Short Text
 You are not authorized to logon to the target system (error code 1002).

Error analysis
 RFC calls (Remote Function Calls) were sent with invalid user ID "SM_<SID>".
 The receiving system treated the first call as a system call and therefore accepted it without a valid user ID. The last call was sent to a non-system function module however and was therefore rejected.
 The system function modules include RFC_PING and RFC_SYSTEM_INFO.
 The action was executed by caller "SM_<SID> " with client <CLI> from system "<SID> " using transaction " ".
