You can customize information to display to users when they run actions. Specifically, you can:
Specify whether to display a confirmation prompt to users when they execute the action.
Customize a dialog that is displayed to users when they need to supply action parameter values before the action is executed.
Customize an invocation successful message that is displayed to users, or, for an Invoke a Web Service action, you can customize a dialog to display information about the results of the action.
Customize an invocation failure message that is displayed to users.
You use the "Action Options dialog" to customize this information when you create or edit an action. See "Specifying the Settings for New Actions."
