How web services support SAP transactions

Hi ,
How does webservices technology support SAP t-codes?

Raju

Yes and no. <a href="http://www.w3.org/Protocols/rfc2109/rfc2109.txt">rfc2109</a> . This means that cookies provide a kind of session and therefore state, which can be hold on server side.
SAP ABAP ERP holds session:

"WSDLs - There are two kinds of WSDLs Standard and SAP WSDL. The standard WSDL is provided for those users who will use tools from other vendors to create clients. For SAP users, there is an extended SAP WSDL. This is an extended version of WSDL and can be parsed using SAP tools (SAP Proxy Generator), thus providing information about additional Web service requirements such as authentication, session, and so on."
for me is also the technical implementation - how is the webservice session managed on server and on client - not totally clear. If someone can help me to find exaxct technical details. Unfortenately I also always used it (esp. with Web Dynpro) without thinking about details.

How Web Services support transactions ?

Hello,
I have this questions:
- Web services support statefull?
- There is some specification about 2PhaseCommit for Web Services?
- How Web services handle transactions (commit, rollback)?
- How can I handle commit across multiple systems (using web services)?
There are standards that support this topics?
Best regards,
Luis Carlos

How to publish a SAP Web Service in SAP XI/PI 7.0

Hi,
First I've to say that I'n new in this deals with SAP Web Services and SAP XI/PI.
I've created a Web Service with TX SE80 using a standard BAPI.
I've created the Client Proxy with TX SE80.
I've created a Logical Port wiht TX LPCONFIG.
I've tried this is SOAMANAGER but I have this error...
"SRT Framework exception: Uninstantiated object "subject sidl service" in method IF_SRT_WSP_CONFIG_SIDL~CREATE_CLNT_CFG_FROM_WSDL_D of class CL_SRT_WSP_CONFIG_SIDL"
I would like to publish this service in my SAP XI/PI 7.0
How can I solve the error in SOAMANAGER?
How can I publish de SAP WS that I've created in SAP XI/PI?
Thanks a lot.
Waiting for your news.
Fernando.

Hi Dimitri,
I had the same problem:
"SRT Framework exception: Uninstantiated object "subject sidl service" in method IF_SRT_WSP_CONFIG_SIDL~CREATE_CLNT_CFG_FROM_WSDL_D of class CL_SRT_WSP_CONFIG_SIDL"
And by following Nags hints I got solution:
1, On the system where is your service provider, run transaction SICF
2, Execute this transaction
3, Go to node: default_host/sap/bc/srt/wsil
4, Right click on "wsil" -> choose "Test service" - web browser should open with XML definition of service
5, Find your service provider. In my case it looks like this:
<service>
<name>ZTEST_WS</name>
u2212
<wsdlNamespace>
urn:sap-com:document:sap:soap:functions:mc-style/service
</wsdlNamespace>
<wsdlName>service</wsdlName>
u2212
<wsdl>
http://xxx.yyy.com:8000/sap/bc/srt/wsdl/srvc_DF838C999AA282F18829001CC4D74176/wsdl11/service/ws_policy/document?sap-client=800
</wsdl>
</service>
5, Look for WSDL link -> in my case:
http://xxx.yyy.com:8000/sap/bc/srt/wsdl/srvc_DF838C999AA282F18829001CC4D74176/wsdl11/service/ws_policy/document?sap-client=800
I dont know why, but this link is different like WSDL link in service definition which I can see in SE80:
http://xxx.yyy.com:8000/sap/bc/srt/wsdl/sdef_ZTEST_WS/wsdl11/ws_policy/document?sap-client=800
6, Use this link (from "wsil") instead of link from SE80 in SOAMANAGER to create logical port
7, Yours logicall port should be created without errors.
My question - have anybody idea, why this links are different and why only that second one works?

Hi Friends,
It it possible to call web service from SAP 4.6 c..If yes how
Thanks in Advance.
Murali Krishna K

It is not possible to directly call a web service from SAP 4.6c.
Indeed, web service enablement is available as from Web AS 6.20, thus as from SAP R/3 4.7
So as described above, the solution is indeed to make use of PI(XI) for this.

thanks in advance

Thanura

Hi Thanura,
Please be specific about the ERROR?
I can not see any error in the response you have paste here. The HTTP retrurn code 200 means the execution of the webservice is successful.
If the problem is that you are not getting the values in the return code then you can try the followings-
1. Try log-in using SAPGUI directly into SAP system and execute the RFC by providing the same parameter as you are sending through POST.
or 2. Try putting a external breakpoint in RFC. Then execute the call to webservice and check the values it is receiving and returning back.
By the way, what is the client you are using to invoke the webservice. Is it HTTP DOM?
Regards.
