Definition

This switch specifies whether a Web Dynpro application is run as a stateful (recommended) or stateless application.

Use

  • Stateful: When the application URL is first called, a new ABAP session is created. The ABAP sesson stays open until the application is closed. This is the recommended operation mode for Web Dynpro applications.
  • Stateless: With each call a new ABAP session is created, which is closed immediately after the result is sent. Accordingly, with each request the Web Dynpro ABAP application and its components are reopened, and then closed again.

    In stateless operation some Web Dynpro ABAP functions cannot be used. For more information, see the SAP documentation "Web Dynpro ABAP -> Developing Stateless Applications".
