RFC Trust Relationships

A calling AS ABAP can be defined as a trusted system in an AS ABAP to be called. The called system is then termed a trusting system. You maintain these trust relationships using transaction SMT1.

A trusted AS ABAP can log on to another AS ABAP without a password. This kind of trust relationship between AS ABAPs has the following advantages:

  • "Single sign-on" can be used across systems.
  • No passwords are transferred across the network.
  • Timeout mechanisms for logon data prevent misuse.
  • User-specific logon data for the calling system is checked.

Other versions: 7.31 | 7.40 | 7.54
