How can I prevent having to log on separately to the central SAP Solution Manager system in order to error messages from a satellite system?

There are two possibilities to establish a seamless trust between sending and receiving systems:

1. Establish a trusted system relationship between the sending and the central system

2. Use a general user at the RFC destination for logging on to the central system.

Note: If you use a general user at the RFC destination, there is no additional logon. However, in this case, the general user is always displayed as creator in the central system. See also SAP Note 388814 (SMP login required).

For both possibilities, the user must have the same user ID in both systems.
