Import data from SSAS: Auto Exist operation exceeding permitted memory limit & is being canceled

I am evaluating Power BI Desktop, so I decided to deploy the AdventureWorksDW2012 multidimensional cube and connecting to it from Power BI.

I have a SQL Standard ilcence, so i cannot choose "Live connection" and I am using the "Import data" option.

When i select, for example, Customer Geography hierarchy within the Customer dimension, I receive a datasource error telling me that "Auto Exist operation exceeding permitted memory limit & is being canceled".

I have no other info or detail.

Can you help me?

Thanks in advance.

Regards,

Emi.
