  The SAP error message LAW_MESSAGES345, which states "System already exists with a different ID," typically occurs in the context of system landscape management or when trying to register a system in the SAP Landscape Management (LaMa) tool or SAP Solution Manager. This error indicates that there is already an entry in the system landscape with the same name but a different system ID (SID).
  Cause:
  
  Duplicate System Entry: The system you are trying to register already exists in the landscape with a different SID.
  Incorrect Configuration: There may be a misconfiguration in the system landscape settings, leading to conflicts in system identification.

  Update System Configuration:
  
  If the system has been moved or its SID has changed, ensure that all configurations and references are updated accordingly in the landscape management tool.
