This error typically occurs in the context of SAP BW (Business Warehouse) when dealing with near-line storage, which is used to manage large volumes of data efficiently.
  Cause:
  The error message RSDA490 is triggered when there is a mismatch between the near-line object associated with a data request and the expected near-line object. This can happen due to several reasons, including:
