Hi Odoo experts,

I would like to receive alert when a product expired. I see in the demo, the product have fields such as end of life date, alert date, best use before date...

I set it with some value but, I don;t know how to active this function.

I think I should add this module: https://www.odoo.com/apps/modules/online/product_expiry/

Is it correct? 

How do I make additional configuration to make it work or need implement something ?

Pls give some hint for what I need to do. Thanks a lot.
