Hi,

I am playing around with the community edition to get to know Odoo.

I found some doc here: https://www.odoo.com/documentation/user/9.0/sales/invoicing/services/support.html

but for some reason i get stuck in the beginning

What i want to achieve:

sell a service contract eg: 8 hours of service, client can oder, client needs to be created upon ordering, gets invoice, project needs to made and then timesheets

In the first part of the doc they talk about activating  Unit of Measures  which i did but then i need to select "some products may be sold/purchased in different unit of measure (advanced)" which i do not find.

Can anyone point me to this? Where to select this. Can this be achieved with the community edition?

Thanks

Roger
