Hi, I am a newbie developer for Odoo.

I added a user and tried create a product in Sales/Inventory/Purchase.

The user has Sales/Manager access rights.

But I got a error message following in any apps:

Error while validating constraint

The requested operation cannot be completed due to security restrictions. Please contact your system administrator.

(Document type: product.template, Operation: read)
None

I've used version 9. But it happens on online version too.

What I can do to solve this problem?

Please help me...
