Stock Move Line Qty Picked

This module separates the quantity that is actually picked from the reserved quantity on stock move lines. In Odoo, the 'Quantity' field on a move line represents the reserved quantity. Changing it can alter reservations. With this module, a new 'Quantity Picked' field is added, so users can enter the real picked quantity without touching the reservation.

A 'Picked' checkbox is also added. When a user enters a picked quantity, the line is automatically marked as picked. If the picked quantity is greater than the reserved quantity and there is enough demand, the reserved quantity is automatically increased to match the picked quantity. When the transfer is validated, the reserved quantity is updated to the picked quantity for all picked lines.

The new field appears in several places: in the detailed operations list (hidden by default), in the move line form, and in the operations tab of the transfer form. It is also available on the stock move itself as a computed field that sums the picked quantities of its lines.

This module is useful for warehouses that use barcode scanners or need to record actual picked quantities without modifying reservations. It works with the standard Inventory app and affects stock moves, move lines, and transfers.
