I'm trying to create my first SSAS Tabular model. I'm following the steps mentioned in following tutorial:
https://msdn.microsoft.com/en-us/library/hh231690.aspx
While trying to load the tables to the model, I get the following error:
Blockquote

What shall I do to get rid of this error message?
I'm using SQL Server 2014 and Visual Studio 2015 (SSDT).
