• What is the cause and solution for SAP error message SNC769 - SNC name for RFC/CPIC does not exist in any ACL ?

  The SAP error message SNC769 indicates that the Secure Network Communications (SNC) name for the Remote Function Call (RFC) or Common Programming Interface Communication (CPIC) does not exist in any Access Control List (ACL). This typically occurs in environments where SNC is configured for secure communication between SAP systems or between an SAP system and external systems.
  Cause:
  
  Missing ACL Entry: The SNC name used for the RFC/CPIC connection is not defined in the ACL. This means that the system does not recognize the SNC name as an authorized entity for communication.
  Incorrect SNC Name: The SNC name specified in the configuration might be incorrect or misspelled.
  SNC Configuration Issues: There may be issues with the overall SNC configuration, such as missing or misconfigured parameters in the SAP system or the external system.
  Authorization Issues: The user or service account being used for the connection may not have the necessary permissions to access the specified SNC name.
  
  Solution:
  
  
  Check ACL Configuration:
  
  Go to transaction SNC0 in the SAP GUI.
  Verify that the SNC name used for the RFC/CPIC connection is listed in the ACL.
  If it is not present, add the SNC name to the ACL with the appropriate permissions.
  
  
  
  Verify SNC Name:
  
  Ensure that the SNC name configured in the RFC destination (transaction SM59) matches the name defined in the ACL.
  Check for any typographical errors or discrepancies.
  
  
  
  Review SNC Parameters:
  
  Check the SNC parameters in the SAP system (e.g., snc/enable, snc/identity, snc/acl) to ensure they are correctly set.
  Ensure that the SNC library is correctly installed and configured on the SAP system.
  
  
  
  User Authorization:
  
  Ensure that the user or service account being used for the connection has the necessary authorizations to access the SNC name.
  Check the roles and profiles assigned to the user to ensure they include the necessary permissions.
  
  
  
  Testing:
  
  After making changes, test the RFC connection again to see if the error persists.
  Use transaction SM59 to test the connection and check for any additional error messages.
