click next
23)   Select "SAP GUI for HTML" radio button. Click next
24) Now select the system which you have create "SAP_R/3", give some Transaction Code, say SE12 (Dictionary Display). Click next and Finish.
25) Now Preview the iView
26) You will see a new Window where in SE12 Dictionary Display window is displayed.

SAP Netweaver Portal Single Sign On.

Ok, I need some help!
We have a dashboard that is accessed through a SAP Netweaver Portal. The Dasboard gets it's data from a LiveOffice Crystal Reports object which when refreshed asks the user for the BOE logon credentials. The users do not want to have to Log in to the BOE for the Crystal Report to refresh, so the question is has anyone successfully managed to use some method of Single Sign On from SAP Netweaver to BOE (v3.1) for a dashboard SWF refresh?
Many thanks

Hi Charles,
can you share with us the configuration steps needed in the SAP Portal in order to use SSO?
Thank you.

Do a new layout on SAP NetWeaver Portal need more Performance?

Hello,
we want to create a new layout on SAP NetWeaver Portal in the Corporate Design of our company. Somebody said me, that a change from the standard layout needs a lot of more Performance on the server. Is that true?
At the present time our server already works very slowly with the standard layout. Is it useful to change the layout? Or do we need a better server for that?
Thanks in advance!
Best regards,
Ulrike Arndt

Hi,
It depend on how you design your layout.
Use standard light framework and design your layout without heavy weight components.
It increases the performance also.(a little b
it.)

SAP Netweaver Portal - Folder structure and report publishing strategy

Hi gurus,
I'm working on a project in which we are publishing BW reports in SAP Netweaver Portal (prior to this, we were using SAP Bex Browser) organizing it by Department (workset, 2nd lvl of navigation), Business Processes (workset, 3rd lvl of navigation) and "iview types" (transactions, queries, dashboards and so on). On 1st level we have a workset simply called "Reports".
For each PFCG role we have on BW (ABAP Server), we created a portal role and defined which of the higher navigation tiers is visible to users (delta-linking the top level navigation worksets to the portal role and setting visible accordingly) and then we assigned Portal roles to the appropriated Group (PFCG role) so all users that have access to certain PFCG role can have access to the corresponding Portal role.
For example:
In BW (ABAP) we have a PFCG Role: Sales PMR Analysis - Administrator, which grants access to Sales Infoproviders, queries and data for PMR analysis. The user that have access to it, should be able to see:
|Reports|
|Sales Administration|
v PMR Analysis
> Web Queries
> Transactions
> Dashboards
> Workbooks
In Portal we create a workset that has: "Reports" and under it, all Departments (Sales Administration, Financial, Services, Human Resources and so on) set as "not visible". We create a Portal role called PMR Analysis and add the Report/Departments workset, set Sales Administration as visible and add worksets/folders named PMR Analysis, Web queries, Transactions, etc, and all the corresponding iviews under it.
If we assign this new Portal role to the Group of the corresponding PFCG role, the user will see exactly as the example from above.
Pros: The users have a clean view of the reports he/she has access.
Cons: The users doesn't have a clear view of what is available in BW so he can request access. There might be some useful report lost in on of the hundreds of BW roles that he doesn't know it exist.
One of the options would be to grant visibility to ALL departments, business processes and iviews in Portal and let PFCG security roles control user access, but that might be confusing to have an overwhelming amount of links, making it hard to find what the user needs, specially during first access. Not to mention possible security breaches.
So, I'd like to know how other consultants are defining this kind of folder structure and report publishing strategy in Portal. Ideally we would like to be able to have:
- Visibility of all existant reports even those that the user does not have acess (so he can learn that it exist and request access)
- Clean view of reports, segmented by department and business processes.
- Possibility to search for reports, even for those that the user does not have access.
I'd appreciate if you guys can share your experience on this.
Thanks in advance.
Leandro

Cons: The users doesn't have a clear view of what is available in BW so he can request access. There might be some useful report lost in on of the hundreds of BW roles that he doesn't know it exist
This is not a refutation: your BW developers/consultants should be able to write reports, which points you in case of insufficent backend rights. EP is not designed to be familiar with ABAP security concept and cant take any influence at it.
One of the options would be to grant visibility to ALL departments, business processes and iviews in Portal and let PFCG security roles control user access, but that might be confusing to have an overwhelming amount of links, making it hard to find what the user needs, specially during first access.

Yes, bad idea.
- Visibility of all existant reports even those that the user does not have acess (so he can learn that it exist and request access)
As you already wrote on your own, this would be not good
- Clean view of reports, segmented by department and business processes.
- Possibility to search for reports, even for those that the user does not have access.
This is not covered by SAP, if you wanna provide that, develop it on your own.

