• What is the cause and solution for SAP error message 00779 - Could not find a suitable SAP user for the SNC name of the caller ?

  The SAP error message "00779 Could not find a suitable SAP user for the SNC name of the caller" typically occurs in the context of Secure Network Communications (SNC) when the system is unable to map the SNC name of the user to a valid SAP user account. This can happen in environments where SNC is configured for secure communication between SAP systems and clients.
  Causes:
  
  SNC Configuration Issues: The SNC configuration may not be set up correctly, leading to mismatches between the SNC name and the SAP user.
  Missing User Mapping: The SNC name of the caller does not have a corresponding SAP user in the system.
  User Lock or Deactivation: The SAP user that corresponds to the SNC name may be locked or deactivated.
  Incorrect SNC Name: The SNC name being used may be incorrect or not properly formatted.
  Profile Parameters: The necessary profile parameters for SNC may not be set correctly in the SAP system.
  
  Solutions:
  
  
  Check SNC Configuration:
  
  Ensure that the SNC is properly configured in both the SAP system and the client. Verify the SNC parameters in the SAP profile (e.g., snc/enable, snc/identity/as).
  
  
  
  User Mapping:
  
  Verify that the SNC name of the caller is correctly mapped to an SAP user. You can check this in transaction SU01 or SU10 by looking for the user with the corresponding SNC name.
  
  
  
  Create or Update User:
  
  If the user does not exist, create a new SAP user with the appropriate SNC name. If it exists but is locked or inactive, unlock or activate the user.
  
  
  
  Check SNC Name Format:
  
  Ensure that the SNC name is in the correct format. It should typically follow the format SNC:<SNC_NAME>.
  
  
  
  Review Profile Parameters:
  
  Check the profile parameters related to SNC in transaction RZ10 and ensure they are set correctly. Parameters like snc/identity/as and snc/identity/peer should be reviewed.
