• What is the cause and solution for SAP error message ESH_ENG_CDS_HANA005 - Schema cannot be determined from DB-connection ?

  The SAP error message ESH_ENG_CDS_HANA005: Schema cannot be determined from DB-connection typically occurs in the context of SAP HANA when there is an issue with the database connection or the configuration of the database schema. This error is often related to the use of Core Data Services (CDS) views in SAP HANA.
  Causes:
  
  Database Connection Issues: The connection to the HANA database may not be properly configured, or the connection parameters may be incorrect.
  Missing Schema Information: The schema that the CDS view is supposed to reference may not be specified or may not exist in the database.
  User Permissions: The user account used for the database connection may not have the necessary permissions to access the specified schema.
  Incorrect Configuration: The configuration settings in the SAP system (like the Data Source or the connection settings) may not be set up correctly.
  Transport Issues: If the CDS views were transported from one system to another, there may be inconsistencies in the schema definitions.
  
  Solutions:
  
  
  Check Database Connection:
  
  Verify the database connection settings in the SAP system (transaction DBACOCKPIT or SM59).
  Ensure that the connection parameters (host, port, user, password) are correct.
  
  
  
  Specify Schema:
  
  Ensure that the schema is explicitly defined in the CDS view definition. You can do this by using the @AbapCatalog.schema annotation in your CDS view.
  
  
  
  User Permissions:
  
  Check the user permissions for the database user. Ensure that the user has the necessary privileges to access the schema and the objects within it.
  
  
  
  Review Configuration:

  Check if the Data Source is correctly defined and points to the right schema.
  
  
  
  Transport Consistency:
  
  If the issue arose after a transport, check the transport logs and ensure that all necessary objects were transported correctly.
  You may need to re-transport the CDS views or related objects to ensure consistency.
