Hello,
you can publish the BW data as HANA models in two ways; importing via the HANA studio or exporting via the BW backend
I would recommend the backend approach. There you can expose BW Queries as HANA views, the HANA views are part of the BW lifecycle and automatically adjusted. They are then also part of the BW transport.
General information:
BW Query as HANA view:
