ESA using SAP XI

Hi All-
There have been quite a few posting in this forum regarding the role of Exchange Infrastructure in achieving ESA.
XI acting as an integrator of the buisness processes; which actually inturn would aggregate to an organisation achieving the SOA.
I am not very sure on this; but according to my understanding, a lot would depend on the way the systems are potrayed in SAP XI System Landscape. More specifically the way the SLD(Software Component) is being laid out not just for the SAP but also for non SAP components with in an organisation.
My question is :- Are there any generic guidelines which can be followed for defining the Software Components within the SLD.
One of the methods that we are following is to arrange the Software Components and the Products for the Third Party components on the basis of products and software component which are being identified in that particular software product.
But, what would happen in case there are a lot of File to File interfaces. In such a case there won't be any specific product that we would be talking about and in that case may be arranging them using Business Processes may help.
Please provide your feedback.

Hi Ashish,
I guess you have nailed down both the ways of defining the systems in the SLD of XI. Choosing one of them, I would guess will changes from landscape to landscape. However, I am inclined to say that defining a landscape from a business process perspective would make lot more sense (irrespective of systems being defined) as ESA is all about business processes and not about the technical systems.
In my view, as XI is going to be the central component, the SLD should be defined and maintained in XI and all the other systems in the landscape should be pointing to the SLD of XI.

Using SAP PI instead of CRM Middleware

Hi experts,
Is it recommend to use SAP PI instead of SAP CRM Middleware.
If yes how can I do that.
I have read in forum requests that it can be implemented by using iDOC instead of BDocs.
I need a technical guideline how data (eg. Business Partner Data) can be tranferred from CRM to other ERP System.
Thank you for help.
Greetings

Hi!
SAP PI itself is a middleware Product but very roboust and capable enough to integrate any system to any other system, either it is SAP or Non-SAP. And there are two ways to integrate other ERP System to SAP CRM using SAP PI.
1. SAP PI will receive the message from back end ERP system & convert it to the XML format. SAP CRM receives the message using the Middleware XIF adaptor and convert the incoming XML Messages in the BDocs and the BDocs upload the data in the SAP-CRM Data base.
2. SAP PI will receive the message from back end ERP system & convert it to the XML format. SAP CRM receives the message and using the Functional Module convert the data into the BDocs and the BDocs upload the data in the SAPCRM Data base. In thsi situation, you need an expert ABAP Consultant to write the accurate functional Module.
The data inside the SAP_CRM System always transported in the BDocs not in Idocs. It is the BDocs data containers which transport the data from CRM Middleware to CRM Database and CRM Database upto CRM Middleware.

SSO Using SAP GUI Logon

Here's my question gurus...
Is there a way to enable SSO so that, after a user authenticates themselves within the portal, go back to the standard Windows SAP GUI Logon(pad) select the system enter the desired client and logon with having to provide a username and password? The credentials would be passed from the portal to the connected backend system.
We currently have a slew of systems and there corresponding clients it would be awesome to sync all systems with the portal and only have to administer passwords from and for the portal. Consequently the portal would handle the rest. The folks here have not fully embraced using the html version of the gui hence the reason for this posting.

Hi Mike,
If i understood your requirement, You want to use SAP functionality form portal.
You Can do that, by creating a SAP System from your portal and you can call any Transactions from the portal it self, by using that System.
How to create System and User mapping for that System you can find in the below link. It may helpful to you. Ping me back, if you have any doubts.

SSO to non SAP Application using SAP Logon Ticket

Hi Experts,
I Have EP 7 SP 15 using SPNego Wizard to SSO with Active Directory and SSO between EP and ECC using SAP Certificates.
Now I have a demand to SSO some JAVA based applications (non SAP) to my portal using the SAP Logon Ticket.
I Have followed some blogs that directed me to use SAPSSOEXT (some libs) to read the MYSAPSSO2 cookie. The problem is that I didn't found this cookie, I even executed the command javascript:document to look for this cookie but the browser just show me the JSESSIONID info.
Does anybody knows where I can find this cookie or if there's a better way to set up this SSO? It´s necessary to say that I cannot SSO these application to the kerberos protocol because some security reasons on my company.
Thanks
Armando

Hi,
I dont have much info related but i can giv u hint
refer OSS Notes 442401 and 723896.
When using SAP logon tickets for non-SAP applications, two different implementation options are available. The difference lies in where the ticket verification takes place.
In the first case, the SAP logon ticket is submitted to the web server filter located on the web server. The web server filter verifies the portal serveru2019s public key
certificate using its local Personal Security Environment (PSE) and then populates the HTTP header field with the user ID for SSO to the non-sap web application.
In the second case, the SAP logon ticket is sent to the non-SAP application, which then verifies it using the ticket verification DLL and submits the user ID to the application for SSO.

How to implement SSO to non-SAP systems using SAP logon ticket?

Hello,
We would like to implement Single Sign On between our SAP Netweaver system and a Siebel which is a non-SAP system using SAP logon tickets.
Can anyone please give me some leads on this, in particular:
1. Is there a JAVA API or an SAP plug-in that can be implemented on the Siebel machine to extract the SAP logon ticket?
2. As the other machine might seat on a complete different domain, is it possible to implement SAP logon ticket without using cookies (perhaps through the HTTP header?
3. In case you think using SAP logon tickets is not the best solution here I would be happy to hear any other suggestions you might have.

