  Schema Issues: The table might exist in a different schema than the one being queried.
  HANA Database State: The HANA database might be in a state that prevents queries from being executed, such as being down for maintenance or experiencing performance issues.
  
  Solutions:
  
  
  Check Database Connection:
  
  Verify that the connection to the HANA database is active and correctly configured.
  Test the connection using a database client or through the SAP system.

  Ensure that you are querying the correct schema where the table is supposed to exist.
  
  
  
  Check HANA Database Status:
  
  Confirm that the HANA database is up and running without issues.
  Look for any ongoing maintenance activities or performance problems.
  
  
  
  Use SQL Console:
