Purpose of RFC and JCO-RFC destinations

Hi,
Can you please tell me what is the purpose of RFC and JCO-RFC destinations and where do we create them.
Regards
Rahul

Hi,
RFCs are SAP interfaces for communicating between SAP systems. They accept inputs, do the processing and return the output values. You can call rfcs through different applications like web dynpro.
http://help.sap.com/SAPhelp_nw04/helpdata/en/6f/1bd5b6a85b11d6b28500508b5d5211/content.htm
JCO helps Java applications to connect and communicate with SAP backend systems. Using JCO we can make rfc calls. JCO will help in getting the rfcs in a java compatible format.

Big Problem: ABAP-RFC and JCO client

Hi Friends,
I am a java developer in trouble with a ABAP/RFC, and I dont have idea whoe lese ask for help
This is the situation:
In order to send a "candidates resume" (curriculum) in to SAP,
the ABAP developers made for me a RFC which uses the transaction PB10 (applicant master data).
The rFC when tested in the SAP GUI works fine.
I wrote a java client which calls the RFC, send the parameters and expect the results.
This client uses JCO to access SAP.
But, from the java client the RFC works PARTIALLY.
I mean, it creates the applicant, fills his name, address (infotypes 002,006,001)
but doesnt fill the education a qualifications (infotypes 22 and 24).
I am trying to figure why.
Some of the internal ABAP errors code that we get are:
DC -006
PA -054
5A -135
Also I get this message:
"Exception condition "CNTL_ERROR" raised"
Please, I am a java-per lost in the SAP land.
Thanks in advance by any help!!!
PD: I could sent you the ABAP code of the RFC or the java code of the client if necessary.

That CNTL_ERROR tells me that its trying to access a gui control which I don't is possible thru jCo. Gui Controls are very dependent on the SAP Gui Frontend. Since you are calling the transaction thru jCo, it oviously doesn't know what to do with it. Any chance that you can get a hold of the ABAP developer which wrote it initially? Maybe there is another transaction that can be used instead of the PB10 transaction.

JCO Error Unable to call RFC

Hi Experts,
I am having one WDJ application calling an RFC which has one input parameter and output as a table. When i call the RFC and
deploy the application, i am getting below error.
Could not create JCOClientConnection for logical System: WD_MODELDATA_DEST - Model: class sagia1.com.TRA_Mod.
Please assure that you have configured the RFC connections and/or logical system name properly for this model!
I checked in somany forums and tried with their solutions but not success. I tested and pinged the JCO destination which is
working fine. but ! i am getting the error when i run the application.
Thanks in advance
Suresh

Hi Suresh,
Please check that whether your WD applcation is picking correct JCO Modeldata and Metadata or not in Content Adminsitrator>>Web Dynpro>> Search here.
I think you have entered wrong name :- While creating model, you need to give porper names in
Default Logical System name for model instance (Copy here your JCO modeldata Destination name and paste it here)
Default Logical System name for RFC metadata(Copy here your JCO metadata Destination name and paste it here)
Hope it helps

JCO RFC provider and JCO connection

Hi all:
Please share your thoughts on the following doubts I have. Thanks.
1. To my understanding, we use JCO RFC provider(define in Java side) and RFC destination(in SM59) when we have request from ABAP to Java side. Then we use JCO destinations(define in Web Dynpro Content Admin) if we have request from Java to ABAP. Is this correct?
2. When creating the JCO RFC provider service, why we need to create those entries for repository for example, the server name, the user used to log into repository? What is the repository used for?
Thanks!

Hai,
your understanding of JCO RFC and RFC Destination is right.But JCO Destination gets the metadata and model data from ABAP,thats what we mention the Dictionany meta data and Application data while creating them.
Yes, we need to mention the application host,sys no,client and userdetails while creating the JCO RFC provider,then only it will fetch the data from that host and that particular client.
Thanks and Regards,

Rajesh,
     you mean to say apart from ABAP type 3 connection in XI as well as BI , I need to create TCP/IP connection in XI as well as BI ? Well In that case can you tell me when I am making the TCP/IP setting in XI, what will be the selection in
Technical setings: Activation type?
and in the gateway options, when I am doin the settings in XI server , whose gate way host and service , and am i goin to put, XI or BI .
Pls comment.

