We have a final part that requires lets say 15 of each part A B and C.  Outside of Odoo we have 6 processes, each containing different cut configurations.  For example configuration 1 may have 1 part A and 4 part C.  Configuration 2 may have 1 part A, 1 part B and 2 part C.  This is to save material.  I understand how byproducts work and in the past I have been able to make that work if the output is unique per material sheet but in this example we have 6 different ways we need to cut up the material sheets.  I tried making variant BOM but you cant select BOM when using the component in another BOM unless maybe I set something up incorrectly.

Any help would be greatly appreciated.
