I need to Create a trusted RFC between Gateway and Backend system. Because I have a combined frontend and backend system setup.
I only created in transaction SM59 an RFC connection to itself.
It should have the nameconvention: <SID>CLNT<CLIENT>.
And in the Logon & Security tab it should use the current user.
But when I create an RFC destination to the other system and make it trusting via transaction SMT1.
It show this kind of issue. I can't create successfully.