Asynchronous XI- RFC and RFC- XI scenario - strange problem

Hello XI-Xperts,
I've come to really strange problem, which I would like to share with you and possibly get an explanation.
I have an asynchronous scenario with ending XI->RFC. The RFC function in R/3 has got an optional parameter called SENDER, which when is filled, the another asynchronous RFC->XI scenario should be started. (via ABAP code CALL FUNCTION 'Z_XI_RETURN' DESTINATION gc_xi_destination ... etc.)
Now, the direction XI->RFC is configured properly, but the way back NO(!). Anyway I thought that it wouldn't make me a trouble, because those two scenarios are IMHO absolutelly separated. So I'd presume that the the data should come to R/3 without problem, it should be processed, and in case the parameter SENDER is filled the R/3 would establish the RFC connection and the "return data" should go back in different XI thread.
Well I would think like that but the situation is different:
When the parameter SENDER is empty, all goes OK and I can see in Runtime Workbench Message Monitoring - Adapter engine - Detail - Audit log only "successes". But when SENDER is filled with a value and R/3 does CALL FUNCTION with DESTINATION to a non-existing Sender agreement, the R/3 apparently doesn't send a acknowledgement to Adapter Engine of first thread XI->RFC. Intstead of that there are three messages in audit log:
MP: exception caught with cause com.sap.aii.af.ra.ms.api.RecoverableException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: JCO.Exception while calling Z_FIDATA_INPUT in remote system (RfcClient[IS2RFC_SAP_BG]):com.sap.mw.jco.JCO$Exception: (104) RFC_ERROR_SYSTEM_FAILURE: senderAgreement not found: lookup of binding via CPA-cache failed for AdapterType RFC, AdapterNS http://sap.com/xi/XI/System, di: com.sap.aii.af.rfc.afcommunication.RfcAFWException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: JCO.Exception w

Basically I understand what is happening on the background, but I really can't go over my persuation that in case of the ASYNCHRONOUS SCENARIO this should not happen.
Or is the RFC call (I mean XI->RFC) "pseudo-synchronous" even in asynchronous scenario ? I mean that Adapter engine waits for the result of RFC everytime ... ?!
Thank you
Tomas

Hello again guys,
so I've understood it on the end. My ABAP code didn't contain EXCEPTION part of CALL FUNCTION statement.
CALL FUNCTION 'Z_XI_RETURN'
 DESTINATION gc_xi_destination
 EXPORTING
 <PARS>
 EXCEPTIONS
 communication_failure = 1
 system_failure = 2.
Without it the RFC short-dumped and AE correctly tried to call it 1+3 times. The thing, that the problem was connected to XI related topic, tricked me. Well it's smart, I must admit on the end
Reward points for interest.

JCO Error JCO_ERROR_XML_PARSER

Hi All!
I am making a call to an adaptive RFC module on our SAP 4.7 System.
But i fail in executing the call.
this is the error:
Expecting a tag to begin with '<' instead of '0', in "00000000 ", error key: JCO_ERROR_XML_PARSER
I tried searching the forum for results, an saw that this error is because of an error in the metadata XML file.
But, this is Webdynpro, and as i am convinced, you are not to change anything in any XML files,
i tried making the call from to different projects, and the error is the same in both.
Anyone has any ideas ?
Help is much apreciated
Best Regards
Ronni Hostrup

Hello,
I think this is a bug in JCo & adaptive RFC here. I will asked for a redesign of the BAPI structure to get a flat structure and try that.
After searching documentation for any hints about this I can't see anything, but obviously its not working. I will open a new thread with the question, whether nested structures are allowed.

