Akeneo Enterprise Edition supports access control in the user interface of the system. However, there is no native access control for the exported or imported data. This bundle adds the access control (users can only export/import data they have access to) and extra features including limitation of import of the products not assigned to any categories and partial import.
This extension is compatible with Community and Enterprise Editions.
