RFC_ERROR_SYSTEM_FAILURE

Try to execute a function (ECATT_EXECUTE) with JCO.
It is okay, when SAP system ist Release 6.40 but on a SAP 7.0 system it fails with:
com.sap.mw.jco.JCO$Exception: (104) RFC_ERROR_SYSTEM_FAILURE: Zugriff über 'NULL' Objektreferenz nicht möglich.
     at com.sap.mw.jco.rfc.MiddlewareRFC$Client.nativeExecute(Native Method)
     at com.sap.mw.jco.rfc.MiddlewareRFC$Client.execute(MiddlewareRFC.java:1242)
     at com.sap.mw.jco.JCO$Client.execute(JCO.java:3816)
     at com.sap.mw.jco.JCO$Client.execute(JCO.java:3261)
the execution of the function was started in SAP without problem, but the error occurs most recently by getting the results.
What can i do ?

thanks for the hint, but is this also the solution of our problem ?
When Debugging the ECATT_EXECUTE-Function we see, that the problem is after
this Statement (line 800 in ECATT_EXECUTE):
IF e_result_xml IS REQUESTED  (seems to be true, how can we set this to false ?)
  CALL METHOD cl_appl_ecatt_log_to_resrep=>get_log_data (here it crashs, no return from this method, ECATT_EXECUTE doesn't continue)

    Greetings All
    I am doing a CRM upgrade and I get this exact same error.  The DDIC passwords were changed in the 000 client and 001 clients from the default.  (question how do I check the shadow system?)  I updated the parameters in the SAPup via
    set DDICpwd
    set shdDDICpwd
    and yet I still get the error
    Should I reset the DD pwd to the SAP default then update the SAPup parameter with the new password?
    I check the function module  SUBST_GET_UVERS on se37 for execute the test and execute and the table returns with 0 entries under Tables.
    TT_UVERS  Value  0 entries
    Is this the problem?  If so how can this be resolved?
    Please help, any feedback is much appreciated. 
    ps...how and where do I find the RFCCHK_INI.LOG file?

  • RFC_ERROR_SYSTEM_FAILURE error while  updating the sick leave in MSS

    Hi Guru ,
    We are  getting  RFC_ERROR_SYSTEM_FAILURE error while updating the Sick leave for team member from portal .
    Please tell how to resolve this .
    Dump part :
    Runtime Errors         MESSAGE_TYPE_X
    Error analysis
        Short text of error message:
        System error
        Long text of error message:

    Information on where terminated
        Termination occurred in the ABAP program "SAPLHRTIM00_TMWBUFFER" - in
         "INITIALIZE".
        The main program was "SAPMSSY1 ".
        In the source code you have the termination point in line 55
        of the (Include) program "LHRTIM00_TMWBUFFERCB5".

    When an RFC fails from the portal to an SAP Backend, probably ECC 6.0 in your case, there are a few options that I use to troubleshoot:
          1. Ensure that all your jco's are set up ok, passwords, ect. JCOs do not appear to be the problem here
          2. Have an ABAP programmer review where the RFC is failing on the Backend System
          3. Set up an External Breakpoint in the backend RFC. Step to do this:
                   a. Get the Backend UserID of a test portal user that is having this issue.
                   b. Ensure that test user has "Debug Display" access in the Backend System
                   c. Log into the Backend system, go to SE 37 and display your RFC
                   d. Go to Utilities --> Settings --> Debugging in the top menu and add the Test User ID to the "Users" field.
                   e. Set an external breakpoint any where you want in the RFC.
                   f. Run the Leave request as the test user.
                   g. a new SAP GUI screen will popup once it hits the breakpoint. The portal browser will stay frozen until you step thru the ABAP program.
      Option 3 may sound like alot at first if you never used it, but if you are responsible for troubleshooting portal issues like this one, it is a skill you must have. You can also have an ABAP resource responsible for external debugging when you come accross issues like these. It helps you see exactly what data is being passed in from the portal and what is happening to cause the error.

    Tom

  • PI 7.31 (single stack) posting to RFC configuration gives this error: om.sap.mw.jco.JCO$Exception: (104) RFC_ERROR_SYSTEM_FAILURE: String index out of range: 0 (raised by system extern ...

