If you download the AdventureWorks tabular model from CodePlex, then the files are marked ‘read only’. When I tried to open the file, I got a number of things happening. I’ve now changed so it isn’t read-only – no surprise there!
– I couldn’t see any of the ‘normal’ buttons in Visual Studio. So, for example, I had ‘Tools’ and ‘Window’, but I couldn’t find ‘Table’ and ‘Column’.
You need to point the tabular model at your on instance of the tabular model in two places:
– Click on the Model.bim file, and select ‘Properties’ and point the tabular model at the correct instance
– Click on the Project, and select the updated Properties information under ‘server’.
Then, double-click the Model name, and everything should be fine. You can see your buttons properly, and can process the tables and see the AdventureWorks data.
You will have to change the connection to the source database as well as the tabular model instance.
Hope that helps,
