Hi Siddhartha,
There are different ways to transport the content depending upon what is to be transported.
You can transport HANA Artifacts or data (tables/runtime objects)
SAP HANA Artifacts (attribute views/analytic views/ calculation views) can be transported via Delivery unit as Import/Expot or via Transport request as well.
Run time objects have their own mechanism of import/export as direct or via a data provisioning tool depending upon is it one time activity or should happen on scheduled basis.
Regards,
Anjali.
