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="" xmlns:SOAP="" SOAP:mustUnderstand="">



<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>



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?

    Hi Puloma,

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


    - maintaint runtime environment

    - configure RFC destination

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