On Start Action
The On Start action is an activity callback action that allows you to implement business rules to validate whether an instance of a process activity in the process flow can start executing its outgoing flow. An On Start action can have local variables.
If you want to stop the flow execution from being started, raise an exception using the Raise Error element. This will prevent the process activity from starting the flow execution. Learn more about how to Explicitly Raise an Exception.