    Getting cryptic error while trying to post to a custom RFC from PI 7.31 single stack.
    com.sap.mw.jco.JCO$Exception: (104) RFC_ERROR_SYSTEM_FAILURE: String index out of range: 0 (raised by system <extern>|pidevhost)
    Does anyone recognize this error and/or know of detailed instructions for registering custom RFCs in PI 7.31. I could possibly have configured the target wrong but no error says so.
    This is a File-->PI-->RFC scenario. The file processing is super simple and a configuration I have used successfully before. I would assume I'd get a different error if it couldn't parse the file.
    Jody

    Not shure if you already did but try getting some details with XPI Inspector. Also increasing log level for this category might help. You also may wanna check authorization (even if this should show with a different error text) in ECC using ST01.
    My guts feeling is that there is something wrong with payload / signature of RFC.
    Cheers

    Hi Serge,
    Two doubts:
    - Does your RFC work when you call it directly from the SE37 puting the same input parameters used by Java application?
    - Was the RFC changed after the coding of Java application? If so, the interface between Java and RFC must be regenerated.
    Regards,
    Rodrigo.

    Hello,
    Few steps to trace the exact issue :
    -first test the connection between SAP & 3rd party without any RFC call.
    -  If it works fine,then  check RFC(if not stanard )is active in SAP & working properly.
    - check the parameter values if the value types are correctly referenced.
    - Generally this error shows that something wrong with SAP system RFC call /Check whether function is remote enabled or not.
    Hope this helps.
    Thanks.
    Mark points if helpful.

  • RFC_ERROR_SYSTEM_FAILURE: The function module "DD_DTEL_GET" cannot be used.

    Hi there,
    I´m trying to launch NWCE 7.1 Webdynpro applications accessing ABAP function with no success.
    The landscape consists of an SAP NWCE 7.1 EHP1 (Trial) and an SAP NW 2004s ABAP (Licensed). NW2004s is configured as Gateway and Message Server for the SLD. I can ping/test JCOs successfully and the SLD seems to work fine. RZ70 and SM59 show no errors in the "R3" side and both systems seem to be well-registered as Technical Systems.
    I have done some simple examples in Developer Studio to ensure that the conection between both stacks is going well, but I have allways the same issue regardless using ARFC/ARFC2, new projects/old existing projects, etc.
    When I test for first time the application, the following exception is thrown:

    Then, editing the application in Dev. Studio, if I delete tables and/or single fields binded to model context, the last exception doesn´t appear any more but the application enter in the catch section executing the BAPI call:
         try
              wdContext.currentBapi_Flight_Getlist_InputElement().modelObject().execute();
         catch(Exception ex)
              wdComponentAPI.getMessageManager().reportException("Execute error."+ex.toString()+ex.getMessage());
              StackTraceElement errores[] = ex.getStackTrace();
              String errorSTR = new String();
              for (int i = 0; i < errores.length; i++){
                   errorSTR += errores<i>.toString() + "
              wdComponentAPI.getMessageManager().reportException(errorSTR);
         wdComponentAPI.getMessageManager().reportSuccess("After catch.");
         // Resynchronise the data in the context with the data in the model
         wdContext.nodeOutput().invalidate();
    The first two exception seem to be related each other, and it is true that FM "DD_DTEL_GET" is not RFC enabled in R3. Should it be RFC enabled?
    As far as I know, one of the JCO conectors is used for retrieving metadata, that is, data related to types, lenghts, etc. The FM "DD_DTEL_GET" is used for that kind of operations and the second exception is related to that aswell (com.sap.mdi.ddtypes.DDDataelement.getDescription).
    I don´t know what else should I test in order to launch an RFC function from WDJ and the trial version is about to expire!
    Does anyone know about any oss note or any other tips related to this issue, please?
    I am going to test the conectivity via Visual Composer and see whether it´s possible :S
    Let me know if you need anymore info about the situation.
    Thanks a lot!

    Hi again,
    The issue hasn´t been solved yet :(.
    After applying Note 1244067 the function module has the RFC flag checked but the Null Pointer exception are still there.

    Language resources data in the webdynpro are: Current locale = "es", Default VM locale = "es_ES". The backend default language is "EN". Could this be a problem in order to retrieve descriptions or any other language dependent data?
    Thank you
