I sort of asked the same here: https://forums.novell.com/showthread...cting-from-SAP but I got no response.

There are in the SAP documentation notes on how to create an account with privileges for a JCO RFC connection. If I recall correctly there is a built-in account which you could use or, even better, create a different system account and copy the roles from the built-in account to this new user.

I would link you to the official SAP documentation but I no longer have access to it.
