    Logoff is very simple in WD4A, as WD is just based on WEB.

    Okay, the steps you can try:

    (1).Create one outbound plug in the view.

    (2).In your button action handler, using the example code:

    wd_this->Fire_log_off_Plg( ).

    (3).create one Inbound Plug in your main window.

    (4).Create one Outbound plug in window, pls be noted,the plug type is "EXIT", and plug the "Interface" indicator

    (5).in your inbound plug's handler of your main window,using the example code:

     wd_this->Fire_exit_window_Plg( ).

    (6).In the window, navigate your outbound plug of View to the inbound plug of window.

    Best wishes.

    • hi,naveen.

      Sorry for reply late..

      About the backend functionality, i don't know how to describe or how to explain..

      However, i can say that:

      At runtime, when the action navigate to the Outbound plug of View, which linked to the inbound plug of Window, then, you again linked to the EXIT outbound of window.

      This Exit outbound plug will exit the window...

      In fact, generally, when we log out, we also should provide user that he can REALLY close the IE Browser..About how to realize it, i think you have already been very familiar with.That way, we can use the JS, as the way we treated in traditional WEB technology,such as HTML, ASP,JSP,ASPX,etc..

      Er...About the backend, i think SAP has already considered and published related theories, such as Session, Cookies..I am sorry for that, as a developer, many time i just use the existing technology/Skills, instead of not looking into the BACKEND area like you..

      Thanks you for discuss..

      Best wishes.
