RFC Error while trying to access function module from business connector

[Former Member]

Hi,

I am getting the following RFc exceptions in BC server when we invoke the service pub.sap.client:invoke fail as a flow step in Idoc_Status_Add(this service is calling a function module in sap namely ZYBC_IDOC_STATUS_ADD_FROM_BC which Adds status to Idoc (from Business Connector).But no trace of failures are recorded in sap side

except 1: rfc_failure in BC trace files under monitoring.I need to know the root cause of these errors as the same services have run finely later and IDOCs were also processed successfully without any problem.

com.sap.mw.jco.JCO$Exception: (104) RFC_ERROR_SYSTEM_FAILURE: See RFC trace file or SAP system log for more details

could anyone throw light on how this kind of error can be resolved and why it occured?

Thanks.

What does the RFC trace file and log say? Has there been any dump on the SAP server? Check the logs and transaction st22 in your SAP system to see if the RFC-module has dumped.

My guess is the problem is in the RFC-module, I think you should start looking there.
