Stock Picking Show Backorder

This module makes backorders visible directly from the original transfer in Odoo's Inventory app.

On the transfer form (the screen used for receipts, deliveries and internal transfers), a new "Backorders" tab appears in the notebook section. It lists every transfer that was created as a backorder of the one you are viewing. The tab is hidden automatically when there are no backorders, so it only shows up when it is useful.

The list is read-only: it is a display of related transfers, not something you edit by hand. Each backorder is linked to its parent transfer through the standard backorder relationship already used by Odoo's stock module, so the list stays up to date as new backorders are generated when a transfer is only partially processed.

No new menus, buttons, reports, checks, emails or scheduled actions are added. The module only extends the existing stock.picking model with a backorder_ids field and inherits the standard transfer form view to show it. It depends on the Inventory (stock) module and does not change how backorders are created or processed.
