Which assignments are recommended in SAP HANA?

In SAP HANA, it is recommended to assign roles to roles as this approach allows for a more organized and scalable system of permission management. By creating hierarchical relationships between roles, you can simplify user management and ensure that permissions are inherited in a way that aligns with the business structure and security requirements of the organization.

This method allows administrators to define a core role that includes a set of privileges, and then create more specific roles that inherit those privileges as needed. It reduces repetition since permissions do not have to be assigned individually to each user or role, and promotes easier maintenance as adjustments to privileges can be managed at the role level instead of at multiple user levels.

Assigning roles to users directly is also common but can lead to a situation where managing multiple individual assignments becomes cumbersome and less controlled. In contrast, assigning privileges directly to users lacks the structured approach that roles can provide, and merely linking privileges to roles doesn’t harness the advantage of role hierarchies which can encapsulate permission management more efficiently.

Overall, by promoting a structured approach through role-to-role assignments, SAP HANA fosters greater flexibility, ease of management, and adherence to security best practices.