Hi,
I'm currently using SAML as well. Unfortunately the SAP J2EE cannot work as authority (identity provider) but what you can do is using an open implementation of SAML such as opensso which is an open version of SUNs Java System access manager.
There are a couple of other projects such as opensaml, apache's wss4j or shibboleth that might be interesting in this context.
I just installed opensso and got it working with SAP J2EE 7.0 using SAPs JAAS SAMLLoginModule to authenticate users within SAP J2EE.
In this scenario opensso serves as identity provider just as you need! There are a couple of Policy agents available on SUNs Download site you can use with Apache, Tomcat, JBOSS, WebSphere, Bea Web Logic etc. in order to authenticate! Otherwise you just directly authenticate against opensso. When installing opensso you can configure the type of user store you want to use! By default it uses LDAP but you can also use different types of user store using JDBC or other mechanisms. Since you have a Directory Service you could easily connect it to your existing directory.
There is also a way to map user ids directly in opensso by adding a uid mapping class. I created some documentation with lots of screenshots about using opensso with SAP J2EE. You can easily use opensso with any other system that supports SAML. In the case of SAP the usage is currently limited to SAML versions 1.0 and 1.1. Version 2.0 is not yet supported but should be in one of the following versions.
Here are some links you might want to check:
OpenSAML: https://spaces.internet2.edu/display/OpenSAML/Home
wss4j: http://ws.apache.org/wss4j/
shibboleth: http://shibboleth.internet2.edu/
opensso: https://opensso.dev.java.net/
On SDN you will find a documentation on how to connect SUN Java System Access Manager to SAP J2EE (see https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/906d9fc6-31b9-2910-1385-90edad7d7570). As I said opensso is based on the SUN Access Manager code and looks quite the same. So you can adapt this documentation in order to configure opensso or you can just ask me for the documentation.
Hope this is helpful...
Let me know if you need further assistance on this topic
Cheers

SSO to Web Service using SAP Logon Ticket

Hi,
I have to do SSO using SAP Logon Ticket between my portal and a Java Web Service that is accessible over internet. I do have the WSDL file of this Web Service.
I want to know:
1. What changes are required in Web Service to configure it to read and accept Logon Ticket?
2. What am I supposed to do at portal end to enable this process?
Thanks,
Vivek

Hi Vivek & Raja,
> is it that if the WS is a third party WS and running on a Non-SAP J2EE Server,
> we can't implement SSO from Portal to it using SAP Logon Ticket?
Right, if you cannot extend it's functionality, how should it do the ticket verification...
@Raja:
> SAP Logon Ticket is for authenticating to a SAP system, since yours in a
> thirdparty ws, there is not need of SAP logonticket.
On the other hand, that's not true. It is possible as well as often done to verify the SSO ticket on some third party system. This is also supported, for Java as well as for other systems, different articles about such scenarios have been published, also here on SDN.
Hope it helps
Detlev
PS: Vivek, please consider rewarding points for helpful answers on SDN. Thanks in advance!

Display data vertically using sap script

Hi Developers,
Is there any way to display data vertically in a form using sap script?
thanx in advance,

Hi Binu,
It is not possible to rotate text in SAPscript. The usual work-around, provided this is static text and not from a variable, is to scan an image of the text and include it as a graphic.

What is the difference in Webintelligence while using SAP BW or MS SQL Server

Hi Experts,
What is main difference in using SAP BW and MS SQL server in SAP BO while creating Reports using Web intelligence, Crystal reports. I want to know mostly on Report Level difference.

Hi,
I Have not used Crystal with Ms SQL server but webI i can tell .
SAP BW is OLAP Layer .
M S SQL Server is Database .
You can Edit your Web Intelligence Query SQL Code in MS SQL Server .
Not in SAP BW .
Combined Query is Disable in SAP BW but it is available in SQL Server .
Performance wise SAP BW Query is better because it calculates every thing in SAP BW & gives us Required Out .

Pros & Cons of Using SAP PI Interfaces for Report Generation

Hi Guru's
I have a Scenario's like
I have to generate a customized report in SAP with the main data's available in SAP ECC and some required data available in the Legacy System.
I want to know the Pros & cons of using SAP PI RFC/Proxy adapter interface to get the data from the legacy system for each time the user execute the report in SAP ECC.
Thanks in Advance

There are couple of "dimensions" to consider in your PI interface design. For exemple when you are running the sizing exercise (Since we are considering adding a net new interface), you will need to capture specific information about new interface.i.e. S/A, adapters, frequency, avg payload size. etc..Note that the last two attributes will be hard to size properly in this case since you can't predict how frequent the end user will run the report which will impact the latency time required to pull the data. Latency will affect the user experience as visible side affect and definitely the SLA for other interfaces running at the same time.
On the other hand, the data you are trying to retrieve from the legacy won't be used for transactional purpose but for the end user to pull KPIs from the system which can affect ECC as well. You may end up doing lot hot fixes for your report (Assuming that the report is a medium complexity code)
There are other factors to consider but let's consider these are the major one.
Cheers,
