Http-to-rfc is it possible

A Source System will submit Material data as Http request to XI. XI submits data to the SAP System in synchronous and receive the response to the system in the required formatvia RFC. This is my scenario..

Error occurs in HTTP to RFC

HI,
When doing the exercise in TBIT40, I meet with a problem in HTTP to RFC. It always returns me such error msg in the html client: <SAP:Error><SAP:Category>XIAdapterFramework</SAP:Category><SAP:Code>MESSAGE.GENERAL</SAP:Code><SAP:AdditionalText>com.sap.aii.af.ra.ms.api.DeliveryException: java.lang.NullPointerException</SAP:AdditionalText></SAP:Error>
I don't know what's the exact reason for that, however, I am sure the BAPI program is not called. Using SXMB_MONI, we can see the response message (from Service: HEDCLNT001 Namespace: urn:sap-com:document:sap:rfc:functions Interface: ZBAPI_PO_CREATE) with above error and no XML payload at all. There's no error in the request message. I suspect if the communication channel is not created correctly as the document doesn't give a clear description on creation steps.
My question:
1. Is there any method to test if the RFC could be called properly from XI side using the communication channel I created?
2. What is the possible reason for the error I just met with? Any available solution?
Thanks & Best Rgds,
Jerry

Hello Guru's,
I want to perform simple HTTP to RFC scenario. Can any one tell me the steps for this scenario. Explain me with your example but is should be understandable for the beginners.( please don't ask my requirement ).
If possible give me the link of blogs for this scenario.
Thanks in advance.

HTTP to RFC scenario with URL parameters

Hi All,
I am working on HTTP to RFC scenario using an interface in SAP PI.
The data will be pushed from API link via 4 URL parameters viz. UID, mobno, phone1, phone2.
My query is what will be the UDF code for the same.
Also how to design & configure the same scenario in SAP PI, since I'm working on this scenario for the first time.
on SAP end, what will be more comfortable to have RFC or Proxy?
Thanks & Regards,
Amit S Patil

Hi All,
In case of RFC to HTTP scenario wherein we have to pass URL parameters as the request instead of XML/xsd(at the receiver end), there is no need of .xsd file to be imported in SAP PI as target end in request message mapping.
Similarly in reverse case(HTTP to RFC scenario), if some data will be pushed from external system through URL parameters instead of XML/xsd(at the sender end), how the design & configuration is done in SAP PI?
Is this reverse scenario possible without any XML/xsd scema at the sender end?
Please suggest me at the earliest?
Thanks & Regards,
Amit S Patil

Logon Error Message ( HTTP to RFC )

Hi all,
While I am practicing HTTP to RFC Scenario..
When I SEND data from test client ..It is asking for SAP Web Application Server (SID)
User ID and Password..
When I am giving my XI ID and Password ( and also i tried BASIS ID ,J2ee_admin, Even i assinged ROLE SAP_XI_APPL_SERV_USER ) it is giving Error like this
-->Logon Error Message
-->Error Code: ICF-LE-http-c:001-l:E-T:1-C:3-U:35-P:35-L:3
-->HTTP 401 - Unauthorized Your SAP Internet Communication Framework Team

These errors I am getting..
please guide me to complete this scenario.
Thanks in advance,

( I am unable to search SDN ,due to some upgradation is going on )

Hi Sreeramoju,
1. HTTP-401 :
 If the Integration Server is accessed by means of an HTTP proxy server,the credentials must match those that you made in transaction SICF in the Integration Engine. If you do not specify a user and password combination, or the combination is invalid, the system will terminate each attempt to access the Integration Engine with the message Transport Exception: http-Error 401 Unauthorized.
The user must have the authorizations of group SAP_XI_APPL_SERV_USER on the Integration Server.
If you want to use a different client or language to the default setting in the Integration Engine when logging on, you can also set the following parameters:
○ XI.Client=<client-no>
○ XI.Language=<language-id>
2.HTTP 407: Proxy Authentication Required" in SAP XI J2EE AE: check the SAP note: 992690
 Make sure that you have specified the proper host and port values, in the text box that appears when you check the configure proxy check box(in receiver adapter).
Looks like the webservice requires a proxy authentication.
Select the check box "configure proxy user authentication"(in receiver adapter) and provide the correct username and password.

Plz suggest me in this issue?

