Trigger EH_SAVE of Overview Page

Hello,

just a small question:

I need to trigger the EH_ONSAVE event handler of BT111H_OPPT Overview-Viewset-Controller from a view contained inside the viewset. Is there any elegant and quick way to do this in UI framework? (I don't like to directly access the hard coded class from the view controller)

Thanks and best regards,

Markus
