There is a requirement where an acknowledgement should be sent to the source system as soon the service is hit, and this service should then continue processing rest of the flow.
This service uses operational branching to call other proxies. We used publish activity to send the request to downstream and then immediately after publish, used reply activity to send acknowledgement to source. But the acknowledgment is sent after the processing completes in downstream system.
Any way to break the transaction between the 1st service that is called and the next downstream services this 1st service calls?
How to achieve this other than using queue.
