Hi Subba,
really really curious.
Referring to HANA Administration Guide, to import a catalog object you need System privilege IMPORT and SQL privilege INSERT for the specific catalog object.
That's 100% correct when you create a new schema (you need CREATE SCHEMA system privilege) and, using import wizard, you try to import data inside auto-created tables.
However it looks like (I tried few minutes ago) you have the possibility to import data through the import wizard on your "personal" schema - the schema automatically created and labeled with your username.
Is "SCHEMA 1" your personal schema?
Regarding note2, when you create a table inside any schema (with CATALOG READ system privilege you have access to all the schema), you become the "owner" of such table and so you automatically receive INSERT, UPDATE, SELECT, TRUNCATE, ... SQL privileges on it.
