Enhancements to existing features
This update adjusts how Odoo handles tax exemption reasons on UBL invoices. Previously, a specific reason was always required, but now it's optional. When a reason isn't provided, a default reason is automatically applied based on the tax category, ensuring compliance with UBL standards.
Original PR description
According to the ubl documentation the tax exemption reason code is not always required on the document. But when no exemption reason code is given, we have a default exemption reason for the appropriate tax categories. task: 5223145 Forward-Port-Of: odoo/odoo#233770
