Error in calling RFC

Dear All,
In one of my scenarios I have called RFC to my R/3 server. But now ita throwing an error mail that user id/password locked. I am checking the messages in SXMP_MONI and it is showing the following description.
com.sap.aii.af.ra.ms.api.DeliveryException: RfcAdapter: receiver channel has static errors: can not instantiate RfcPool caused by: com.sap.aii.af.rfc.RfcAdapterException: error initializing RfcClientPool:com.sap.aii.af.rfc.core.repository.RfcRepositoryException: can not connect to destination system due to: com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed Connect_PM TYPE=A ASHOST=10.6.4.55 SYSNR=00 GWHOST=10.6.4.55 GWSERV=sapgw00 PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR partner not reached (host 10.6.4.55, service sapgw00) TIME Sat Mar 17 07:46:10 2007 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -10 MODULE nixxi_r.cpp LINE 8684 DETAIL NiPConnect2 SYSTEM CALL SiPeekPendConn ERRNO 10061 ERRNO TEXT WSAECONNREFUSED: Connection refused COUNTER 4
Can u please suggest what is the error and how can it be solved.

Error while calling RFC when using BSP Web Interface

Hi,
we have a problem with the Authorization when we use an Web Interface for BSP. We have assigned all roles to the user which were mentioned in the SAP standard documentation:
R_AREA
R_METHOD
R_PACKAGE
R_PARAM
R_PLEVEL
R_PM_NAME
R_PROFILE
R_STS_PT
R_STS_SUP
R_WEBITF
S_RS_ADMWB
S_RS_AUTH
S_RS_COMP
S_RS_COMP1
S_RS_DAS
S_RS_ICUBE
but we still get the error message: "Error while calling RFC".
When using a user with SAP_ALL, it works.
What can we do?
Thx for your time.
Joerg

Actually that's surprising - because BSP (Business Server Pages) and RFC (Remote Function Call) are not related; they use totally different transport protocols (http vs. RFC). Even if an BSP application is calling a function module remotely (acting as RFC client) no authorizations for S_RFC are required - in the calling system (but in the called system, i.e. the RFC server).
Since assigning SAP_ALL seems to "cure" the problem, it seems to be an authorization issue, indeed. In that case it makes sense to use the authorization trace (ST01 - notice: that's specific to one single ABAP application server; you might have to activate the trace on multiple instances) to find out which authorizations are checked / demanded.

Error when call RFC Function module in R/3

Error while calling RFC

Hi all WebDynpro Gurus
I am using EP7.
I am developing an WD application for KM functionality in which I need to call RFC from backend. I followed the "Creating WD application accessing ABAP function" example.
But when I executed the application I got following exception.
Root Cause
The initial exception that caused the request to fail, was:
com.sap.lcr.api.cimclient.CIMClientException: java.net.MalformedURLException: URL must have a host part
Correction Hints
Accessing the System Landsape Directory (SLD) failed. Depending on the concrete reason (see root cause) check the following:
is the SLD Supplier in the J2EE engine configured correctly? See the SLD documentation for more details about the SLD and about how to configure it.
are all JCO destinations maintained correctly? Use the preinstalled Web Dynpro Content Admin application to check/edit the destination. Use the Ping and Test functions of the Content Admin to verify that each destination is properly configured.
I checked JcO connections in the webdynpro content admin. There the status is unknown and create tabs are disabled.
I checked the SLD connections in content admin , the entries are as below:
Host name : blank
Port: -1
User: blank
Url: http://.-1/sld
Where could i configure these SLD settings and what should be the new entries ?
I dont have permission to view WebDynpro console.
Please help me out.

