  Transport Layer Issues: If the logical system is part of a transport layer, there may be issues with the transport configuration.
  
  
  Authorization Issues: The user executing the transaction may not have the necessary authorizations to access the logical system or the RFC destination.
  
  
  Network Issues: There may be network connectivity issues preventing the system from reaching the specified logical system.
  
  
  Solution
  To resolve the error, you can take the following steps:
  
  
  Check Logical System Configuration:

  Test Connectivity:
  
  Use transaction SM59 to test the connection to the RFC destination. This can help identify any network issues or misconfigurations.
  
  
  
  Check System Logs:
