To establish a relationship between the work definitions of Engine Finished Good and Pallet Finished Good, you can create a common subinventory. This subinventory will serve as the completion subinventory for the Pallet Finished Good and the supply subinventory for the Engine Finished Good. This ensures that the Pallet Finished Good is completed in one process and is then available as a component for the Engine Finished Good.
Subinventory Linking: Using a common subinventory ties the output from one work definition as an input to another. The Pallet becomes an inventory item that is consumed in the production of the Engine.
