Program id in RFC to webservice scenario

HI
I am trying to build a RFC to WS scenario. when we create the RFC destination in R/3 side we need to enter the program ID. How do i know what is the program id i need to enter??
thanks

Hi Sudhakar,
You can use any alpha-numeric string for the Program ID. Just keep in mind d program ID is a register Program ID that shud be registered on ur R/3 and Xi.
Now to register the Program ID on R/3 and XI automatically you have to enter the same Program ID in ur RFC destination and ur RFC adapter in Integration Directory.
Note: You can use even ur name as a program ID but that shud not be used in any other TCP/IP type RFC destination i.e dat shud be unique in ur R?3. Now use the same Program ID(Case sensitive) in ur RFC adapter.
While testing the RFC destination if the test fails just check whether you have started your RFC sender communication channel or not?
Hope this will help u

RFC - XI - WEBSERVICES scenario - Where to create RFC Destination

Hi Experts
For my RFC - XI - WEBSERVICES scenario, I have to create one TCP/IP RFC destination on R/3 system with the following details
RFC Destination Name    : XXXX
Connection Type            : T (TCP/IP)
Activation Type              : u201CRegistered Server Programu201D
Program ID                      : YYYY
Gateway Host                : R/3 Details ..??
Gateway Service           : R/3 Details ..??
My Function Module (Remote-Enabled) - u201CZZZZu201D is defined in R/3 System.
This Function Module should be communicated with the target system i.e. NW XI system
As per the Note from SAP Help: To be able to communicate using RFC, you need to define the target systems as RFC destinations in the sending system(R/3)
Target system u2013 XI Server
Sending system u2013 R/3 System
Are my details provided are good enough as per my explanation? Please guide me in this regard.
QUESTION : Where exactly do I need to create the RFC Destination(SM59)? on R/3 side or on XI side?

Refer the following link-

what are the inputs should be given to Gateway Host and Gateway Service while creating RFC Destination??
Open transaction SMGW on the R/3 system and choose
Goto -> Parameters -> Display. Beneath Attributes there will be the
entries 'gateway hostname' and 'gateway service'.#

HI
Refer this
RFC -> XI -> WebService - A Complete Walkthrough (Part 1)
RFC -> XI -> WebService - A Complete Walkthrough (Part 2)
Steps
Import the RFC meta data to PI
Import the WSDL to PI
Create MI for RFC -outbound Sync (if response is involved else Async)
Create MI for WSDL service you want type Inbound Sync (If response involved)
Create MM(external definition and RFC), IM for these
Create Sender RFC adapters with SA
Create Receiver SOAP and do necessary pipline steps

RFC - XI - WebService, scenario error in RFC Test

Hi
I am following this scenario

> The Program name which you have defined in the TCP/IP

> Admin. until you do that this will not work.
This is not needed at all.
Your RFC adapter and the TCP IP Connection should use the same Program ID. No need for registering it in the VA.
Just make sure that the Gateway Host and Service in the Sender RFC adapter and in the TCP IP Connection use the Gateway Host and service of the R3 system.

RFC to WebService Scenario doubt

Hi,
       I'm passing parameters from R/3 system RFC.. and based on that selection criteria the data will fetch from the Remote Application.. and send it to R/3.. finally my RFC will load these data into R/3 system. this is my Scenario( that means.. RFC to WEBSERVICE) so, in the reciever side i should use the SOAP adapter..
     but for these type of scenarios.. is WSDL file is   mandatory or.. with out WSDL file also can we do the scenario.. and if this is mandatory means.. how we will get the WSDL file...
        because according to my reqirement i know only the sender system (R/3) and Receiver system(Remote Application) details.. I dont know any thing about other details..
please suggest me what are the things are needed.. so, that i will get from my client..
Regards

Hi,
WSDL contains the message /data structure for you input and output.
If you know the Web Services input /output data , you can create it manually or if you have WSDL, you can directly import in IR and all the request/response message would be generated automatically.
To call a Web Service, only URL is required.
You can ask your client to provide the WSDL file.

How to create or simulate a WEB service? Scenario RFC to WEBService.