Vinod,
Claim: "Hello, World" application with WD and RFC is the "Hello, World" application with most complex configuration.
Prove:
1. You need to run http://host:port/sld and import CIM context
2. You need to add technical WebAS ABAP systems to SLD (same URL)
3. You need to run Visual Administrator and setup SLD connection parameters (host, port, user, password)
4. You need to (re)deploy your WD application
5. You need to run web-based WebDynpro Content Administrator and configure JCO connections.
Fortunately, [1]-[4] is necessary only ones per server, [5] is necessary per every application.

Error when calling RFC

When i try to call RFC in web dynpro it gives
The initial exception that caused the request to fail, was:
java.lang.NullPointerException .................................
Please guide me as i am new in dynpro field.

Hi,
This looks like a Java Web Dynpro problem, not ABAP try posting in the Java forum.
For what its worth, it would help if you posted the full Java stack trace so we can see what is actually causing the NullPointer. Typically, it may be you haven't created an element in a context that is mapped to your model, or you have a field that hasn't been initialised but without any more info no-one can really help.

Error in Calling RFC FM

Hi,
I am using RFC -> PI->HTTP scenario. PI will get the data from R/3 via RFC Function module.
When we call the program that calls this Function module in R/3 using destination as PI Server, we get the following error
"JCO.Server could not find server function
We did all the configuration that is mentioned
-Create TCP/IP Connection with program ID
-Use this same program ID in the Sender RFC CC
Register this program ID in JCO in PI
Still we are getting this error in form of dump in R/3
Normally when we use the RFC Function module, the FM should exists in both source & target. Does this also required in case of PI because the dump on PI says Function cannot be found in the library.
Please advice.

hi,
there might be two problems...
1) check whether u have Created RFC destination of Type 'T'. properly from ECC to Xi,
2)RFC u r Login credentails having Remote user Authorizations in the RFC destination From ECC to XI.
proerly follow these steps
To make ur TCP/IP RFC destination work, follow steps as below,
1. Enter information like, gateway host, gateway service which you can find using transaction smgw.
2. Select Registered Program Id option button and enter any string as a program id.
3. Now go for configuring communication channel. Provide same parameters for Gateway, Gateway Service and Program Id.
Provide rest all required info like application server, system number, user name , password etc.
4. Now activate your communication channel.
5. Go back to your RFC Destination and now test your connection. It should be working.
Before testing your RFC destination, don't forget to ACTIVATE your communication channel.
try to use FM which sending some on execution....
Thanks,

Error in executing RFC or CAF Application Service

Hello Everybody,
I am creating course approval process, in which I am calling RFC for user info and after course approval, calling CAF application service to persist this data.
But, both services are not working in process. I have tested callable objects for these services and tested successfully.
But, when I am attaching it in the process then process can't go forward from this point.
I have checked in Log viewer and found following error:
Path to object does not exist at com.sap.caf.eu.gp.model.pfw.local, the whole lookup name is sap.com/com.sap.caf.eu.gp.model.pfw.local/GPUWLBridge.
What should be the problem in this?
If I remove these services then whole process works fine.
Thanks in advance,
Bhavik

Hello All,
Is there any concept like, I call perticular backgound object first time then I cannot call that object for some period of time?
I am getting same error in calling RFC callable object as well as CAF service callable object.
I can execute these callable objects in the process first time successfully. But, When I execute this process second time, these callable objects won't execute.
I can execute same process after 3 to 4 hours successfully once.
What should be the reason behind this?

Finding an error while calling an RFC

Hi,
My requirement is as follows.
The internal table(ITAB) which i am using has a field X of length 20 and the Internal table(RFCITAB) field Y found the RFC is of length 10. Here i am creating another 3rd internal table(ITAB1) with field Z of length 10 and i am moving the content of field X from ITAB to ITAB1 and i am passing Z value of ITAB1 to the RFC.
While executing it i am getting the error 'Interface data error'.
please let me know why this error is getting populated.

