Hi Lance, the short term solution is to use one of the methods detailed here: Filtering Data Across Multiple Data Sources | Tableau Software. Basically you can either set up a parameter to control both views, or set up a dashboard action to use a control sheet as a filter. The good news is that this is about to get a lot easier with cross-database join in Tableau 10.
Appreciate the data reference mate, however I did happen onto your provided link in my search for a resolution.
Try as I may I was not successful in configuring my workbook to match any of the two proposed examples.
I have no doubt that I was “forest gumping” basic calcs during my pursuit,
All good, I’ll hold on for the release of v10
