Click the "User Permissions" tab on any User Details page to view that user's applied Product Restrictions.

1. "User Groups" shows which User Groups this user is a member of (because either their username or Customer Code is part of the group).
2. "All Product Restriction Groups" shows the Database ID of all Product Restriction rules that are applied to the user.
3. The applied permissions are also shown to help aid in understanding which items are visible to this user.
