Try Catch

It helps you to configure steps which potentially raises an exception and steps to handle the exception.

The Try Catch activity contains a Try activity, a Catch activity and a Finally activity. The steps or actions that can cause exception are configured in the Try activity block. If the Try activity throws an exception, the exception is matched with the exception defined in the Catch activity block. If the exception matches, the steps or actions configured in the Catch activity block are executed. The Finally activity is executed irrespective of occurrence of an exception. Steps or actions in the Finally activity block are configured to be executed when either the Try activity or any required action in the Catch activity completes. If the exception does not match, the Finally activity block is not executed and the exception is passed to the parent activity.

The parent activity (an activity block, for example, an Application activity) has an option to consume the error by setting its Ignore Error property to Yes. The automation process workflow is terminated if the parent activity at the root level of the workflow does not consume the error.
