Stock Move Line Serial Unique
This module adds a constraint on stock.move.line to make sure that no stock exists for the specified serial 1) when serial is input (in lot_name field), and 2) when the lot is being created (in _action_done()) in purchase receipts, to avoid duplicates.
Standard behavior fails to prevent the duplicates, for example, when there is stock for a serial with no owner, and new stock comes in with the same serial with an owner. This module intends to cater to this case.
auto_awesome What this module does
AI-generated from the code · Odoo 16.0Prevents duplicate serial numbers from being entered or created on stock moves, blocking receipts or manufacturing orders when the same serial already exists in stock.
This module adds a validation rule to stock move lines so that a serial number cannot be used twice. It applies when a product is tracked by serial number and the operation type allows creating new lots.
- When a user types a serial number in the lot/serial field on a receipt or manufacturing order, Odoo checks whether that serial already exists for the same product and company. If it does, the entry is blocked with an error message.
- The same check runs when a new serial record is being created during the validation of the transfer, so duplicates cannot slip through at that stage either.
- The check uses the existing serial-number verification logic from stock quants, which means it also catches cases where the existing stock has no owner but the new one does.
The rule is enforced on stock.move.line and relies on the product's tracking setting and the operation type's lot-creation option. No new menus, fields, or reports are added; the change is purely a safety constraint on data entry and transfer validation.
