After initial authentication for a transactional app, which technology is used for subsequent OData calls?

• A. Basic Authentication
• B. OAuth 2.0
• C. ABAP Session security
• D. Kerberos authentication

Answer: (C)

The technology used for subsequent OData calls after the initial authentication in transactional apps is ABAP Session security. Once a user is authenticated, the system often maintains the session state using ABAP session management techniques. This allows the user to make multiple OData calls without needing to re-authenticate each time, as long as the session remains active. This is crucial for maintaining a smooth and seamless user experience when interacting with applications, as it avoids the overhead of repeated authentication requests. In a Fiori application context, after the user has logged in, the session state typically allows for easier and quicker access to data through OData services, which are often the backbone of Fiori’s interaction with the backend systems. Therefore, utilizing ABAP Session security ensures that the user's context and authorization are preserved across OData requests made during that session.
