SAP Basis & More: Generate RFC Connections in Solution Manager

RFC connections to the managed systems are a prerequisite for the following Solution Manager functions:

Generate Project IMGs in the Project Administration
Go to the managed systems in the Configuration phase
Customizing Synchronization (Synchronization Group Editor, Customizing Scout, Customizing Distribution)
Read system data via the Service Data Control Center
Managing Business Function Sets and Business Functions in the Switch Framework Cockpit
Monitor change requests (Change Request Management)

You can only generate RFC connections for ABAP-based main instances.

Prerequisites

You are in the Solution Manager System Landscape transaction (SMSY), and have saved your last change.

The system for which you want to generate RFC destinations is not flagged as Planned.

Procedure

Choose the ABAP-based product instance of the system for which you want to generate RFC connections, in the left-hand frame.
Go to change mode.
Select a client in the Clients tab.

Note : You can also generate RFC destinations using an assistant. To call the assistant, choose Generate RFC with Assistant in the Clients tab. Or proceed from 4).
Choose Generate RFC Destinations.
Choose the types of the RFC connections in the following dialog box.

Recommendation

Choose the RFC connection type Trusted System for the SAP Solution Manager, whenever possible. This avoids having to logon again every time that you go to a managed system when using the SAP Solution Manager.

End of the recommendation.

The details of the RFC connection to be generated, are shown at the bottom of the screen.
Choose the user options. If, for example, you use the central user management, you can assign existing users in the managed system.
You can specify a server group for load sharing, in the RFC Destination Attributes group box.
If the specification of the message server is not sufficient to set-up an RFC connection in your network, or your network contains routers:
1. Choose Routing Information in the RFC Destination Attributes group box. The following dialog box displays the message server data. If you have not yet created the system message server as a server, it is created automatically and displayed at the left-hand side under Landscape Components, when you restart the Solution Manager System Landscape transaction.
2. You can specify an IP address.
3. Specify the routing information for the direction Solution Manager -> Router -> Server, e.g. /H/1.2.3.4/H/5.6.7.8/H/9.10.11.12
4. Specify the routing information for the direction Server -> Router -> Solution Manager, e.g. /H/5.6.7.8/H/1.2.3.4/H/20.21.22.23
  Note : The Solution Manager System Landscape calls information to generate RFC connections in the following sequence:
  Detailed routing information (e.g. /H/1.2.3.4/H/5.6.7.8/)
  
  If there is none:
  
  Server IP address
  
  If there is none:
  
  Server name
5. Save your entries.
Remote read is the default for system data, because the SAP Solution Manager requires current system data, for example, to read the data of imported Support Packages. You should not reset the flag in the Actions after Generation group box.
Set the Assign RFC Dest. for System Monitoring flag, to be able to use the RFC destinations which you generate in the Solution Manager System Landscape, in the central system monitoring (transaction RZ21), and in the SAP Solution Manager for operational processing, in your solution landscape. You only need to set this flag for one client per ABAP system.

The system enters the RFC destination data in the overview of the monitored remote SAP systems, in central System Monitoring (transaction RZ21) Techn. Infrastruktur Display Topology .
Choose Generate RFC Destinations.

You go to logon screens for each of the managed systems involved, consecutively, depending on the connection type selected.
Logon to the systems.

Note : The system generates a log with information about the checks made, and all messages sent while making the connection.
