Stock Adjustment Cost

This module makes one small but useful change to inventory adjustments in Odoo. On the list of inventory adjustment lines, a new column called Product Cost is available. It shows the current cost of the product on that line, taken from the product's standard price.

• The column is optional, so users can show or hide it with the column selector.
• It is only visible to users with the Inventory Manager role (stock.group_stock_manager).
• The value is read directly from the product record, so it updates automatically when the product cost changes.
• It appears right after the Difference Quantity column in the inventory adjustment lines list.

The module does not add menus, buttons, reports, or automatic calculations. It only extends the existing stock.inventory.line model with a product_cost field and inherits the standard inventory line tree view to display it. No new business rules, checks, or scheduled actions are introduced.
