Stock Avaiable Stock Mts Mto Rule

This module is a technical bridge between two other modules: one that adds an "immediately usable quantity" indicator on products, and one that splits procurement between make-to-stock and make-to-order based on available stock.

With this module installed, the MTS/MTO rule no longer looks at the forecasted (virtual) quantity when deciding whether a product should be taken from stock or made/purchased to order. Instead it uses the immediately usable quantity, which only counts stock that is physically on hand and not already reserved.

• The rule is applied automatically whenever Odoo evaluates a stock rule for a product; users do not configure anything extra.
• It affects the stock.rule model, which is the engine behind routes and procurement rules in Inventory.
• No new menus, screens, buttons or reports are added; the change is invisible in the interface but changes the resulting procurement decisions.

Because the module is marked as hidden and contains no user-facing configuration, its effect is only visible indirectly: orders may be split differently between stock and make-to-order when some on-hand stock is reserved or otherwise not immediately usable.