Hello PI experts,
I'm creating an interface with this scenario: RFC->PI->WEBService, the message is synchronous. The problem is that we don't have nothing at the webservice yet, I just want to know if have a way to create or simulate a webservice to test my interface? If someone have some material or information please it will be very helpfull.
Thanks

Create two scenarios.
1) Using SOAP sender you can create a web service. So create a simple scenario using soap sender and use some receiver like jdbc or file or something for your test. Create WSDL using sender agreeement and save the wsdl.
2) create RFC to SOAP scenario. In the receiver side use the WSDL as external definition for the receiver mesg structure. Configure SOAP receiver to point the soap service created using soap sender in the step 1.
Basically you need to know SOAP sender for the step 1 and Soap receiver for the step 2 configuration and design.

RFC to SOAP Scenario -- Delivery Exception

Hi All,
I am working on RFC to SOAP scenario.
On executing a program in the SAP system, the system is throwing a dump stating "com.sap.aii.af.ra.ms.api.DeliveryException: invalid content type for SOAP: TEXT/HTML".
I feel that the error is because of the response not being sent back by the webservice. On executing the webservice independently, it is working fine i.e. sending back the response.
Can anyone suggest the possible reasons for this error and what needs to be done to rectify this?
Thanks,
Ravi Kiran

the return from the Web service must have been an HTML(may be an error page or something)...What kind of authorization does this WS look for ?
Pls check these threads...

Error"SYSTEM Failure" while testing the RFC in SE37 : RFC to JDBC Scenario

Hi All,
I am doing RFC to JDBC scenario. When I am testing the RFC in SE37 using the RFC destination created in SM59, I get an error "SYSTEM FAILURE".
Please suggest.
Thanks,

Hi,
You must run RFC with RFC destination in background mode, I suggest to read following post in order to understand it better.
Syntax would be:
CALL FUNCTION func IN BACKGROUND TASK
[DESTINATION <your RFC destination>]
parameter list
http://help.sap.com/saphelp_nw04/helpdata/en/8f/53b67ad30be445b0ccc968d69bc6ff/frameset.htm
If you read it you will find that you can't test it directly from SE37, for this either you need to create dummy ABAP program or another RFC where you will call this RFC with background syntax.

Issue in File to RFC to File Scenario with BPM using Block Step

Hi Everybody,
                       I am doing File to RFC to File Scenario for multiple records using BPM using Block Step. The File Message is getting posted and after that, the message is getting stuck up in the qRFC Monitor (Inbound Queue).
                    After seeing the message in Inbound Queue, I am trying to execute and release the message. But when i execute the LUW, it says " Function module doesnt exist or EXCEPTION raised" in Inbound queue.
Could somebody suggest me the outcome of this? What does this mean and how to
release the stuck up message in Queue.
Thanks and Regards,

RFC destination for RFC to File scenario

Hi,
I m creating a TCP/IP RFC destination in R/3 system for my RFC to File scenario.
Step 1:
For this a Registered server program is created in Jco RFc Destinations with,
Program Id : pgm1
Gateway host : PI's host
Gateway service : PI's service
application server host: ECC's host
system numer     : ECC's number
client : ECC's client
logon user : ECC user
password : pwd
Step 2:
In SM59, TCP/IP connection the following parameters are given:
Program ID : pgm1
Gateway host : PI's host       -
> is this correct
Gateway service : PI's service      -
> is this correct
Step 3:
So i am calling the RFC in ABAP program (R/3 system) like:
CALL FUNCTION 'Z_HR_OUTBOUND_DATA2'
IN BACKGROUND TASK DESTINATION 'Z_HR_OUTBOUND_DATA2'
Step 4:
In PI side,
for RFC sender I am passing :
Application server : PI server
Application server service: PI host
program ID: pgm1 which was created in the previos step
For RFC Metadata Repository Parameter, i am passing all the values related to R/3
Please let me know whether the steps and values i given is correct.
B'cos even if i give ECC's information in Gateway host and Gateway service the scenario works fine and if i PI's info then also it works fine.
so i am confused as which is the correct method. pls clarify

Ok I will try to explain....
Assumptions: R3_TO_XI is the name of RFC which I created in ECC of type T.
While creating the RFC in ECC we mention a unique name which is called Progaram ID. Now the same program id we mention in our sender RFC CC.
So now when an ABAP Progarm (where you will call this RFC with it's destination) is scheduled/triggered with the code as mentioned below then since the DESTINATION ('R3_TO_XI') mentioned here contain the same program id which we have mentioned in our sender CC, invokes the adapter in PI and soon after that all pipeline steps get executed in XI.
CALL FUNCTION 'ZBAPI_COMPANY_GETDETAIL'
IN BACKGROUND TASK
DESTINATION 'R3_TO_XI'
TABLES
    comp_detail = company_detail.
COMMIT WORK.

