• What is the cause and solution for SAP error message 14045 - Error; only SNC connections are allowed ?

  The SAP error message "14045: Error; only SNC connections are allowed" typically indicates that the system is configured to require Secure Network Communications (SNC) for connections, but the current connection attempt is not using SNC. This can occur in environments where security policies mandate the use of SNC for data encryption and secure communication between SAP systems.
  Cause:
  
  SNC Configuration: The SAP system is configured to enforce SNC connections, but the client or application trying to connect is not set up to use SNC.
  Incorrect Connection Parameters: The connection parameters used in the client application may not specify the use of SNC.
  SNC Library Issues: There may be issues with the SNC library or its configuration on the client side.
  User Profile Settings: The user profile may have settings that require SNC connections.
  
  Solution:
  
  
  Check SNC Configuration:
  
  Ensure that the SAP system is correctly configured to use SNC. This includes checking the SNC parameters in the SAP profile (e.g., snc/enable should be set to 1).
  Verify that the SNC library is correctly installed and configured on both the server and client sides.
  
  
  
  Use SNC Connection:
  
  Modify the connection settings in the client application to use SNC. This typically involves specifying the SNC name in the connection string.
  For example, in SAP GUI, you can specify the SNC name in the connection properties.
  
  
  
  Update Client Application:
  
  Ensure that the client application is capable of establishing SNC connections. This may involve updating the application or its configuration.
  
  
  
  User Profile Settings:
  
  Check the user profile settings in the SAP system to ensure that the user is allowed to connect using SNC. You can do this by checking the user’s parameters in transaction SU01.
  
  
  
  Testing:
  
  After making the necessary changes, test the connection again to ensure that it is successful.
  
  
  
  Related Information:
  
  SNC Documentation: Refer to the SAP documentation on SNC for detailed configuration steps and requirements.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues or provide additional guidance related to SNC connections.
  Security Policies: Review your organization’s security policies regarding the use of SNC to ensure compliance.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis team or reach out to SAP support for further assistance.
