• What is the cause and solution for SAP error message /SMB/CUSTOMIZING074 - Connection to target system &1 is not trusted ?

  The SAP error message /SMB/CUSTOMIZING074 Connection to target system &1 is not trusted typically indicates that there is an issue with the trust relationship between the source and target systems in a landscape, particularly when dealing with system connections in SAP Business One or SAP NetWeaver environments.
  Cause:
  
  Missing Trust Configuration: The target system is not configured to trust the source system. This can happen if the systems are not properly set up for secure communication.
  Incorrect RFC Destination: The RFC (Remote Function Call) destination may not be correctly configured, or the credentials used for the connection may not have the necessary permissions.
  Network Issues: There may be network issues preventing the systems from communicating securely.
  Certificate Issues: If SSL is being used, there may be issues with the certificates that are supposed to establish a secure connection.
  
  Solution:
  
  
  Check Trust Configuration:
  
  Ensure that the target system is configured to trust the source system. This can involve setting up the necessary trust relationships in the SAP system settings.
  Use transaction SM59 to check the RFC destination settings. Ensure that the target system is listed and configured correctly.
  
  
  
  Verify RFC Destination:
  
  Go to transaction SM59 and check the configuration of the RFC destination that connects to the target system.
  Ensure that the connection type is correct (e.g., TCP/IP) and that the logon credentials are valid.
  
  
  
  Network Configuration:
  
  Check for any network issues that might be preventing the systems from communicating. This includes firewall settings, VPN configurations, or any other network security measures that might block the connection.
  
  
  
  SSL Configuration:
  
  If SSL is being used, ensure that the SSL certificates are correctly installed and configured on both systems.
  You may need to import the necessary certificates into the SAP Trust Store using transaction STRUST.
  
  
  
  Authorization Check:
  
  Ensure that the user credentials used for the connection have the necessary authorizations to access the target system.
  
  
  
  System Logs:
  
  Check the system logs for any additional error messages that might provide more context about the issue. You can use transaction SM21 to view the system log.
