I need to write a rules to allow customers to see their invoices, but I get this error
odoo.exceptions.AccessError: ('Sorry, you are not allowed to access this document. Only users with the following access level are currently allowed to do that:\n- Sales/User: Own Documents Only\n\t- Other Extra Rights/Portal\n\t- Technical Settings/Show Full Accounting Features\n\t- Inventory/User\n\t- Accounting & Finance/Billing\n\n(Document model: account.invoice.line) - (Operation: read, User: 243)', None)
How can I set the rules to give it access?
