How To Fix SR055 - User can be used for remote logon in target system

SAP Error Message - Details

• Message type: E = Error

• Message class: SR - RFC utilities

• Message number: 055

• Message text: User can be used for remote logon in target system

What causes this issue?

Logon data stored in an RFC destination is used to log on to the target
system. Since RFC destinations can be used, in principle, by each user
with RFC authorization, this logon data may represent a gap in the
system security.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Only store logon data for an RFC destination that has very restricted
authorizations in the target system. Then there is no risk when you use
RFC to access this system. If you are using a user with the type
"Service" or "Communication", then you can only communicate with the
target system of the destination from programs, and not with a dialog
(for example, for remote debugging or remote logons).

• What is the cause and solution for SAP error message SR055 - User can be used for remote logon in target system ?

  The SAP error message SR055 indicates that a user is configured to allow remote logon to a target system, which may not be the intended configuration. This message typically arises in the context of system administration and security settings within SAP environments, particularly when dealing with remote connections or system authorizations.
  Cause:
  The error message SR055 is triggered when:
  
  A user account is set up with the capability to log on remotely to a target system, which may violate security policies or best practices.
  The user may have been assigned roles or profiles that allow remote access, but this access is not desired or is restricted by the system's security settings.
  
  Solution:
  To resolve the SR055 error, you can take the following steps:
  
  
  Review User Authorizations:
  
  Check the user’s roles and authorizations in the target system. Ensure that the user does not have unnecessary remote access permissions.
  
  
  
  Modify User Settings:
  
  If the user should not have remote logon capabilities, you can modify the user settings in transaction SU01:
  
  Go to the user profile.
  Check the "Logon Data" tab.
  Ensure that the "Remote Logon" option is not enabled.
  
  
  
  
  
  Adjust Security Policies:
  
  Review your organization’s security policies regarding remote logon. If remote access is not permitted for certain users, ensure that these policies are enforced in the user profiles.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or your organization's guidelines for managing user access and security settings. This can provide insights into best practices for user management.
  
  
  
  Testing:
  
  After making changes, test the user’s access to ensure that the error message no longer appears and that the user can log in as intended.
