also,the error recorded in the audit log is a function module name which has been defined in BC as a function map and the sap system is calling business connector to execute a particular service which is pub:client:http.
inbound mapping has been done and when sap system calls BC to exceute this service,the above exceptions are raised.

need to know the root cause of these exceptions and how they can be rectified.

also,please clarify if the exceptions
