Error (Overflow in RFC - XI)

Hi.
I'm working with a XI -> RFC -> XI scenario.
When i send the info from XI to RFC, works fine.
When i return the info from async RFC to XI, in SM58 i get this message :
java.nio.BufferOverflowException
How can i solve this problem?
Thanks.

Error on reviever RFC side

Getting following error on reciever RFC side
Exception caught by adapter framework: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: failed to parse BAPI response due to: com.sap.aii.af.rfc.util.bapi.BapiException: Parameter with name RETURN not found.
The custom RFC used in this case has export parameter as a table containing list of matching entries. There is no export parameter by the name RETURN.

Amol

Hi Amol,
go to your RFC receiver determination and uncheck under "Advanced Mode" the fields "Commit Handling for Single BAPI Calls" and "BAPI Advanced Mode".
If you have BAPI and non-BAPI calls with the same R/3 system, you need seperate communication channels".

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 in the RFC communication when parabatch is set to more 3 (default)

Hi experts,
We have a 10 blades BIA system connecting to our BW Production. When we set the parabatch to more than the default 3 (we set to 4 or 5), We keep getting 'Batchpara Error' and 'Error in the RFC Communication: Error when opening an RFC Connection' during the initial index build. Here are what we do and what we see:
1. set parabatch to 5 and build 1 initial index (cube is 46 mil rows, 22 GB in size) - Failed with the above errors
2. set parabatch back to 3 and build 1 initial index (same cube as above)- successful but slow
3. set parbatch back to 3 and build 2 initial indexes simultaneously (16 mil rows/4GB and 6 mil rows/2 GB) - Failed with the above errors.
In the BIA index log I see the following error:
Error in the RFC communication: Error when opening an RFC connection (TREX_BIP)
Message no. STREX005
In SM37 in one of the logs I see the followings:
Parabatch Error
Any light you can shed on why we are encountering this issue will be much appreciated. Also, I observed that there is a long idle time in all systems (BIA, DB2, BW) and seemed like their respective resources were not utilized at all. Once in a while I do see surge of cpu/memory usage in all systems but not too terrible. I'm puzzled by why there is such long interval of idle time in all systems while the initial index build is going on.
BTW...we did the same thing (set parabatch to 5, and run parallel initial builds) in our non-prod BIA (2 blades) and QA BW landscape and do not have any issue at all.
Thanks!
Kee

Hello
PLease check the sapnotes and check the developer trace for more information.
Note 314530 - Number of RFC/CPIC connections for external clients
Note: 1070034
It can also be because your system has reached it its max gateway connections...also check whether you are getting error message "Communication error, CPIC return code 017, SAP return code 450
" in sm21 ???

Error Handling in RFC- JDBC sync

Hi all,
We are having scenario RFC<->XI<->JDBC(Sync),and its working fine also.
Suppose exception occur in RFC->JDBC request mapping,Now is it possible to pass the error back to R/3 ?
If parsing error occurs in JDBC adapter how to catch this error in error structure of rfc ?
We observed that if any exception occurs on request side , response mapping will not get executed can anybody explain me why this is happening ?
Thanks in advance,
Tuhin

Hi Gopesh,
U should follow the steps as below.
1.Create TCT/IP connection with t-code SM59
in R/3 and give program id (it is case sensitive also).
2.Give same program name in Sender RFc communication channel.Check that this channel is register in your R/3 system with t-code SMGW(Gate way monitor)
Only this much extra config I have done.
Thanks,
Tuhin

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?

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.

Error in Reciever RFC Adapter

Hi All,
While working with JDBCXIRFC, the only error with Reciever RFC Adapter is as
follows.
ZBAPICUSTOMER_DETAILS: com.sap.aii.af.rfc.afcommunication.RfcAFWException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: could not get functionname from XML requst: com.sap.aii.af.rfc.RfcAdapterException: failed to read funtionname from XML document: missing namespace declaration(2)
In SXMB_MONI, the messages are queued up.
How to debug this error?

1. Map all the mandatory fields..
I have mapped all the mandatory fields. If i enter same kind of values in the same fields of BAPI manually (in se37), the table gets updated.
how you can say that data is getting into the right tables...when you are sending the same data.....may be the data is old only..
Perform the Message Mapping and Interface Mapping test in IR only...
3. Kindly check the Sender_MM Mapping once more...If it is fine...reactivate and Update the cache..
Its fine and reactivated and even updated cache.
Now one doubt....
In Message mapping, the sender mesage type is as follows.
sender_mt 1:1
->Row element 1:unbounded
> zkunnr element xsd:string 1: unbounded
> zname1 element xsd:string 1: unbounded
> zstras element xsd:string 1: unbounded
> zadrnr element xsd:string 1: unbounded
> ztelf1 element xsd:string 1: unbounded
I have mapped ROW with ZBAPI_DETAILS.
the root of sender message type SENDER_MT is left as it is....
Is there anything need to be done (mapped) with this root of sender message type?
No i don't think so, what i can get from your approach is that you want to receive n similar type of records in a Message and want 2 create n different messages for each record from source structure.. 
With this status, i have tested the Test Configuration in Integration Directory. Still getting same error message as follows...
Kindly let me know the name of BAPI.
Perform the Message Mapping and Interface Mapping test in IR only...

