We are currently connecting to Tableau using a SSAS Tabular Cube. The speed is great and everything is working very well. I am having a little difficulty of the aesthetics of the Tableau desktop- mainly the measurements section. Is there a way to order the measures - either alphabetically or by table or something. I am unable to give this final approval to send to end users unless we solve this.
When you use regular olap cubes you can add display folders to your measures for grouping.
It looks like the same functionality is available for tabular models: http://www.sqlbi.com/articles/organizing-measures-and-attributes-in-folders-with-tabular/
Hope it help
