I am unable to test services in transaction SICF in my SAP system because I have enabled HTTPS (on port 443) and removed the HTTP port.
SICF uses the Virtual Default Host. How can I change the properties of this to make it use the HTTPS connection?
I found that I had to change the service parameter icm/server_port_0 to be the main port I wanted to use (i.e. HTTPS 443).
This isn't a nice solution, but it works and I haven't found any solution documented by SAP-AG.