So that this can happen
Thank's

Hi,
1. Look into the Receiver RFC adapter and check its status.
2. Check the RFC request Message. Is it valid? Try to execute the RFC with the same data and check if it works fine.
Also refer into this blog and cross check the steps,

HTTP to RFC (Calling BAPI)

Hi,
I am working on creating a Purchase Order in SAP system by calling BAPI's from XI using RFC adapter.
I defined the following in IR:
1. Created data types for mapping with BAPI request and response.
2. Created messsage types and assigned corresponding data types to the message types.
3. Created one Message Interface (Outbound/Synchronous), Output message - request message type, Input message - response message type.
4. Create request and response message mapping and one Inteface mapping (with request tab and response tab) properly assigned.
Defined the following in ID:
1. Created HTTP business system (no communication channel)
2. Created communication channel for receiving system (SAP).
3. Created receiving determination and interface determination, receiver agreement, no sender agreement.
I sent XML message (required data to create purchase order) from HTTP client but I am getting the response as Unable to determine name of mapping program, my Interface Determination has proper Inbound Interface (ZBAPI_PO_CREATE) and Mapping program (PO_I_MAP). But Why am I getting the reposnse as I said above in my HTTP client?
Appreciate your help,
Thanks and Regards,
Jagadish.

Hi Jagadish,
The error lies in Message Mapping .So please check it once again .You have mentioned your steps it seem there is problem in Message mapping..
Please look at the following Steps..
IR:
1.Import Corresponding RFC(BAPI). No need to create Interface Objects( Data type, Message type,Message Interface ) for SAP( RFC ) system..
2.Create Interface Objects For HTTP System.As you told it is synchronous.
3.Perform Two Message Mappings
(A).HTTP Request <--> RFC Req
(B).RFC Response<-->HTTP Res
4.Perform one Interface Mapping which includes Request and Response Mappings ..
5.Activate all objects..
ID : what you have done is ok..
URL: http://<hostname:port>/<path>?<query-string> Make sure your URL is correct or not for( sender HTTP )..
I think it will hepl you , if it is solved please assign points . If you have any doubt you can call me...
Thanks

HTTP to RFC scenario

I have been trying to configure the XML to IDOC scenario given in the XI starter pack . Does anybody have the sample XML and XSD files mentioned in the scenario ?
There are two messages in the XSD, purchase order request and purchase order response. It would be a great help if anybody could supply me these XSD and also the XML test documents involved in the workshop scenaro.
Also could someone inform me what tool i can use to create custom XSD ?
Thanks,
Joe

Thanks for your reply, Honey.
I'll Try to explain my problem a little bit better :
I have data coming in from a third party system , in XML (B2MML format). I need to create an XSD according to this incoming data , and then do data transformation in the message mapping level to put this data into a BAPI call, or maybe a proxy call.
So as a beginning, i started with the starter pack scenario for HTTP to RFC . They have not provided the XSD in the PDF document that i have , so i was wondering if anybody would have the XML which i could then use.
I have come across another problem here, which is how to put the XSD on the XI server. Whenever i try to import the XSD, the file-open browser points to the XI server to pick the file from, and i dont have access to that server. Any idea how i could get around this problem too ?
Thanks ,
Joe

Looks like there is some mapping problems ,may be the RFC connection is not properly configured .Here is the link to configure the connection between ECC and PI :
http://wiki.sdn.sap.com/wiki/display/XI/ConnectionSettingsbetweenECCandPIsystem
May be there is no value retrieved from the ECC system so it is saying null value.
For proper configuration check you can refer the following blog:

I am a beginner so not the full answer is there but may be this would help you.

Hi,
I have done a simple http to RFC scenario.
when i test the scenario, the message is sent but i am not able to see anything in sxmb_moni or message monitioring.
Also, the RFC adapter is working fine.
i could see the error message in the sxmb_moni earlier when there was an error in the rfc adapter.
what can be the prob?

Http to RFC or SOAP to RFC (synchronous)

Hi,
I need to connect PHP with RFC via XI/PI
Request will be send from php developed web pages to R/3 (RFC) to get data back to web page.
I think to resolve this scenario 1u2019ve two options
1: SOAP to RFC (synchronous)
2: HTTP to RFC (synchronous)
Can you please suggest me the scenario?
Thanks for you time
Regards,
Farrukh Ghani

Hi Ghani,
The two options you mentioned we can use,but it depends on how PHP web site going to send data,if it is going to send webserive then use SOAP adapter,you are expecting response ,the RFC wil work as synchronous.
If it is not Web Service other option is HTTP,receiver would be RFC only.
How to configure SOAP->XI>RFC or HTTP->XI-->RFC scenarios,simple search in sdn will give many blogs,search in sdn,
if you unable to find right one let me know..
