This error indicates that the system cannot find the necessary metadata for a hierarchy in the source system, which is essential for processing the data correctly.
  Causes:
  
  Missing Hierarchy Metadata: The hierarchy you are trying to use may not have been loaded or activated in the BW system.

  Solutions:
  
  Check Hierarchy Definition: Verify that the hierarchy is correctly defined in the source system. Ensure that it exists and is active.

  Re-activate the DataSource: If the DataSource is not active, you may need to re-activate it in the BW system.
  Check for Transport Issues: If the hierarchy was transported, check the transport logs to ensure that all necessary objects were included in the transport.
