A user navigates within a portal to an iView.
I have a requirement to add a button onto the iView WD application that
would simply close the iView which was opened.
I understand that in the portal we cannot use an exit plug.
Instead we simply add an outbound plug to the WD view which
accepts a single parameter close_window of type wdy_boolean.
I fire this plug in the button, passing close_window = abap_true,
but the view stays open.
