  The SAP error message R3002, which states "Target system & is not known in the source system," typically occurs in the context of system landscape configurations, particularly when dealing with system connections in SAP Landscape Management (LaMa) or when using tools like SAP Solution Manager.
  Cause:
  
  Missing Configuration: The target system is not properly configured in the source system. This could mean that the target system has not been added to the system landscape or is not recognized due to configuration issues.
  Incorrect System Alias: The system alias or the name used to refer to the target system may be incorrect or not matching the expected naming conventions.
  Network Issues: There may be network connectivity issues preventing the source system from recognizing the target system.
  Authorization Issues: The user executing the transaction may not have the necessary authorizations to access the target system.
  
  Solution:
  
  
  Check System Configuration:
  
  Go to the transaction SICF and ensure that the target system is correctly defined in the source system.
  Use transaction SM59 to check the RFC connections. Ensure that the target system is listed and that the connection is working properly.
