I am creating a payment through the action_create_payments method in Odoo online with Python but I need to add a value to the payment_reference field but I think it is not possible without changing the source code, so I am trying to edit it once created but I get the following error <Fault 2: 'You cannot modify the following read-only fields in a published transaction: partner_id, currency_id, partner_bank_id, line_ids'>. How could I edit it? Regards
