While going thru https://www.odoo.com/slides/slide/subscription-basics-697?fullscreen=1, there are fields like 

1. Automatic closing 

2. Deferred Revenue

3. Invoice and charge  and few other fields were shown but when i am logging in my enterprise edition, these fields are missing. Not only in subscription module, such problems are coming in other modules also. 

I am not able to understand why my screen are showing less function button or fields than shown in slides even though we are in enterprise edition V15. 

Please note we are on SAAS module enterprise edition.
