ABAP Web Services for RFC

Hello there,
We are trying to provide a web service in our organization to an external vendor to access our CRM Systems to get some information. The business functionality is enclosed in a RFC. Now i need to provide it as a web Service. I would like to know the answers for the following,
1. How do i create a provide Web Service? (If there is any step by step guide, it will be ideal).
2. What information does the external vendor need to access my web Services?
3. What is the general security constraints we need to look into?
We are in NW 7.0 with CRM 5.2.
Thanks in advance............

Requirements for the development of ABAP web services...

Recently at TechEd in Vienna I saw a demo of the development of an ABAP service. It all looked fairly easy, so when I came back I decided to try it out for myself. However, this mission seems to be compromised by the development environment not playing along. I've tried to encapsulate a small RFC function module inside af service on an IDES ECC 6.0 system and that went fairly well until I wanted to test the service.
At some point it is understood that one should setup a reference to a J2EE system in the WSADMIN transaction and that caused me some troubles as it looks like the IDES system that I tried it on doesn't have a java stack. How could I check whether that is true? I then tried to test the service directly under maintain service within WSADMIN and it sends me a popup screen and asks me to logon. After logging on the browser claims an internal error has happened.
What do I do now? Where do I start to check if everything is setup the way it should be? Is there a note or a how to guide somewhere?
Best regards,
Anders

Hello,
For creating and hosting ABAP web Services, you do not need JAVA stack. However, for testing Web Services using Web Service Navigator (from SOAMANAGER), you need J2EE stack.
If you are invoking Web Service from SOAPUI, .NET or some other third party tool, you need to create End Point for the service using SOAMANAGER and provide the Porttype WSDL to the third party system.

RFC works but web service for that RFC does not work..weird??

hi all,
I created an RFC enabled function module to create a Sales Order in SAP CRM for both for Varinat Configurable and Normal Materials.
The RFC Works well...if i test it..it creates an order and if i go and check the sales order in CRM GUI. i find that sales order is perfect with the configuration data for the configurable items..
Now i created a Web service for this RFC by calling the Web service creation wizard.
Now i am testing the Web service in SOAMANGER T-code and the sales order is created and weird thing the configuration data is missing for Varinat configurable item..
But i dont encounter this problem if i am testing the RFC directly
What could be wrong...why is my web service behaving weird?
I am dying to find this out..did any body enocunter this situation befor ..please help

Sure Oliver..
I put a break point using external debugger and when i was testing the Web service in SOAMANAGER..
i could then land into ABAP debugger.
There in my RFC i put a logic such that i diffenetiate between VC and Non-VC items and fill the Charateristic Values only if it is aVC item.
I saw that the IF condition was not executing as they suddenly changed the material structure in ECC and it reflected in CRM.
SO i am inputting 18 digits of material no like '000000000000000001' for '1'...but the if condition was checking against 1 =1 so that loop never executed and chara values are not getting filled.
But if i test RFC in se37 ..it works as i am inputting 1...
Since Web service works with XML (WSDL) need to be very careful with the format in which data is inputted and the format in which the logic we wrote in RFC works.
Once again ..thanks to all people who helped me with the answers...

Jessica Sam

Issue in creating web service for a ABAP Function Module

Hi,
now i'm learning how to create web service for a ABAP Function Module. I used the following steps.
1. select the Function Module, named "zws_test".
2. in the context menu, select "create->proxy object". so we enter into wizard.
3. in the wizard, press the radio button "Service Provider".
4. in the next page, press the radio button "Existing ABAP Objects(Inside Out)".
5. In the next page, Enter the "zws_test_prvider" as Service Definition and select "Function Module" as Endpoint Type.
6. in the next page, enter "zws_test" as Function Module and mark the "Mapping der Namen" button
7. in the next page,select "PRF_DT_IF_SEC_LOW" as Profile and mark "Deploy Service".
8. Save in the local package.
9. then it will pop up a window with title "WSDL Source". i selected "URL/HTTP Destination" and press "OK".
10.in the next page, i enter the URL as "http://hostname:portnumber/", and press "OK".
11. then it will pop up a window with title "Display logs". A record with error message "HTTP error(return code 404, message "Not found")" appears.
12. i press "ok" and a service provider with name "zws_test_prvider" appears in my local package.
13. i use "zws_test_prvider"'s URL to create a service consumer "ZCO_WS_TEST_CONSUMER" and logic portal "LP1".
14. But when i test my service consumer "ZCO_WS_TEST_CONSUMER", it will throw an exception "cx_ai_system_fault" with errortext "SOAP:14 Unexpected element -el=definitions ns=http://schemas.xmlsoap.org/wsdl/".
15. I use t-code SM59 to test connection and get the following info.
      Status HTTP Response     200
      Status Text                      OK
      Duration Test Call             328 ms.
who can give me the reasons about item 11 and 14, and explain me how to create service provider and service consumer for a Function Module.
Thanks in advance

