Odoo is the world's easiest all-in-one management software. It includes hundreds of business apps:
CRM | e-Commerce | Accounting | Inventory | PoS | Project management | MRP | etc.
Thanks for you answer. I managed to make the value unique by inheriting the product module. This page explains how to write a costum module http://www.pixelite.co.nz/article/adding-additional-fields-using-custom-module-openerp-7.
Here the python file (if someone wants to do the same):
from openerp.osv import fields, osv
_inherit = "product.product"
_sql_constraints = [
('uniq_defaut_code', 'unique(default_code)', "A external reference already exists with this name . External reference must be unique!"),
You need to add some custom code, inheriting the product module and adding a constraint to the field. That will make it unique, even with a small message telling the user their input should be unique.
By default I don't think there is any module that does this for you, although I would be happy to proven wrong.