Parameter JCO.Request and JCO.Response where null

Hi ;
I try to execute RFCtoRFC scenario. I have done all settings including receiver,sender agreement too.
But when i call rfc , i get following error
parameter JCO.Request and JCO.Response where <null>
My code that the calls a remote function is like;
CALL FUNCTION 'ZBAPI_EH_GET_DATA_GEN'
DESTINATION 'OLT200'
What would be the reason ?
Thanks

Hi,
in your RFC call, specify the data which is sent as RFC req msg from R/3 system in EXPORTING parameter if your RFC call is asycnh or both EXPORTING and RFC response msg structure in IMPORTING if your RFC call is synch.........in your report, use pretty printer and specify your RFC in CALL FUNCTION and then you will see the default calling procedure of your RFC.......then create a structue for your RFC req msg structure and response msg struc and fill it with data and then execute your RFC by using this CALL FUNCTION method.........

Install the 32bit version of the Java connector. BOBJ is 32bit so even on 64bit Windows you need the 32bit version of the Java Connector.

JCO Error in Quality Portal

Hi ,
When i am running WDJ apps in dev portal , it's working fine . But when i am running through QA , it's showing the following JCO error .
Could not create JCO connection .Please ensure that you have nesured RFC destinations and/or logical system name properly for this model .
I tested the JCO in QA and it's working fine . Can anybody help me out regarding this .
And one more question , how to check JCO connections for WDJ apps inside NWDS ?
Thanks a lot .

Hi Jain,
While using RFC Models in the WD application, we maintain JCo dstinations.
These are specifically used to create a JCo Connection between 1 Web Application Server and 1 R/3 System. If any one of them changes, you need to update the same in the JCo destinations created.
The point here is, as you have changed the Dev System to QA System, i.e. your Web Application Server, you will need to create / maintain the JCo Destination with the same name on the Quality System for use of the application.
The JCo connection that you have been testing, is, may be on your developemnt system.
Hope it helps.

Alka.

File to RFC, and through RFC response i am trying to trigger the Mail adapt

Hi All,
Right now i am doing File to RFC, its working fine but now the requirement is when xi connect to ftp and picks the file need to send one success mail after the file pickup and data sent to BW system again i need to send one mail and also error alerts to inbox.
Till now i am not using BPM, can we do this without BPM pls let me know
now i am trying to achieve this in File to RFC, and through RFC response i am trying to trigger the Mail adapter.
or else i need use only BPM pls share the steps which i need to be configure.
Am i correct or pls suggest me some idea to achive this and also pls share some smaple ones in BPM .
Thanks in advance
Venkat

With BPm, follow this:

Instead of receiving the response in file, use mail adapter

RFC metadata import error - Couldnu0092t find the branch for version with id

Hi All,
When re-importing RFC meta-data, system returned following error message Couldnt find the branch for version with id = <version id>
I am not able to delete the existing (already imported) RFC meta-data. However, I am able to import the same RFC into a different Software Component.
The error is described in SAP note 710998, unfortunately, this note only references XI 2.0
Is there anyway other than these-
1) Deleting a new SWCV and importing it and then import the RFC and make Release transfer from new SWCV to Old SWCV. If so, is there any impact on my QA systems and Productions systems during transport.
2) Deleting the existing SWC and Reimporting from SLD and trying to import the RFC again and redoing all the design
3) Exporting the current SWC and deleting it and importing the same file and then trying out the RFC import.
These options I just thought as an workaround solutions. Because i am not able to try these, as i don't have any test systems for this. Let me know any suggestions on these.
Thanks in advance,
Regards,
Moorthy

Yes, the used structures were imported from an old XI system. But I created the mapping new on the PI and put the used externel definitions manually to the mapping. That worked fine but now everytime when saving the mapping this error occurs. Btw both structures are used in other mappings, too, and they can be modified without any problems.
Which jdk version do you mean? Client or server?
