• What is the cause and solution for SAP error message GW767 - SNC required for this connection; SNC_MODE=ON ?

  The SAP error message GW767 indicates that the connection you are trying to establish requires Secure Network Communications (SNC), but the SNC is not properly configured or enabled for that connection. The message specifically states that SNC is required for the connection and that the SNC_MODE is set to ON.
  Cause:
  
  SNC Not Configured: The SNC settings may not be configured correctly in the SAP system or the client.
  SNC Library Missing: The required SNC library may not be installed or accessible on the system.
  SNC Parameters Not Set: The necessary SNC parameters in the SAP profile or the client configuration may not be set correctly.
  Network Issues: There may be network issues preventing the proper establishment of an SNC connection.
  
  Solution:
  
  
  Check SNC Configuration:
  
  Ensure that SNC is properly configured in both the SAP system and the client. This includes checking the SNC_LIB parameter in the instance profile and ensuring that the SNC library is available.
  Verify that the SNC_MODE parameter is set correctly. If you want to disable SNC, you can set SNC_MODE=OFF, but this is not recommended if SNC is required.
  
  
  
  Install SNC Library:
  
  If the SNC library is missing, install the appropriate SNC library on the server and client machines. The library is typically provided by the SAP system or can be obtained from the SAP Service Marketplace.
  
  
  
  Set SNC Parameters:
  
  Ensure that the following parameters are set in the SAP profile:
  
  snc/enable = 1 (to enable SNC)
  snc/lib = path to the SNC library
  snc/identity/as = the SNC identity of the system
  
  
  You may also need to configure the SNC parameters on the client side.
  
  
  
  Check User Authorization:
  
  Ensure that the user has the necessary authorizations to use SNC. This may involve checking the user roles and profiles in the SAP system.
  
  
  
  Network Configuration:
  
  Check for any network issues that may be preventing the establishment of the SNC connection. Ensure that firewalls or other network security measures are not blocking the required ports.
  
  
  
  Restart SAP Services:
  
  After making changes to the configuration, restart the SAP services to apply the changes.