Web services enabled RFC for SO creation in SAP 5.0 is not responding

Dear Members,
Third party application is not able to getting response from SAP R/3 web service enabled RFC.
We have created a RFC for creation of Sales order by passing mandatory values into SAP thorugh third party application from outside SAP. Accessing RFC in SAP through Web service is not sending response properly. However Sales Order is getting created in the SAP system perfactly, in return to third party application to out side SAP through web service throughing an Exception.
As standalone RFC in SAP, which is creating Sales order perfactly.
Here we have deleted web service of RFC many times and recreated also, still the problem is not get resolved.
Web services is got configured perfactly in the SAP, because other RFCs are working fine.
Please someone suggest how to resolve this issue in case of Sales Order creation through web service enabled.
Sudheer

Hi ARC,
Here the issue is that, Sales Order is getting created but while sending the Order num. to Webpage through web service then rasing below Exception.
Runtime Error UNCAUGHT_EXCEPTION
Except. CX_SOAP_CORE
Date and Time 07.05.2008 20:13:24
ShrtText
An exception that could not be caught occurred.
What happened?
The exception 'CX_SOAP_CORE' was raised but was not caught at any stage in the
call hierarchy.
Since exceptions represent error situations, and since the system could
not react adequately to this error, the current program,
'CL_SOAP_TRANSPORT_EXTENSN_ROOTCP', had to
be terminated

Authorizations for testing of ABAP Web Services

Can somebody tell me which authorizations/roles I need to assign to a user with SAP WAS 6.40 ABAP so that he will be able to test a simple ABAP Web Service with the Java Service home page of this service?
I tried this with the roles SAP_BC_DWB_ABAPDEVELOPER and SAP_BC_WEBSERVICE_ADMIN but this seams not to be enough and I could not find a hint on how I could find out what is going wrong.
The user gets an error message on the top of the service home page when he submitted the service request:
"An error has occurred. Maybe the request is not accepted by the server:
Authority check failed"
The service is configured with standard authentication. On the service test page the user gets a login screen which he passes successfully. The error occurs afterwards when the services test is executed.
Many thanks!
Best regards, Birgit

Hi,
1. log on to SAP system with user XXX .
2. Do your steps to call webservice from JAVA Service home page - use the same user id for log on.
3. As soon as you see the error message as you mentioned
Run transaction SU53 in the target SAP system . This should tell you the authority object where the failure had happend.
Hope this helps.

Web Service Model for ABAP Web Service

Hi,
I have developed ABAP web service and called it using web service model in WD. The WS is working from WSNavigator. While calling it from WD, im getting the following exception:
Service call exception; nested exception is:
com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (502) Proxy Error ( No data record is available ).
Is some setting required in R/3 where WS is created or on WAS where the WDAppl is deployed?
Regards,
Smruti

Hi Smruti,
Please try the following:
Go to Web Service model
Logical Port
Uncheck "Use HTTP Proxy" settings..
Also make sure the WAS has entry of R/3 in hosts files..

Thanks Venu for your input.
Unfortunetly we do not have Java stack on our development system. You said we can test it by SOAP UI tool. Where do I see the WSDL file for the service?
I used WSDL from SE80 --> Service --> WSDL tab, but SOAP UI does not accept this format ?
What are the other ways I can test this web service? I think about SAP PI, importing RFC & creating web service or creating ABAP proxies... Which is the best way to go forward in case you do not have Java stck.

Consuming ABAP Web Service in Non SAP system

Hi
I have created an ABAP web service form the RFC and configured it in the SOAMANAGER. I have tested it in Web Service Navigator using the URL and it is working fine.
Now I am trying to access it from the Non SAP system using Java Code. I am able to access the WSDL using the URL from the step 1 but not able to receive any output when providing inputs.
So I am not sure if I am missing any configuration on the Provider System (SAP) or on the Consumer system (Non SAP) to access the web service. As far I have not configured anything on the consumer system. Please let me know how to consume the web service in the Non SAP system.
Thank you,
Rohit

not necessarily an answer to your question, but i find that when creating SAP web services, before we create the code for consuming them, I always test them with the SOAPUI package. with this test suite you can import the WSDL, and run individual tests, seeing the input, output, exceptions, etc. This is a good way to check the connection, the flow and the service logic, before writing any code. This will also let you know whether it is a WS issue, or an issue with your code.
just a thought, from someone who has been there...
http://www.soapui.org is where you can find the SOAPUI. It helped me out a lot.

Problem with ABAP Web service

Hello Experts,
Some unusual thing is happening.
Till this time my scenario was HTTP to RFC. So i have imported RFC in XI and its structure was perfact.
Tables having cardinality as 1...1, and fields were having cardinalities as 0....1.
Now we have planned to switch to the proxies and ABAP Web services. I have created the ABAP Web service with the same function module and imported it into the External definations.
When i am trying to use it into the mapping, Table cardinalities are 1....1 and fields are also having cardinalities as 1...1.
Now because of that i hv to map all the fields with some constants, but m not comfortable with it as there are nearly 1000 fields.
Do anyone of you have any idea what might be the problem? or how can i solve it.
Hope the question is clear.
Please help in this problem.
Thanks,
Hetal

Hello Hetal,
This is happening because when you genarte the Webservice out of a Function Module, all the fields in your are mendatory in the generated WSDL.
This can be avoided. The WSDL that you have generated for your webservice, can be manually edited in Stylus studio etc to change the cardinality and make it optional. We also did the same in one of our scenario and it is working fine.
As you are mapping these fields with constants, so it doen't make a difference if those are optional too.
Just edit the WSDL/xsd and reimport it.
Thanks

ABAP Web Service with tables

Hello,
 
 
We need to build a web service with a predefined message in our ERP (ABAP), without PI or WebAS JAVA.
 
 
We thought it should be a simple task, because we had no problem with many other applications and systems when building the same service, but were not able to build it with SAP ABAP, probably as a consequence of our lack of knowledge on ABAP SOAP runtime.
 
 
We have an external asynchronous process that delivers information to many other systems using web services (information diffusion). Concecuently, the web service call's structure is determined by the caller, so we have to fulfill this structure if we want to receive the info.
 
 
The owner of the process defined a very simple service call, in which one kind of "record" can be repeated 1 to n times:
 
 
 
 
 
 
<reglasSuscripcion>
 
 <!Zero or more repetitions:>
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
</reglasSuscripcion>
 
 
 
In order to receive this info, we have to implement an abap web service handler to accept this kind of call, the same way other applications/systems have already done.
 
 
We tried to build a RFC function call and create a web service with the wizard and it resulted in a web service with the following WSDL:
 
 
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:sap-com:document:sap:soap:functions:mc-style">
 
 
 
 
 <reglasSuscripcion>
 
 <!Zero or more repetitions:>
 
 <item>
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
 </item>
 
 
 
 
<item>
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
 </item>
 
 </reglasSuscripcion>
 
 
 
 
We found two main problems:
 
 
1.- When "wrapping" the RFC as a WS with the wizard, for a table datatype it automatically includes the <item></item> tag, so we break the predefined calling rules.
 
 
2.- The namespace is fixed by the wizard, and we would like to use a common namespace for all the "susbscribers", logically, the namespace fixed by the information diffusion service.
 
 
We also tried to find info on the outside-in approach for building a web service from the WSDL, but all the info we found required the ESR and we have no PI, just the ERP.
 
 
Any ideas on how to proceed?
 
