A possible solution:
In Tableau Create excel as the data source, with drop-down menu using validation and any other formatting to create the interface.
Upload this to SharePoint document library, Excel web apps will enable authorised users to edit within the browser (intranet page). Connect live to this data source in Tableau, and theoretically should update reports.
Hope that helps.
Hi Russel Christopher -
Here's an idea that gets you the "incorporate a drop down box / text entry box on the detail panel". Add a parameter to the view with the different options, then have a single URL Action that uses the dimension values from the view *and* the parameter (and you can even put the parameter name in the Action title). If you put the worksheet in the dashboard, you can even float the parameter selection over the map.
The user interaction flow would then be:
1) see the view
2) choose the parameter
3) hover over the mark
4) fire off the action
Here's a quick demo using CoffeeChain:

Hi Jonathan -
Ohh, I really like the ability to include <Parameters.Choose Action> in the title and url string! Very nice!
