Can I enforce unique Account Numbers (Internal Reference) for Customers and Vendors?
We have Account Numbers assigned to every Customer and Vendor, and this happens during onboarding (outside Odoo).
We are finding users entering Customers and/or Vendors into Odoo when they are already there - they are not checking properly before adding the information.
How can we build a check into Odoo so that the same Customer and/or Vendor doesn't get created more than once.
Customer Account Numbers start with "C" and Vendor Account Numbers start with "S".
