Hi Alec, please find the in-line answers to your queries below:

1. If I want to use Three-Step Manufacturing and have that checked as a route, would the Manufacture route still need to be checked?

• Yes. The "Manufacture" route tells Odoo that the product is made in-house. The "Three-Step Manufacturing" route just changes how the product moves in the warehouse
  

  So, both routes must be enabled on the product for the three-step process to work.

2. If I have subassemblies 1, 2, and 3 that are sub-boms to make a finished product using a manufactured BoM, would a route still need to be placed on those subassemblies if I have the route set on the top level finished product?

•  Yes. If your finished product is made from subassemblies, you need to set the "Manufacture" route on each subassembly. Odoo does not copy the route from the final product to its parts — you must set it for each one.

3. If I'm using Kit BoMs, the type that isn't manufactured, If I have manufactured finished product BoMs within a Kit, what route should be used? Would I need to add a 4th step that updates kit product quantities from the 3rd after storing finished goods?

•  A Kit BoM means the product is not manufactured, it's just a group of items picked together during delivery.
  
•  Set the "Manufacture" route on that product
  
•  Make sure it's already made and available in stock before delivering the kit
  
•  Odoo does not update kit quantities when components are made — because kits are just virtual.