Java call rfc check in original:error while checking in and storing.

hi,experts.
java call rfc check in original:error while checking in and storing. BAPI in the RFC is "BAPI_DOCUMENT_CJANGE2",
the RFC was fine in SE37 and calling by Visual Basic. and in java,when mConnection.setAbapDebug(true), and runing by step and step, was fine too.
if mConnection.setAbapDebug(false) in JAVA, up error in title was displayed.
what cause this error?
Best Regards.

Hi Priya
Please use Su53 after getting the error and find any authorization is missing for the user..
S_GUI Full Authorization is required..
Since by giving BASIS Authorization its rectificed, then it shud be mostly due to Auth issues only

Error with Asynchronous RFC call to JDBC

Hi all,
We are working on a scenarion where in we have to make an asynchronous RFC call to JDBC.
We have configured RFC sender adapter following this weblog
/people/michal.krawczyk2/blog/2005/03/29/configuring-the-sender-rfc-adapter--step-by-step
We have created data types only for the database as RFC does not require any data types.
And also we have created message types,message interfaces accordingly.
In Message Mappping,we mapped the export parameters of RFC to the access fields of database message type.
Also we have created sender agreement,interface determinations etc.... accordingly
And for sending RFC request asynchronously we followed this weblog
/people/swaroopa.vishwanath/blog/2006/12/28/send-rfc-to-sap-xi-150-asynchronous
Once done with all the above steps we could able to trigger the RFC call and caught with the following errors in SXMB_MONI and no errors are seen in communication monitoring

I did not map the RFC import parameters,do we need to do that
Any help in this regard is really appreciated
Rgds,
Santhosh

Hi,
I am really happy to hear that the problem with mapping is resolved.
Now as per your requirment It needs to be aynschornous RFC--> XI ---> JDBC call. In XI you should map the RFC Export parameters to the traget structure of JDBC.
then the question is to how to trigger the RFC Function Module in R/3 to XI.
Plesae follow below steps to trigger it from SAP R/3
1. Create a RFC in the R/3 system
2. Configure the SM59 and Sender Communication channle as given in the Michal's blog. Also test if it is succesful.
/people/michal.krawczyk2/blog/2005/03/29/configuring-the-sender-rfc-adapter--step-by-step
3. Import the RFC in XI
4. Do the mapping to the target strucutre
5. Configure the JDBC receiver adapter
/people/sameer.shadab/blog/2005/10/24/connecting-to-ms-access-using-receiver-jdbc-adapter-without-dsn
6. You can trigger the RFC from R/3 sytem by using
Async Call - in ABAP program use below syntax to call RFC. Here the export parameters will be passed on to XI which further have mapped to JDBC.
CALL Function "RFC Name" IN BACKGROUND TASK destination <sm59 destination>
COMMIT WORK.
Sync Call
CALL Function "RFC Name" destination <sm59 destination>

Error in BPM: "COMMUNICATION FAILURE" during JCo call. Error opening an RFC

hello experts
i am receiving the above error incase of BPM scenario where i am having a Transform step and synchronous RFC step.
i referred to the few threads discussing such problems and was trying to find whether my mapping is correct and i tested my mappings using my payload which looks good.
When looked into the Mapping trace of the BPM "Show container" i found error ""COMMUNICATION FAILURE" during JCo call. Error opening an RFC connection" and it seems that when BPM is attempting to call interface mapping it is throwing this error.
Thanks in advance.
Regards
rajeev

hi,
I think no problen with the mapping part,
jco connection requird when xi try to stablish the connection with the adapter .
please look the link provided.
Setup and test SAP Java Connector outbound connection
please also check the following parameter at the exchange profile
com.sap.aii.rwb.server.centralmonitoring.r3.ashost
com.sap.aii.rwb.server.centralmonitoring.r3.client
com.sap.aii.rwb.server.centralmonitoring.r3.sysnr
com.sap.aii.rwb.server.centralmonitoring.httpport
these parameter must be given properly.
if every thing is ok than and problem still exist than try to restart the system.
for us after restarting its worked fine.

navneet
