Stock Inventory Theoretical Quantity History

When you adjust stock through an inventory, Odoo normally only keeps the final corrected quantity. This module adds two extra pieces of information to the stock movement line created by that adjustment: the theoretical quantity (what the system believed was in stock just before the count) and the real quantity (what was actually counted).

These two values are filled in automatically when the inventory adjustment movement is generated, based on the quantity and the counted quantity of the stock quant being adjusted. They are read-only, so they cannot be changed by hand afterwards.

You can see them on the stock move line screen: in the form view they appear as "Theoretical Quantity" and "Real Quantity" next to the unit of measure, and in the list view they are available as optional columns that you can show or hide.

The module only touches stock move lines and stock quants. It does not add new menus, reports or scheduled actions; it simply enriches the existing inventory movement records with the before/after quantities for traceability.
