Hi Amit,
Thanks for the reply. Log viewer doesn't provide much help on the error.
The error desc says
"JRA]serverExceptionOccurred. Server XI_IDOC_DEFAULT_SID, Managed_Application_Thread_58, connectionId=5-ip address|sapgw20|XI_IDOC_DEFAULT_SID, Exception: com.sap.conn.jco.JCoException: (104) JCO_ERROR_SYSTEM_FAILURE: An IDocException occurred"
regards,
Younus
