Partner Identification EORI

This module extends the partner identification numbers feature by adding a ready-made category called "EORI Identification Number" (internal code eori_id_number). You can select this category when adding an identification number to a contact (res.partner), for example on a customer, supplier or company record.

When an EORI number is saved, Odoo runs a validation rule attached to that category:

• If the number is empty, no check is done.
• If the partner has a country and the number does not start with that country's two-letter code, the validation is skipped (returns no error).
• Otherwise, Odoo checks whether the same EORI number already exists for another partner and blocks duplicates.

The module does not add new menus or screens of its own; the new category appears wherever partner identification numbers are managed, inside the contact form. It touches the res.partner.id_category model by adding the validation method validate_res_partner_eori, and it relies on the existing duplicate-check logic of the partner identification module. No scheduled jobs, emails or reports are added.
