How to connect to a non-sap system in HCI?

Dear experts,
My scenario is to replicate the customer information to SAP Cloud for Customer from a non-sap system. The non-sap system is in the internet and it can be accessed by any system.
Now my questions is: The customer information flowed from the non-sap system is in a very specific format, should we develop a webservice for the customer information in HCI? If so, how to create new webservice in HCI? Does SAP allow user to create customized webservice in HCI?
BR,
Kurt

Hello Kurt,
HCI is available as a platform as part of the HANA Cloud Platform edition. With the platform edition you can develop your own interfaces within HCI. HCI has SOAP, FTP, IDOC and a succesfactors adapter which you can make use of.
It is possible to import webservice definitions and create the custom interface with your own mapping.
Best regards,
Fons

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

How to transport ALEAUD to non-SAP system?

Hello,
I have R/3 system which receives documents from non-SAP system. I want to transport acknowledgements from R/3 back to non-SAP system. I want to use standard SAP ALE monitoring possibility. All needed information exists in ALEAUD IDOC which can be generated by program RBDSTATE.
But I can not process ALEAUD IDOC in SAP XI because it always automatically converts to internal XI acknowledgement.

Can PPDS be linked to non sap system which records production

Hi, We are currently planning with SNP and PPDS but for part of our business, the manufacturing execution occurs in a non sap black screen archaic system. Is there any way to consume PPDS planned orders with the data from an external Production recording system? Or is the only way to consume PPDS planned orders via using SAP R3/ECC?
I have dug through the MES PDF and the BAPIs and cant find a way to "consume" the PPDS planned orders without using SAP R3.
Thanks
j

Hi Lokesh,
There is no limitation to connect two non SAP Systems,PI will support to connect two differt non SAP Systems.
The reuirement you mentiioned bit not clear,what i understood is use JDBC Adapter at sender side and SOAP adapter at receiver side.How to use these adapters search in sdn you will find tons of documents.

Regarding the Service Registry in SAP PI 7.1 and non SAP System ....!

Hi All ,
I need to know answers for the below Question ...hope to get some answers frm Experts ....
1) How to publish service from non-SAP systems?
2) How to use discovered service in the Service Registry for consumer/provider scenario? With some examples.
Thanks in Advace ...!
Regards ,
Aziz khan .

Hi,
1) How to publish service from non-SAP systems?
Publish Service is nothing but making WSDL of that service available. For that you need to Publish the WSDL of the web Service to UDDI. For Non SAP system, Lik .net , Java they have there oun APIs to do so. U can search on net to get it.
For Ex. below link.
http://www.startvbdotnet.com/web/publish.aspx
2) How to use discovered service in the Service Registry for consumer/provider scenario? With some examples.
Once you discover the services, you get the WSDL of that Service. Then You can import this WSDL in IR and you it.
See the below links.

Want to access non SAP system from EP

Hey Guys,
We are having a system (CRMS) which is a non SAP system. I know through EP we can connect to the non SAP system.
Can somebody pls tell me the steps to do this. I want to access the data from non SAP system on Enterprise Portal.
Pls provide me the useful links / doc.
Thanks in advance.
NIkesh Shah

Hello Nikesh,
As I mentioned, kindly check up on help.sap.com.
Anyways:
Create an HTTP system using the System Templates Provided. Instead of selecting SAP Systems you select HTTP system. Provide parameters:
Authentication method: POST
Authentication Type: Server
URL Parameter for Password & URL Parameter for Username: This you can get by doing a View Source on the Login Page of your CRMS appln. e.g. <input type = "hidden" name ="user"> -> So in this case you pick up user
In User management property select Usermapping and admin,user
Now create a URL iView:
System: Select the 1 you created.
URL: URL to your application till before any query string starts.
REQUEST Methid: GET
URL Parameter 1: <the user param from the source> TYPE = Mapped User
URL Parameter 2: <the pwd param from the source> TYPE = Mapped Password
Enter the user mapping for that user and test the iview.

Connect b/w SAP and Non SAP -system

Hi All,
I have a requirement where i need to connect between a SAP system and Non-Sap System.
the front end is an E-Build tool (for construction Industry) from where the user will pick the data and the data should get store at the backend i.e in the SAP system.
E-build is a tool for construction industry with lots of flexible options for the user to check for their house, along with their prices.
These all data needs to be captured and store at the backend.
Can any one suggest me which method shall i go for this in ABAP(and How) or need to go for the XI-Netweaver or EP technology.
Thanks & Regards
Mona

you better to go for middleware tools . keep files( whichs contains data to be stored in SAP) in one folder at 3p systems and middleware adapters will pick that filles automatically and sent it to Application server or then process the data into SAP.
tks.. venkat

Integrate or connect SAP system to non-SAP system

Hi All,
We need to connect SAP system or integrate inspHire rental software to SAP. Do you know the process or initial summary on how to integrate this one?
As of now, the only way that we know to integrate SAP to non-SAP for posting is thru LSMW and batch input.
your suggestions will be greatly appreciated.

