Missing privileges on Hana Cloud Trial

Hello Experts,

I am trying to follow one document :

http://help.sap.com/openSAP/HANA1/openSAP_HANA1_Week_01_How_to_Import_Delivery_Units.pdf

Here in a particular step "Start the import of the delivery units: " I am getting below error :

"Insufficient privileges to perform Import Server operation".

So I looked up internet on this issue and I found that I am missing on few privileges as mentioned in below thread.

What are these missing privileges ?

Most Important Query is - How can I get these privileges ?
