# Create Webservice RFC Destination

This RFC destination is the web service that connects to the TCT portal service to activate the plant. When calling a function module using the RFC interface, the calling program must specify the parameters of the connection in the form of a destination. This destination defines the type of connection, the parameter program and the target system.

:information\_source: The SAP system will require external internet access directly or via a proxy in order to use the web service. The license will only need to be activated once per plant, this can then be moved through your SAP landscape via transports.

Navigate to transaction SM59. Select option ‘HTTP Connections to External Server’, select the create button