Error Happened at RFC Server Cannot Open the Job Batch File.

We have BW 7.0 and Data services 12.1. We are scheduling a Infopackage in BW that triggers a job in Dataservices server.
We had checked the connection between Dataservices source system in BW and RFC server on Dataservices side and these connections are good. on the 3rd party sellections tab in infopackage we specify the batch file name that we exported in Dataservices server. When we execute the infopackage we get the following error.
Error Happened at RFC Server Cannot Open the Job Batch File.
This error started occuring from yesterday and prior to that it was working fine. We are not understanding what changed in the system to cause this error.
Can anyone suggest any solutions for the above issue.
Thanks,
Naveen.

I'm not sure what the root cause would be here. Is the file still available ? Did file permissions change ? ...
But I wanted to point your attention to the fact that in Data Services/Data Integrator XI 3.2 (=12.2) we significantly enhanced the integration with BW. In XI 3.2, the RFC server is now integrated into the Data Services Management Console (so no need to start as a seperate executable) and you can start jobs from BW by just specifting the job's name in the repo (no need anymore to export execution commands to .bat files). So if upgrading to XI 3.2 is an option, things should go much smoother.

Hi Ram,
Please change your password to UPPERCASE and try.
I have came across few instances where SAP converts passwords to uppercase while storing and so they dont match.
Hope this helps.

How to catch the error if an RFC fails due to short dump

Hi All,
I was calling the RFC Function module in parallel processing depends on the number of work processors available. I am getting the return message from the Function module using the perform statement
PERFORMING task_return ON END OF TASK
But I am not able to catch the errors if the RFC has been terminated due to the dump or manually killing the RFC while running.
I need how to handle the RFC if the call has been terminated due to the dump or system failure. Does the RFC return the sy-subrc at this time or can we able to catch the error in any other way.
Thanks & regards,
Vijay

Hello Vijay,
If you're calling RFC from outside SAP using the OCX-SAPFunctions-Library, then you can catch the dump or any other exception occuring in your SAP-Function.
Assuming that, objRFCFunc is the RFC-Function you can get the Excepetion-Code through objRFCFunc.Exception.
It returns a String. If the error was a dump, the String is "SYSTEM_FAILURE". If it is a "regular" Exception you'll get the Exceptioncode. E.g. "NO_DATA_FOUND".
If you need any sample code e.g. VBA-code for use in Office-Applications, let me know.
regards
Sven

SLD Configuration : Error opening an RFC Connection

Hi All,
I am working on EP6 SP19 and trying to configure SLD.
I was trying to check the data collection with the transaction RZ70,and I got the following error:
Data collected succesfully
Used RFC Destination: SLD_NUC
RFC call failed: Error opening an RFC Connection
Existing periodic jobs removed, number: 1
Program scheduled: 20070327
Event controlled job already exists,scheduling not necessary
I performed the follloewing steps:
I have imported CRContent.zip succesfully.
I have configured the data supplier bridge with following parameters.
Update local SLD (sld/active): TRUE
RFC Gateway:
Server : <host name of J2EE server>
Service : <The SAP gateway service port> (here I gave sapgw00)
This gateway service is installed while installing WAS Java.
Please clarify if I can use the same or Do I need to install standalone gateway instance?
I restarted the Data supplier bridge it is running.
I have created RFC destinations through visual administrator with
JCO RFC provider and used the same name for the program id
in RFC destination of SM59
Once the above steps are done,I am getting the error.(Error opening RFC)
Please give me a clue of wat else do I need to do?
Regards,
Santhosh

Hi,
check the following once.
How to configure the R/3 system as technical system into portal is follows.
U need to add some properties in VA.
Then only it will works.
U can goto the VA and in SLD data supplier add some properties like this.
1)HTTP settings: host = poratl host , port=50000 ,user = portal username , pwd=give thepwd.
2)RFC settings : Gateway host= poratl host and Gatewayservice=sapgw00
3)CIM client generation settings :host and port are the same as above and user and PWD same above
After this u need to check the Cimclicnt and that shows success.
And finally u need to go to the SLD add ur r/3 system properties and and ip address and host name in the host file of ur windows.
and finally add message server host in the services file in ur windows.
Have you checked the JCo destinations And SLD connetions.
If all are correct then u can add the properties in the Application server
Host file add the IP address and alias name
C:\WINDOWS\system32\drivers\etc\host
in services file add the <Messageserverhost> 3600/tcp.
C:\WINDOWS\system32\drivers\etc\services.
Then it might helps you.
Thanks,
Lohi.
