Hi
I'm afraid you forget selecting the SSFS option during installation and it is the only connection method supported for kernel 7.40
It should be possible to fix this manually and perform all the step to connect using SSFS... but restarting your installation might be faster & easier.
1622837 - Secure connection of AS ABAP to Oracle via SSFS
As of SAP Kernel Release 7.40 (irrespective of the Oracle version), only the secure connection (secure connect) is supported via SSFS.
