Hi All,

I am trying to implement the new NW BPM Scenario(I am fallowing the Williams Document as it is), When I try to trigger the message it's getting failed at BPM XI channel level , this is the below error .

Delivery of the message to the application using connection JPR failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: Error processing inbound message. Exception: Error while proecessing request. Setting message to status failed

"System Error Received. HTTP Status Code = 200: However System Error received in payload ErrorCode = GENERAL ErrorCategory = XIAdapterFramework Parameter1 =   Parameter2 =   Parameter3 =   Parameter4 =   Additional text = com.sap.engine.interfaces.messaging.api.exception.MessagingException: Error processing inbound message.
