What is the purpose of the @AccessControl annotation in a CDS view?

The purpose of the @AccessControl annotation in a CDS view is to define access rules for the data presented in that view. This annotation plays a crucial role in enforcing security by specifying which user roles or authorizations are required to read, create, update, or delete data exposed by the CDS view. By using this annotation, developers can ensure that sensitive data is adequately protected and that only authorized users can perform certain actions on the data, thereby facilitating a structured approach to data access management.

This enables more granular control over data visibility and manipulation within SAP applications and is essential for compliance with data governance and security policies. The use of this annotation helps support a secure data access strategy directly within the data model, enhancing the overall integrity of applications built on this modeling paradigm.
