This module introduces a constraint to ensure that a contact cannot simultaneously be both a customer and a supplier.
auto_awesome What this module does
AI-generated from the code · Odoo 18.0Prevents a contact from being both a customer and a supplier at the same time. When a contact already has a customer or supplier rank, the opposite rank is not increased.
This module adds a rule to contacts (res.partner) so that a single contact cannot be both a customer and a supplier. If someone tries to save a contact that has both a customer rank and a supplier rank greater than zero, Odoo blocks the save and shows the error message: "A contact cannot be both a customer and a supplier."
It also changes how ranks are increased automatically. When Odoo would normally increase the customer rank for a contact that already has a supplier rank, or increase the supplier rank for a contact that already has a customer rank, the increase is skipped. This means a contact keeps only one role: either customer or supplier, not both.
The rule applies everywhere contacts are created or edited, including sales and purchase documents that update ranks in the background. There are no new menus or screens; the change is a validation and automatic behaviour on the existing contact form and related processes.
