Steps to reproduce the bug: - Go to Inventory→ Configuration→ Warehouse Management →Operations Types - Go inside “Manufacturing”, and disable the checkbox “Create New Lots/Serial Numbers for Components” under the traceability section - create a MO with a traceable component - Confirm the MO Problem: You can create a new SN for the component without any warning, while the user is supposed to be blocked by a user error: https://github.com/odoo/odoo/blob/master/addons/mrp/models/stock_lot.py#L11-L16 The solution: We need to add the `active_mo_id` key in the context so that the user error will be triggered opw-2900256 closes odoo/odoo#96648 X-original-commit: 6d0ddc388d1c389e1911a6bb1c59c252870da1a7 Signed-off-by: Arnold Moyaux (arm) <arm@odoo.com> Signed-off-by: Djamel Touati (otd) <otd@odoo.com>
