Cannot correlate messsage

[aravindhrs]

@devkz Within the same process scope, correlation of message event is not supported.

What is difference setting message correlation inside/outside a delegate

So this is because the BPMN standard requires that a message event cannot be triggered from within the same scope. So this means that a process cannot sent a message to itself. Instead you should either look into using conditional events which are much easier to trigger from within the same scope.
