What is an Application Class? 

Reply

An application class is an ABAP objects class that is assigned to a BSP application and contains the BSP application’s business logic.

For more information on this concept, see Application Class of a BSP Application.

The global Object application allows you to access methods and attributes of the class from any BSP.

If stateful mode is active (see Stateful and Stateless BSP Applications), the current state of the application class is maintained. If stateless mode is active, the values are reset.
