Hi Kang,
I don't believe you can import BW SPO objects using this procedure. Please see the information in the SAP note 1764251:
"
You use this feature to import SAP NetWeaver Business Warehouse (SAP NetWeaver BW) models that are SAP HANA-optimized InfoCubes,
SAP HANA-optimized DataStore objects, Standard DataStore Objects, and Query Snapshot InfoProviders to the SAP HANA modeling environment.
"
Kind Regards,
Des
