What is the function of the complete button in the Logistics/Inventory module?

Hello how are you?
I have a doubt with the handling of the complete button in the Inventory module (Logistics / Inventory)
Since at the time of adjusting the physical inventory with the products marked as consumables, it does not bring them to me, I would like to know what process the button completes, I would appreciate your help.

The complete button of inventory (as the help text says) adds an inventory line for each missing products.
By products we mean the goods. But we do not fill a line for the consumable because by definition consumable are goods for which we do not care about the inventory.
