What is the primary function of the AUTHORITY-CHECK statement in ABAP?

The AUTHORITY-CHECK statement in ABAP is primarily used to check user access rights. This statement evaluates whether the currently logged-in user has the appropriate authorizations to perform a specific action or to access particular data within the SAP system. It ensures that users operate within their allowed functions, which is crucial for maintaining security and proper access control in applications.

When used in a program, AUTHORITY-CHECK assesses the user's profile against the specified authorization objects, which are defined in the system. If authorization is granted, the program proceeds; otherwise, it typically provides feedback or restricts further actions, enhancing the overall security posture of the application.

This mechanism is vital for organizations to protect sensitive data and functionality from unauthorized access, thereby supporting compliance with internal and external regulations. Other options mention functions like granting user permissions or validating data integrity, but they do not specifically pertain to the core function of checking user access rights as defined by the AUTHORITY-CHECK statement.
