Understanding the Application Stack Option in a Form Request

Use the Application Stack option to create a form request that establishes a session for a specific application and maintains that session across calls. With application stack processing, the form request can invoke multiple forms in different applications to complete a business process. Without application stack processing, each form in a form request is opened independently.

If you use the Application Stack option, the form request must include instructions for navigating between forms. Without the navigation, additional forms cannot be called.

Only values from the last form in the application stack can be returned; return controls specified for any form except the last form are ignored.
