In SAP systems, users with system administration authorization have access to additional functions in the SAP Easy Access menu to manage system security and user administration. The menu includes options for creating roles, allowing administrators to use transaction PFCG to define and maintain authorization roles, which are critical for assigning permissions to users based on their job functions. Additionally, the menu provides access to creating users, enabling administrators to use transaction SU01 to set up user master records, including user IDs, passwords, and role assignments. These functions are essential for managing access control and ensuring system security. Calling menus for roles and assigning them to users is not a specific function of the Easy Access menu, as role assignment is typically performed within SU01 or PFCG. Calling programs is a general user function, not exclusive to administrators. These administrative capabilities in the Easy Access menu streamline security management tasks in SAP environments.
