Exception Flow

When an exception is raised, the application is aborted and the flow restarts in the Error Handler that first handles that exception, according to the exception handling mechanism. The exception flow starts with that Error handler. You should consider the following guidelines:

In an action flow: the Exception flow cannot cross the main flow of the action. In this situation, a verify error occurs and the eSpace is not valid (An eSpace is valid when all expressions are correctly defined and Verify operation issues no errors.).

The next picture presents an action flow that generates the Invalid Error Handler message:

You should not connect the Error Handler to a screen that has mandatory parameters, since you won't be able to instantiate them whenever an exception occurs. In this situation, a verify error occurs and the eSpace is not valid (An eSpace is valid when all expressions are correctly defined and Verify operation issues no errors.).
