What feature do you use to specify which users are able to access a Service Catalog Item?

User Criteria is the designated ServiceNow feature for controlling access to Service Catalog items and categories. It allows administrators to define reusable sets of conditions based on a user's attributes, such as their roles, group memberships, department, or location. These criteria are then applied to a catalog item through the "Available For" and "Not Available For" related lists to grant or deny visibility and the ability to order the item. This provides a flexible and powerful method for managing catalog item entitlements without creating complex ACLs.

A. Can Read Role: This is not a standard ServiceNow feature. Access is managed by User Criteria, which can be based on roles, but not a specific "Can Read Role".
B. Catalog User Role: The catalog role grants general access to the Service Catalog application but does not control the visibility of specific, individual items.
C. Can Order Tab: This is a UI element on the catalog item form where ordering options are configured, not the mechanism for controlling user access to the item itself.

2. ServiceNow Product Documentation: "Create or edit a catalog item". In the section describing the catalog item form, it details the "Available For" and "Not Available For" related lists, which are used to "Add or remove user criteria records to control access to a catalog item."
