Go to Kentico CMS Desk -> Tools -> E- commerce -> Configuration -> Departments. Department is used for organization of your product management efforts - you can specify users who can manage products in the given department. It means you can have a different product manager for e.g. books and for electronics departments.
Please note that the departments are not the same as product categories displayed to site visitors.
You can create either only single department and place all products in it or you can create separate departments if you have several product managers.
Every department has these properties:
•Department display name - friendly name displayed to users
•Department code name - code name used by developers in the code
•Default tax class for new products - the tax class that is automatically assigned to the products created in the given department
In the Users tab, you can specify the users who can manage products in these departments.
