Product Category Code Unique
This module allows to restrict unique codes on product categories. If no code is provided, a code is generated by a sequence.
auto_awesome What this module does
AI-generated from the code · Odoo 17.0Makes the code field on product categories unique and automatically fills it with a generated sequence number when left empty, so every category always has a distinct code.
This module adds a uniqueness rule to the code of product categories, so two categories can no longer share the same code. If you try to save a duplicate code, Odoo blocks the save with the message "The category code must be unique!".
It also removes the need to type a code by hand. When you create a new product category and leave the code empty (or set it to "/"), Odoo automatically assigns the next number from a dedicated sequence called "Product Category", formatted with the prefix "PC/" and four digits (for example PC/0001). The same automatic filling happens when you edit an existing category and clear its code.
During installation, existing categories that had no code or the default "/" are given a code built from their name and identifier, so the installation does not fail on demo or legacy data.
Everything happens on the product category screen (the product.category model) that you reach from the Products area. No new menus or reports are added; the change is a business rule applied when categories are created or updated.
