- We refactored the VAT validation from a validation error to a warning that is stored in l10n_ec_vat_error - Remove the "-" and "EC" from the base_vat in the EC validation/example - Only validate the length in the base_vat - Add compute field with the warning message in the l10n_ec closes odoo/odoo#123708 X-original-commit: 19b9384867485ea5fc30bac9192a21a91335f567 Signed-off-by: Josse Colpaert <jco@odoo.com>
