Confirm PTO Model is it is not priced, so its not invoiced in Oracle Fusion OM and AR

Summary:

Need confirmation that the PTO Model Item is not priced, so its not invoiced.

Content (please ensure you mask any confidential information):

But if PTO Model can be priced, then how does this ever invoice?  Does it invoice when all of the components ship?   If the components are priced/invoiced as well and shipped at different times, must all of the components ship before the Model level item is invoiced?

ATO Model is priced, however, all components need to be sourced the same way, because the top-level item is what is fulfilled on the order and invoiced.  No questions here.  Same idea for Kits.  However, with Kits, in EBS there was a BOM field "required for revenue" - - the Kit level item would invoice only when the included items enabled with this field were shipped complete.  Not sure if this is there with Oracle Cloud, and/or if there is something similar for ATO.
