What is a key consideration when configuring a customer portal for millions of users?

When configuring a customer portal for millions of users, it's crucial to understand how users relate to the organizational data structure and the access they have. The correct consideration here focuses on the fact that users in a large customer portal environment often do not have direct associations with a rule in the hierarchy.

In large-scale implementations, especially with millions of users, it is important to maintain a scalable and manageable data access strategy. Defining hierarchy rules can become complex and may not be practical for every user, particularly if they aren't involved in the organizational hierarchy in a traditional sense. This ensures that users can have access to necessary features and data without being tied to a specific role or position in a potentially oversized hierarchy.

This context highlights the ability to configure the customer portal in a way that meets the needs of a vast user base without the constraints or complications that a hierarchical rule might impose. It also enables flexibility in managing user permissions and access controls, which is vital in large-scale portal environments.
