RFC

In SAP, SM59 is a transaction code used for configuring and managing RFC (Remote Function Call) connections. RFC connections enable communication between SAP systems and external systems or applications. Within SM59, administrators can create, modify, and test RFC destinations, specifying connection parameters such as destination type, target host, system number, and login credentials. RFC connections can be used for various purposes, including data exchange, integration with non-SAP systems, and remote function calls between SAP systems. SM59 provides a central interface for managing RFC connections, ensuring secure and reliable communication between SAP and external systems.
