Data source Tab not enabled While using SSAS Import Option

[arun_1047]

Hello,

Sceanrio:

  Under Prod Server, we do have many SSAS Cubes. I wanted to get each cubes Last Processing Date.

Following are the steps which i performed in the Power BI Desktop

1) Created SSAS Analysis Service connection (using Import Option).

2) Changed the Access type to Basic from Windows credential

3) Pulled the record from Meta data 

4) Created a report and published to the Report Server.

5) If i want to change the  credential from account to system account. When i looked and Datasource section it is completely

disabled in the power BI Oct GA version

Please let me know is there any other way  i can get the cube Last processing date directly without using (OpenQuery/OpenRowset in SQL)
