Hello Expert,
I am preparing for a setup and I would like a point of documentation to be clarify, if anyone can, i will appreciate.
In the CTE_SETUP, no matter if you select Direct or Middleware, the RFC is required field. In the documentation it is said to create an RFC using TCode SM59, but it is not mentioned anywhere what to enter in the RFC?

1. Should we use the Concur Host "www.concursolutions.com" as Host and Port '443' for the RFC?
2. In the logon tab, what to use as login? and Certificate?
3. For a Middleware setup, why the RFC is still required when there is already the Middleware Host and Path Prefix required?