 
Thanks in advance,

#2. I've recently had to "zap" some namespaces in an ECC5 system because the calling (TIBCO) system didn't appreciate the default SAP "urn" default - something to do with multiple colons in the address. There were, I think, just three table this affected, all VEP* ones. I think I should have been able to change these via the virtual interface in SE80 except that the ECC5 code was a bit "light" in this respect, so you may be able to do this now in SOAMANAGER in ECC6 (btw, I also had to re-save the WS definition within WSCONFIG and re-activate the virtual interfaces after this "zap" to generated the associated handler class again).
#1. Given your "name / value" pairs represent a complex type, then it might be better practice to have them as "item" which is probably why SAP proposes it this way... what does your custom function module parameter list look like?

Calling an Abap Web Service from IBM WebSphere with a MYSAPSSO2 Cookie

Hello,
I have the following problem :
I have to develop a proof of concept between IBM Web Sphere 5.1 and SAP AS JAVA 7.0.
I have created an IBM sevlet in Web Sphere, I use a specific redirect from an SAP AS Java to call it, this way I can have a SAP Logon Ticket, and I manage to call an ABAP module function with JCO with SSO.
Scenario 1 : browser + authentication --> AS Java redirect servlet MYSAPSSO2 cookie -> IBM WebSphere servlet JCO -> Abap module function (ECC5)
This scenario works fine.
I have to do the same scenario with a Web Service and I don't know what to do.
I try to use jax-rpc handlers but I don't know how to pass my cookie from my servlet to my handler.
Scenario 2 : browser + authentication --> AS Java redirect servlet MYSAPSSO2 cookie -> IBM WebSphere servlet JCO -> Abap Web Service (ECC5)
Has someone already done that ?
Regards, Julien.

Julien,
Why are you using 5.1....go for 6.0 and its cake walk, i have integrated WebSphere 6.0 with R/3 uysing xi.....in a week.
Scenario changed to:--
Browser+ authentication --> WebSphere AS servlet request --> XI --> RFC/bapi --> abap webService
Hope that helps

Using ABAP Web Service tor convert IDoc to XML and transfer to SOAP Server

Hi all,
I have a problem to use ABAP Web Service to convert IDoc's to XML and then send them to a SOAP Server.
Currently we have the following landscape:
SAP->XI->Archive
The sap-system (ECC6.0) sends an IDoc to the Exchange Infrastructe. The XI maps the IDoc and converts it to the required XML format, used by the archive. Afterwards, the XML documents are sended to the SOAP Server.
So I'm trying to replace the Exchange Infrastructure with ABAP Web Service.
I've read a lot of posts and documents reagarding ABAP Web Serivce, converting IDoc's to XML, RFC and so on, but I'm not able to do the replacement.
I don't know how to start and which steps are required.
The required roles and authorizations at the sap-system and the service for soamanager and the Web Service Viewer are available.
First I thought to create the RFC and partner profiles and then the report to convert IDoc to XML as a BAPI. With this BAPI I supposed to create and define a Web Service. The problem is, I don't know how to trigger the report if the Idoc should be send to the archive.
Hopefully, someone has an idea or a how-to for me.
Thanks in advance.
Regards,
Christoph
Edited by: BigTicket on May 12, 2010 9:36 AM

Hi BigTicket.
A suggestion to trigger the BAPI / WebService at the IDoc receiving is to use a user exit or enhanced inside the idoc function module. When the idoc arrived to the idoc port the system start the related function module and then your user exit/enhanced in which you invoke your BAPI.
I hope this help.
Ciao.

ABAP web services

HIII..
I want to know about a ABAP web service . How this can be created????
Thanks in advance.
Regards
Mayank Saxena