SAP NetWeaver Portal Crystal Reports PDF Export Problem

Hallo all,
We are working with BO Edge XI 3.1 with integration on SAP Netweaver Portal. The problem is that integrated in SAP Portal CR reports cannot be exported to PDF or printed out.
I am using an URL iview with the parameter sOutputFormat=P to run the report.
When I want to print out the report I get the warning message from Internet Explorer "The download of files from this page is for security reasons blocked. Click here..." --> Download the file. By clicking on the u201CDownload this fileu201D the report starts to run again. PDF export doesnu2019t happen.
Did somebody have the same problem?
Thanks a lot in advance!

Hello Ingo,
thanks a lot for Your help. I have already talked to my IT department and they are looking for the solution of this problem, too.
Is there a documentation about necessary settings in the browser to work with SAP NetWeaver Portal and Crystal reports?
The problem is that on some clients the PDF export is working and on another clients not. The settings of IE seem to be equal.

Katharina

SAP NetWeaver Portal on HP-Hardware - Experience?

Hi @All,
we are using an SAP NetWeaver Portal on HPUX PA 11.11 but the response time is very long even with 8 CPU and a lot of RAM.
In the past I've made good experiences with Linux on AMD with 64 bit but this woud be a real big change us.
Somebody used itellium CPU's?
From my point of view we have these options:
-> HP UX PA 11.11
-> HP UX IA
-> Linux AMD
I'm interessted in the performance of the different solutions.
Thanks a lot in advance.
Best regards,
Michael

Hi James,
yes for sure.
But in fact: HPUX on PA is much slower than Linux on AMD running the same portal.
So the question is what do use for the future:
HPUX PA
HPUX IA
Linux AMD
Best regards,
Michael

SAP NetWeaver Portal on Cloud + customizing

Hello,
if we use SAP NetWeaver Portal on Cloud how wide is the possibility to customize it?
a) will support packages installed automatically?
b) can we customize the portal on cloud with the same possibilities as portal non proemise?
c) how can we integrate iviews from apllications, whiche are not on cloud?
d) how can portal on cloud uintegrade in the cts+ , which is not on cloud?

As explained in another thread of yours, there is no such thing as "SAP NetWeaver Portal on Cloud" and if your questions are about SAP HANA Cloud Portal, please post them in the corresponding space: SAP HANA Cloud Portal.

SAP Business One in SAP NetWeaver Portal?

Hi,
We have a customer that will implement SAP Business One for their backoffice.
They want a package solution for their internet and extranet (clients and suppliers). The extranet will access SAP Business One.
We are considering to implement SAP NetWeaver Portal for the extranet.
Do you think this is possible? What about SSO?
Tahnk you all,
Olivier Marques.

Olivier,
I am not sure about the SAP NetWeaver Portal. You may want to ask that question in the NetWeaver Discussion Forum.
With respect to the SAP Business One Integration for SAP NetWeaver product ... this technology is not providing a portal in which to access SAP Business One from a web interface. The SAP Business One Integration for SAP NetWeaver is a technology that seamlessly integrates SAP Business One with mySAP with respect to the integration of transactions and master data flow between the two systems from a headquarters/subsidiary(s) standpoint.

How to enable change password feature in SAP Netweaver Portal 7?

Hi experts,
I would like to provide a change password link just beside the logout link after user had successfully logged in to Sap Netweaver portal. When user clicks that link, a change password screen sill appear to allow user to change his/her password.
Question:
1) How do i create a link in portal header just beside the logout link?
2) Is there any default change password page for Sap Netweaver Portal that I can use for this purpose?
Thanks,
Kenneth

Hi,
To get the change password link beside logout, get the masthead PAR file from portal, import into your NWDS, make the changes in the JSP and upload PAR file back to portal. Search with keyword "Masthead customization" in SDN. You will get many documents to achieve.
SAP has password change functionality available. Chekc the link below for details.

Downloading SAP NetWeaver Portal

I was wondering if I could get some help in downloading the trail version of SAP NetWeaver Portal 7.1.
I downloaded SAP NetWeaver 7.01 ABAP Trial Version. I am installing the SAP NetWeaver 7.01 ABAP Trial Part 1. But it seems that this package does not include the Net Weaver Portal. How do I get the portal installed? Did I get the right package of NetWeaver? My project has to do with Content Management and I was interested in the Knowledge Management component of Net Weaver Portal.
Please help me guide through the process. Thanking you in advance.

Yes, it supports creating and editting documents through a simple approval/workflow mechanism.
Through WebDAV it can be used from Office.
It doesn't do document conversion.
Try the SAP Help pages http://help.sap.com for NetWeaver and there you will see KM...
