Error in XI server: JCO_COMMUNICATION_FAILURE in Message Mapping

Hi all,

I am unable to execute even a simple scenario on my server.

The status of the message in moni is random. I get either "Scheduled for outbound processing" in,or the following error(in Request Message Mapping):

SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="">

<SAP:Category>XIServer</SAP:Category>

<SAP:Code area="MAPPING">JCO_COMMUNICATION_FAILURE</SAP:Code>

<SAP:P1>Error opening an RFC connection.</SAP:P1>

<SAP:AdditionalText />

<SAP:ApplicationFaultMessage namespace="" />

<SAP:Stack>&quot;COMMUNICATION FAILURE&quot; during JCo call. Error opening an RFC connection.</SAP:Stack>

<SAP:Retry>A</SAP:Retry>

</SAP:Error>

I tried deleting the queueus in smq1 and smq2.It did not solve the problem.The test connection for INTEGRATION_DIRECTORY_HMI in sm59 is also working properly. But I don't see any entries for t-RFCs in sm58.

Can anyone tell me what could be the problem?

Regards,

Puloma Chaudhuri.

    Hi Puloma,

    1. go to TCODE: SWEL and check if you have any errors over there

    2. go to TCODE: SWF_XI_CUSTOMIZING

    - maintaint runtime environment

    - configure RFC destination

    and check if the password for user WF-BATCH is correct

    Regards,
