RFC Trust Relationships

A calling AS ABAP can be defined in the called AS ABAP as a trusted system. The called system is then known as a trusting system. This relationships are defined in transaction SMT1

A trusted AS ABAP can log on to another AS ABAP without a password. These relationships between AS ABAP systems have the following benefits:

  • "Single sign-on" can be used across systems
  • Passwords are not transported over the network
  • Timeout mechanism for logon data prevents misuse
  • User-specific logon data for the trusted system is checked.

Other versions: 7.31 | 7.40 | 7.54
