WebSocket RFC
RFC IS READY FOR INTERNET USE
WebSocket RFC uses standard HTTP infrastructure: Reverse
proxies, HTTP routers, etc. instead of proprietary SAP router
WebSocket RFC
VPN tunneling no longer needed for RFC connections across
business networks
Same CALL FUNCTION statement for RFC over WebSocket and
CPIC
Use new destination type “W” for RFC calls via WebSocket
Security: HTTPS enforced and UCON protection for WebSocket
RFC with dedicated allowlist to make Function Modules
accessible from the internet.
Limitations by WebSocket RFC: RFC callbacks
and calling function modules that open SAP GUI-based user
interfaces not supported
