Yes, you are right Mr Zhou, I saw that too late, after posting the question, since I was very confused.
I have to understand better how to handle this importing things, cause it is not working even after creating an hdbti object. If you have any suggestion step by step to make a good import working, I will be glad to follow that (by the way, I'm using SYSTEM as user in my HANA Studio).
Have a nice day,
Best regards,
Denis
