INITIAL_JCO_RETURN

Hi All
We are facing a problem whenever we test our scenario (IDOC to File). Whenever the payload is of smaller size the scenario works fine, but whenever the load becomes high, then we get the following error in our Monitor,
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">
  <SAP:Category>XIServer</SAP:Category>
  <SAP:Code area="MAPPING">INITIAL_JCO_RETURN</SAP:Code>
  <SAP:P1 />
  <SAP:P2 />
  <SAP:P3 />
  <SAP:P4 />
  <SAP:AdditionalText />
  <SAP:ApplicationFaultMessage namespace="" />
  <SAP:Stack>All JCo return parameters are initial</SAP:Stack>
  <SAP:Retry>M</SAP:Retry>
  </SAP:Error>
Can anybody recommend some solution for this issue, as what are the settings we need to do inorder to overcome this problem. I did check the thread,
Error - "All JCo return parameters are initial"
and we are not transporting any object while testing this scenario.
Just to add we are using XSLT mapping, we do know that XSLT has a problem with memory when the source file is huge, but the complexity of the mapping was what made us to choose XSLT.

Hi,
I think this is probably caused by incorrect memory settings, I would strongly suggest you to make sure these are ok. Do you see any outofmemory erros in the logs?
Have a look at the performance header in the sxmb_moni for the relevant message. You can see here how much time did it take the JCO to transfer the data from the abap side and  back.
I repeat, please check your memory settings..
Regards, jaime

  • XI Error Mapping: INITIAL_JCO_RETURN

    I have an inbound with this mapping error I've never seen before. I've seen Mapping:EXCEPTION_DURING_EXECUTE, but never INITIAL_JCO_RETURN.
    What does this mean?

    Tom,
    It says that you have problems with your mapping. Check you mapping with the help of this weblog:

  • INITIAL_JCO_RETURN -error in mapping

    Hello!
    I get the following error in XI when I'm trying to send quite large IDOC in IDOC to JDBC -scenario.

      </SAP:Error>
    When I use smaller IDOC in same scenario, it works fine.
    Could somebody help me. Is there something wrong with the configuratios or parameters, which could cause this?
    Thanks in advance,
    Janne

    HI,
    This kind of error occurs when there will be huge data processing across Mapping. Your memmory consumption is being affected due to this processing.
    You need to have either optimization of Mapping object or the logice incporporated in mapping and may require to include SAP notes for the performance aspects.
    Else try to send the IDOC segments in small chunks
    Thanks

  • All JCo return parameters are initial

    Hi,
    I'm getting "All JCo return parameters are initial" on a SOAP->XI->R/3 scenario.  What could  be the cause?  This is not all the time, it's working 99.5% of the time!

    Thanks for your response, I will check with SAP.  This is not acceptable!  There are lots of traffic in our R/3 world between QAT and PRD.  I cannot just stop the messages (XI to PRD) when it's happening.  This is really strange.  I'm sure there is a way to fix this.  I will get back to you when I will find the way.
    Thanks
