Hi SAP BI,
First of all, it will help if you can use your real name as per the forum guidelines and policy. 
It seems like you have authorization issue as you posted similar message for not being able to see HANA views from IDT / Excel.
I am sure a quick search on this forum would have pointed you to the right threads and will provide you all the required information.
Please refer to a thread with similar issue discussed. The user id you are using to connect to HANA should have access to _SYS_BIC to see the HANA views.