Hi,
Web Services
Business processes consist of individual process steps that can vary in how extensive they are. One or more functions are then assigned to these steps; an executing software component is then assigned to each function. Clearly, the heterogeneous nature of system landscapes in enterprises makes it impossible to implement all the necessary functions associated with a complete process using the same technology on the same component. A modern software infrastructure must be in the position to integrate functions, implemented on widely differing software components, in one effective complete process. Until now, the combination of different applications has largely been based on manually declared interfaces, message formats, and agreements between business partners.
Web services simplify this process. They are based on open, generally accepted standards. They enable you to combine functions in a single process, even if they are implemented in widely differing software components. Web services are standalone, executable entities that can be published, searched for, and called, across a network.
Introduction
The SAP Web Application Server implements the following basic Web services standards: eXtensible Markup Language (XML); Simple Object Access Protocol (SOAP); Web Service Definition Language (WSDL); and Universal Description, Discovery, and Integration (UDDI).
In the documentation that follows, we assume that the reader is familiar with Web service standards and techniques. You will find a general introduction to the Web Services topic under Sun Microsystems, in the pages of W3C, and in the general explanations for standardization organization OASIS under the topic UDDI.
Integration
ABAP and Java Web Services
Enterprises can extend their solutions by using Java or ABAP Web services, or both. If your priority in programming an application is the selection of data, the integration of an ABAP Web Service could be appropriate. Conversely, if you are implementing processes that involve different business partners and systems, it may be beneficial to program in Java and integrate Java Web Services.
The Web Service Framework consists of:
·        The development environment for the ABAP Engine
·        The development environment for the J2EE Engine
·        Tools that support UDDI registration
·        A distributed, interoperable SOAP runtime (ABAP and J2EE Engine)
Processing of SOAP requests using the Internet Communication Framework
Web Services and the SAP Exchange Infrastructure
The SAP Exchange Infrastructure is a key area in SAP NetWeaver. The Exchange Infrastructure provides an open, process-oriented integration infrastructure for the unhindered flow of information and for XML-based message exchanges. Systems integrated using SAP XI exchange messages over the Integration Server.
The programming model for XI ABAP proxies and Web services has been unified. The advantage of this is that both technologies can be implemented so that they complement one another. Messages can be sent and received either using the XI runtime or the Web service runtime.
Additional proxy runtime services can be controlled using protocols that you request using a proxy method. The features you have available depend on whether you are using the Web Service Framework or the Exchange Infrastructure for communication.
Features
The ABAP Workbench offers an environment where you can publish, search for, and call Web services. It enables the SAP Web Application Server to act both as a server and client for Web services.
The Web service infrastructure enables developers to:
·    Publish independent function that were implemented as RFC-enabled function modules, function groups, BAPIs, or XI message interfaces. This includes functions available as part of mySAP.com solutions, or functions developed by customers or partners. The Web service can be used across the entire Internet using standard protocols and can easily be added to any development environment. (See also Creating a Web Service).
·    Consume Web services, regardless of where they are stored or how they are implemented. Business processes can be implemented across several systems, either within an enterprise or across several enterprises. (See also Consuming Web Services.)
The following triangle shows the basic architecture of the Web Service Framework:
Service Provider
After the functions have been implemented, a Web service interface must be created that provides a representation of the Web service for the user. This interface offers an abstraction layer and thus independence from the specific implementation used. Based on this interface, the Web service is configured and can be called at runtime. Publishing Web services in a UDDI Registry is supported by the UDDI client functions in the SAP Web AS.
Service Directory
You can store Web service definitions and released Web Services in a UDDI Registry. WSDL documents provide the basis of the Web service client, which can then be searched for in the UDDI using either a browser or the standard UDDI APIs. Web services can be published and searched for in all registries that conform to the standard. SAP also offers a public UDDI Business Registry under uddi.sap.com.
Service Requestor
The SAP Web AS allows you to integrate Web services. It can generate Web service clients from WSDL files.
Standardization and Extensibility
Web services and Web service standards develop quickly; new standards are being presented continually at standardization committees. However, these extended standards such as security standards or additional protocols can easily be integrated in the Web Service Framework using SAP.

How to consume the Abap web service in Java web-dynpro

Hi Everyone,
I want to consume ABAP web service in java web dynpro.
so when i tried to create model in java web-dynpro, it gave me an error message saying "Invalid WSDL or WSDL not found".
i think this error message is because, to access the WSDL of abap web-service, we need username and password, but the dialog box in java web-dynpro is not programmed to take username and password from us and send it to the server to get the WSDL.
i came to this conclusion because i was able to successfully test my abap web-service in java portal. the java portal asked me the username and password to open the WSDL.
So, please help me to consume the abap web service in java web-dynpro.
Thanks in advance
Regards
Vikas

Hi Vikas ,
while creating a model in web-dynpro try to use the "import web service model" option and if you are using local server choose the local server option so that you can get the available web services which are in server, select one among them and continue you process.I think this is the some what easy way .
If you want use the URL for wsdl better to once test the available service in server and copy that WSDL URL and paste over WSDL textbox.
I think this is pretty help ful to you
