List of Trusted RFC return codes


The purpose of this document is to list the error codes that can be returned during a trusted RFC connection, including the meaning of each return code.


A trusted RFC was configured between two ABAP systems.

However, something is not correct at this setup, causing an error while such trusted connection is being used.

Such error is usually observed at a "CALL_FUNCTION_SINGLE_LOGIN_REJ" dump (transaction ST22).


Fix the incorrect settings related to the trusted setup.

Knowing the meaning of the return codes can help identifying what needs to be fixed.

  • The possible return codes for the "trusted system" (T-RC) are:

0 Correct logon via trusted system.
1 No trusted system entry for the caller system "<SID> " with the installation number " ", if this exists, or the security key entry for system "<SID> " is invalid.
2 User "<user ID> " does not have RFC authorization (authorization object (S_RFCACL) for user "<user ID> " with client <client>.
3 The time stamp of the logon data was invalid.

  • The possible return codes for the "logon procedure" (L-RC) are:

0 USER_OKLogin was correct
1 USER_NOT_ALLOWEDUser or password incorrect
