When a breakpoint is placed at a particular activity within the workflow and the Step Over function is used, the Executor will move to the next activity in the sequence.
Given the context of the REFramework, after stepping over the "Invoke InitAllSettings" workflow, the next activity that would execute is the "If in_OrchestratorQueueName ..." activity, assuming there are no activities in between within the "InitAllSettings" workflow itself.
Step Over will not go into the invoked workflow but will move to the next activity at the same level of the workflow where the breakpoint was placed.
