Odoo is the world's easiest all-in-one management software. It includes hundreds of business apps:
CRM | e-Commerce | Accounting | Inventory | PoS | Project management | MRP | etc.
I give a access portal to my customer:
Customers>>More>>Portal Access Management and check the box In Portal.
if the customer click on the sale order to see and print it receives the error:
Access Denied The requested operation cannot be completed due to security restrictions. Please contact your system administrator. (Document type: Partner, Operation: read)
he can not print a sale order.it can print only attached documents.
