  The SAP error message R8509, which states "There are still no BW systems connected to the DataSource," typically occurs in the context of SAP BW (Business Warehouse) when trying to replicate or manage DataSources. This error indicates that the DataSource you are working with is not connected to any BW system, which is necessary for data extraction and loading processes.
  Cause:
  
  No BW System Assigned: The DataSource has not been assigned to any BW system. This can happen if the DataSource was created but not yet linked to a BW system.
