Production Orders Hierarchy

When a manufacturing order triggers other manufacturing orders through multi-level bills of materials, this module links them together automatically. Each production order stores a parent order, a root order and its child orders, so you can follow the full chain from the top-level order down to the lowest components.

On the manufacturing order form, a Hierarchy button appears in the button box as soon as the order has child orders. Clicking it opens a list of all production orders sharing the same root order, grouped by root order and parent order. The form also shows the Root order and Parent order fields when they are set.

The production orders list view now includes Root order and Parent order columns, and the search filters add grouping options for Root order and Parent order.

The module touches mrp.production and stock.rule. The parent/root links are filled in automatically when Odoo creates the child manufacturing orders from procurement rules, so no manual entry is needed. Cancelled child orders are excluded from the child orders list.
