I have two questions:
1) Can I deactivate/delete system views? If yes then how?
2) I have a view "Open opportunities" that lists all the opportunities and a view "Won opportunities" that has the opportunities that have been won. I want to know that is there a way that an opportunity automatically gets removed from open opportunities once it has been won? Currently it is present in both the lists open & won. I want it to get removed from open opportunities and be only visible in Won opportunities view.
