Is it possible to create a user that can only see and edit one product attribute?
By default, the Advanced Permissions for Magento 2 extension provides the option to allow access to the selected product attributes. This can be configured in Advanced: Product Attributes on the Role edit page:
In this case, the user will have the possibility to see and edit only one product attribute (e.g. Price):
At the moment, the extension doesn't offer the feature to restrict sections (Content, Configurations, Product Reviews, etc.) of the Product edit page. In case you require this option, please create a support request in our system; our team will advise further on the options available.
