Smart SAP Assistant

• What is the cause and solution for SAP error message GW722 - SNC required for all connections ?

  The SAP error message GW722: SNC required for all connections typically indicates that the SAP system is configured to require Secure Network Communications (SNC) for all connections, but the necessary SNC configuration is either missing or not properly set up.
  Cause:
  
  SNC Configuration Missing: The SAP system is set to require SNC, but the SNC parameters are not configured in the system.
  SNC Library Not Installed: The required SNC library (e.g., SAP Cryptographic Library) is not installed or not accessible.
  Incorrect SNC Parameters: The SNC parameters in the SAP system might be incorrectly configured, leading to connection issues.
  Client Configuration: The client trying to connect to the SAP system may not be configured to use SNC.
  
  Solution:
  
  
  Check SNC Configuration:
  
  Ensure that the SNC is properly configured in the SAP system. This includes checking the parameters in the instance profile (e.g., snc/enable, snc/identity/as).
  Use transaction RZ10 to check and modify the instance profile parameters.
  
  
  
  Install SNC Library:
  
  Make sure that the SAP Cryptographic Library is installed on the application server and is accessible. This library is necessary for SNC to function.
  
  
  
  Verify SNC Parameters:
  
  Check the SNC parameters in the SAP system. Ensure that the snc/identity/as parameter is set correctly to the appropriate SNC name.
  Ensure that the snc/accept_insecure parameter is set to 0 if you want to enforce secure connections.
  
  
  
  Client Configuration:
  
  Ensure that the client (e.g., SAP GUI) is configured to use SNC. This can be done in the SAP GUI options under the "SNC" tab.
  Make sure that the SNC name used in the client matches the SNC name configured in the SAP system.
  
  
  
  Testing the Connection:
  
  After making the necessary changes, test the connection again to see if the error persists.
  
  
  
  Related Information:
