Market value weighted construction year

[beasta]

I already searched the forum and couldn't not find the solution so far. I created a measure for the market vlaue weighted construction year of a real estate portfolio. This works fine as long as I select the whole portfolio or a single property but as soon as I have two properties it doesn't work anymore. This is because of the market value weightings (MV%) which is based on the whole portfolio but how can I make the MV% dynamic? What I mean, if I for e.g. select the canton VD (5 properties) the weighted construction year is 281 instead of  1984.

many thanks for your help! (how can I upload an example of the measures I did?)

Hi,

Please change your original [MV_tot] to this:

MV_tot = CALCULATE(SUM(Sheet1[Market Value]), ALLEXCEPT(Sheet1,Sheet1[Cantone])) 

The result shows:

See the attached pbix file.

Many thanks for your reply and sorry for my late response, I was on vacation. 

This actually only solves part of the problem. When you deselect VD, you get a weighted Construction Year of 15697 which is certainly not correct. I'm looking for a solution, where the weightings adapts itself depending on the selection, no matter whether it's the canton, the location or rental income. Isn't there a way to have the weightings dynamically depending on the selection/filter?
