I believe that the MSDN Analysis Services tutorial and AdventureWorks files on Codeplex aren’t quite matching up.
For the tutorial ‘Using a Modified Version of the Analysis Services Tutorial Project’ (http://msdn.microsoft.com/en-us/library/ms166582.aspx), the reader is instructed to download the file ‘SSAS Multidimensional Model Projects SQL Server 2012.zip’
The reader is directed to ‘Browse to the Lesson 4 Start folder’ but this isn’t contained in ‘SSAS Multidimensional Model Projects SQL Server 2012.zip’
Instead, you find the folder ‘Lesson 4 Start’ in ‘Analysis Services Tutorial SQL Server 2012.zip‘
I hope that helps someone to get five minutes of their life back 🙂
