Hi Visali,
The Mass Import option in HANA studio allows you to import all table definitions from SAP ERP source
systems using SAP Load Controller into SAP HANA database. Is this the option you are refering to? My version of HANA is version 1.0.35 and the option is called Mass Import of Meta Data. Im not aware of a restriction of import of tables of either format.
Kind regards,
Danielle
