Dynamic metrics using field parameters and calculaton groups

[roy_menger]

Hi all,

I'm trying to build the following: 

there are multiple metrics, lets say: sum(sales) and count(orders). In both cases there are different versions (Actual and Budget). I want to have two dropdowns where you can select either Act or Bud (or have both the same), and then a table that shows two columns (one for the selected value in the first dropdown, one for the selected value in the second dropdown). The selected dropdown values obviously are applied as filters to the respective metrics. There should also be an option to switch between sales and orders (2 metrics). The column names the tables should be either 'Act' or 'Bud', depending on the selected values in the 2 dropdowns. 

This seems like are relatively easy scenario, but I have tried every possible combination of calculation groups and field parameters and I cannot seem to get it working. Any suggestions would be very helpful.
