      • The problem is if you have different system aliases for the same system/RFC connection. In a HUB deployment scenario it is completely fine to operate My Inbox with multiple back-ends.
      • I ran into a problem recently where I used role-based system alias determination. When users had multiple roles which granted access to a specific system alias - IMO which is a completely valid use-case - the experienced this behavior. I ended up using the BAdI mentioned in this blog to remove duplicated entries.
