I am trying to find a workaround to the fact that Tableau (v7) does not allow custom hierarchies to be built on SSAS dimensions.
This is stopping us from having an interactive dimension that will allow a user to select from a number of hierarchies presented via a drop down.
I understand that all hierarchies must be created in SSAS but what I cannot understand is how I can make this interactive based on a user drop down in the dashboard.
Has anyone figured out a neat way to do this?
What I was thinking is that if I could create a hierarchy in SSAS that essentially creates a union of the required members with one attribute "type" to represent the user definable (dropdown), then
Lvl1 Lvl2 Lvl3 Type
ALL ANZ AU Region
ALL ANZ NZ Region
ALL Fruit Kiwi Category
If this is not possible, would there be any way of having pairs of parameters that would allow users to select a level in a hierarchy and the member required for each. One selecting, the hierarchy would be built based on the parameters supplied.
Essentially we need a flexible solution that will give the user the ability to define which hierarchy is presented on the dashboard.
