Thank you for the reply Rachit.
As per my understanding approach which you said will publish fault msg and then in offline it will read by some other component (using orch or esb portal)
My ESB itinerary does not contain Orch. It has flow like below
OnRamp (Request- Response)--> Transformations(using BRE)--> Off ramp(calling Request- Response WCF service)-->Transfomrations(RespToInternalFormat)-->Off ramp(calling Request- Response WCF service to update DB)-->Route this Response to OnRamp
Even If something fails in middle of itinerary shapes, I would like to send a response message back to OnRamp saying like "Rejected due to internal errors, contact admin"
How can I send