What is RFC to XI scenario

Hi Forum,
What is a RFC-->XI scenario
When do we configure Sender RFC channel,
Does it mean calling a RFC enabled Function Module in XI from a R/3,
Does it mean executing a Function Module in a R/3 and sending the output to XI,
how do i go about writing a ABAP code for such a situation (pls provide a sample code)
How do i make a message interface in XI for the RFC message coming from the R/3 to my XI
What is the purpose of doing such kind of scenarios
pls help

Hi Sudeep
What is a RFC-->XI scenario
>> It means passing data fior RFC call to XI and XI inturn will pass the data to some other application system.
When do we configure Sender RFC channel
>> We need this when your RFC call is on sender application system and the processing is done on receiver applciation system.
Does it mean calling a RFC enabled Function Module in XI from a R/3,
>> NOP, it doesn't mean calling a function module in XI as XI is just a integration broker it wont process any data.The call is intend for other receiver systems passed via XI.
Does it mean executing a Function Module in a R/3 and sending the output to XI,
>> NOP, it is not passing output to XI.
how do i go about writing a ABAP code for such a situation (pls provide a sample code)
>>Sample code will contain call to the sender message interface in the configured scenario.
How do i make a message interface in XI for the RFC message coming from the R/3 to my XI
>> Import the RFC from the sender system to XI and then you can use that message interface in your scenario creation.
What is the purpose of doing such kind of scenarios
>> This is used when you intend to place a RFC call from a sender system to receiver system, so the processing of the RFC is done on the receiver system.
The main points to be considered while RFC to XI scenario is
1) The RFC destination is TCP and the program name mentioned in the desnation should be registered in though sender communication channel. The program name mentioned in the RFC desnation and sender commnucation channel should be same.

Error Handling on RFC - XI - File Scenario

I have an R/3 RFC -> XI -> FILE scenario that works, but does not adequately handle the error of my R/3 to XI connection being down.
The RFC call is async since I was under the impression that I had to do a "to file" scenario that way.
    CALL FUNCTION 'ZXO_SAP2RFC'
      IN BACKGROUND TASK
      DESTINATION wa-rfc_dest_1
      EXPORTING
        request          = request
        rfc_header       = rfc_header.
    COMMIT WORK AND WAIT.
    IF sy-subrc <> 0.
      [error handling]
If my rfc destination is down (for example when XI is down), this RFC call is still getting a sy-subrc of '0' (so my error handling does not kick in).
Any suggestions?

Hi Keith,
your scenario is working correctly. If XI is down you will find your message queued in transaction SM58, where you can restart it manually. Usually there should be standard job for report RSARFCEX, which is periodicly trieing to restard the message.
Asynchr Call (tRFC) means that your program continues completly undependent from that call.
Make a test: Change temporary the called machine in SM59 destination to senseless value and execute your programm. Your message should be in SM58. Then correct the destination and wait a few minutes...

Udo

I am trying to create a RFC-XI-Webservice scenarion in which i have made a function module giving the parameters which needs to be displayed in my webservice . I call this function module in a report zlv_distance.
.I am getting a dump while executing my Function module . I am copying the dump as under:-
Runtime Errors         CALL_FUNCTION_REMOTE_ERROR
Date and Time          11.10.2007 10:23:56
What happened?
     Error in ABAP application program.
     The current ABAP program "Z_WEBSERVICE_TEST_SARAS=======FT" had to be
      terminated because one of the
     statements could not be executed.
     This is probably due to an error in the ABAP program.
     The error occurred in an RFC call to another system.
     The target system has also written a short dump.
     Consult this short dump for more precise information about
     the cause of the error.
Error analysis
     An error occurred when executing a REMOTE FUNCTION CALL.
     It was logged under the name "RFC_EXTERNAL_ABORT"
     on the called page.

I have made my function module Remote enabled.
My RFC destination is working fine .
I have already tested that.
Please help me on this.

Hi,
possible solution could be a ConversionException in you RFC Adapter because of mismatching data types in your source and receiver message.
Just goto RWB an monitor the Processing Details for Cluster Node Server of your adapter in the Channel Monitoring.
Afterwards you have to adjust your importing or exporting structure of the used RFC function module.
Cheers,
André
