While DEFINING RFC destination via TCODE SM59, there is an option to make the RFC connection as 'Trusted'. Once selected, the calling (trusted) system doesn't require a password to connect with target (trusting) system.

Following are some of the advantages of using trusted channels:

• Cross-system Single Sign-On facility.
• Password does not need to be sent ACROSS the network.
• Timeout mechanism for the log-on data prevents MISUSE.
• Prevents the mishandling of log-on data because of the time-out mechanism.
• User-specific log-on details of the calling/trusted system is checked.

The RFC users must have the required authorizations in the trusting system (AUTHORIZATION object S_RFCACL).Trusted connections are mostly used to connect SAP Solution Manager Systems with other SAP systems.
