Click Setup > Product Tools > Generate PO for Record below Reorder Level. Product tools are NOT under Setup

On this page
https://zohocrm.wiki.zoho.com/Creating-Products.html
it says
Click Setup > Product Tools > Generate PO for Record below Reorder Level. 

BUT
Product tools are NOT under Setup

I need to know where I can see and manage and edit all of my existing Products.

How do I do that? What is the URL?
