This error indicates that the SNC name, which is necessary for establishing a secure connection, has not been specified in the command line or the environment variables.
  Cause:
  
  Missing SNC Name: The SNC name is not provided in the command line when starting the SAP application or is not set in the environment variables.
  Configuration Issues: The SNC settings in the SAP system may not be correctly configured, leading to the system being unable to find the necessary SNC name.
  Incorrect Environment Variables: The environment variables related to SNC may not be set correctly or may be missing.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Command Line:
  
  If you are starting the SAP application from the command line, ensure that you include the SNC name in the command. The syntax typically looks like this:
  sapshcut.exe -system=<SAP System> -snc=<SNC Name>
  
  
  
  
  Set Environment Variables:
  
  If you are not using the command line, you can set the SNC name in the environment variables. You can do this by:
  
  On Windows:
  
  Right-click on "This PC" or "My Computer" and select "Properties".

  Check SAP Profile Parameters:
