What is SICF?

SICF stands for Service Interface Configuration Framework. In the context of SAP systems, SICF is a framework used for configuring and managing internet communication framework services (ICF services). These services enable communication between SAP systems and external applications or systems via protocols like HTTP, HTTPS, and others. SICF provides tools and transactions for activating, deactivating, configuring security settings (like authentication and authorization), and monitoring ICF services. It is crucial for scenarios involving web services, OData services, and other forms of external communication with an SAP system.
