Connection problem flow of a Connect rule will trigger only when we call connect rule from flow.
The given statement is True/False?
I believe it should work outside the Flow context because ConnectionProblem Flow is at the Connector level configuration.
The activity referenced in the Integrator shape references a connector rule (for example, a Connect SOAP rule) that controls the communication and data exchange with the external system.
To facilitate the detection of problems and analysis or repair such events, you can designate a flow rule for connector exceptions in your application. Failure of an Integrator shape causes the designated flow rule to start. The flow rule can send out email correspondence, attempt retries, skip over the integrated step, or send an assignment to someone.
@RameshSangili - Thanks for the reply.