Hi,
LSMW is just tools for integration and you can use BDC Call Transaction, BDC session or BAPI, or Function to update something ins SAP.
1/Easier is if your non-SAP system is able to create file and ftp to SAP folder.
2/You will have background job running program that will every 5minutes or hour or daily(it is up to you how fast dat has to be bring to SAP) check if file was create in SAP folder.
3/Program will move file to folder in process
4/Program will process file, usinf function, or call transaction to update SAP on the base of file
5/Program will move file to process folder
If you need more info give me detail about what you would like to update in SAP and I could send you code.

Hi Dharani,
You can get information from the following links:
http://help.sap.com/saphelp_nw04s/helpdata/en/43/d08b00d73001b4e10000000a11466f/frameset.htm

SAP CONNECTORS:- Basically Connectors are like middlewares , that we use to connect to the backend system including Non SAP systems also. Will try to explain it to u with some examples of SAP Connectors:-
a) SAP Business Connectors:-
A middleware application based on the B2B integration server from webMethods.
The SAP Business Connector enables both bi-directional synchronous communication and asynchronous communication between SAP applications and SAP and non-SAP applications.
The SAP Business Connector makes all SAP functions that are available via BAPIs or IDocs accessible to business partners over the Internet as an XML-based service.
The SAP Business Connector uses the Internet as a communication platform and XML or HTML as the data format. It integrates non-SAP products by using an open, non-proprietary technology.
b) SAP Java Connector:-
SAP Java Connector (SAP JCo) is a middleware component that enables the development of SAP-compatible components and applications in Java. SAP JCo supports communication with the SAP Server in both directions: inbound calls (Java calls ABAP) and outbound calls (ABAP calls Java).
SAP JCo can be implemented with Desktop applications and with Web server applications.
SAP JCo is used as an integrated component in the following applications:
1) SAP Business Connector, for communication with external Java applications
2) SAP Web Application Server, for connecting the integrated J2EE server with the ABAP environment.
SAP JCo can also be implemented as a standalone component, for example to establish communication with the SAP system for individual online (web) applications.
To Know more go through,
SAP Java Connectors
II) ALE Concept:-
ALE is not restricted to communication between SAP systems, it can also be used for connecting SAP Systems to non-SAP systems.
By using IDocs as universal information containers, ALE can reduce the number of different application interfaces to one single interface that can either send IDocs from an SAP system or receive IDocs in an SAP system.
SAP certified Translator Programs can convert IDoc structures into customer-defined structures.
Alternatively, the RFC interface for sending and receiving IDocs can be used in non-SAP systems.
In both cases you need the RFC Library of the RFC Software Development Kit (RFC-SDK).
This link gives a great insight into landscape for Connectivity to Non-SAP systems:-
SAP to Non-SAP systems
III) Communication Between SAP Systems and External (Non-SAP) Systems using RFC:-
When you use RFC for communication with an external (non-SAP) system, you can also implement the SAP Java Connector or the SAP .Net Connector for the conversion of data. However, there are no specific security requirements for these components, since they only perform internal system conversion functions.
The additional security recommendations for communication with external systems in this section make particular reference to cases where an external system is used as a server (SAP calls the external system). If you use an external system as a client (the external system calls SAP), the appropriate SAP-specific security mechanisms are implemented on the SAP side.
This link explains in detail all the security considerations you need to take for connecting to an External Non SAP system like, User administration, Network Security etc.

How to extract data from ODS to non-SAP system

Hi,
Can anybody tell me, step by step, how to extract data from ODS to a non-SAP system?
Is it possible to do it without programming effort? And is there volume limits for this kind of extraction?
The non-SAP system is an unix system.
Thanks in advance
Ella

Ella,
You can look at it from the concept of a BADI / Infospoke
Extract the data from the ODS to a Flat file / RDBMS using an infospoke. I am not sure as to how the infospoke loads data into the RDBMS ( did it very long ago ) but then you can push it into an RDBMS and I am sure it will be system neutral.
Hope this helps...
