Customers who bought parking slot with apartment



I'm investigating apartment and parking slot sales. I need to calculate how many apartment sales will be bought with a parking slot. 


1 Housing Company have parking slots and apartments.

1 apartment sale can be bought by multiple customers.

There is scenario that 1 apartment is sold with 1 parking slot to 2 customers but only 1 customer from these 2 customers bought the the parking slot. In this case the apartment is sold with parking slot.


The desired result would be like:


Apartment 1 Bought with parking slot

Apartment 2 Bought with parking slot

Apartment 3 Not bought with parking slot


After that I could make a analysis with different Housing companies with % of housing purchases with parking slot.




Any ideas?

So like this?


Measure = 
    VAR __All = COUNTROWS(FILTER('Items',[Type]<>"Parking Slot"))
    VAR __ParkingSlots = COUNTROWS(FILTER('Items',[Type]="Parking Slot"))
    __ParkingSlots / __All


PBIX is attached.

Re: Customers who bought parking slot with apartment



Thank you for your reply @Greg_Deckler . This is still not enough. 


There can be a multiple bueyrs for apartment and the measure needs to be calculated per one apartment. So if there is 3 buyers for the apartment x and one of them buy one parking slot from the same housing company, the dax should say that the apartment was sold with parking slot.


I tried to make a dax but it does not work.


Apartment sales with parking spot =
var selectedcustomer = VALUES(Customers[CustomerID])
var selectedhousingcompany = VALUES('Housing companies'[HousingCompanyID])
var apartmentsales = CALCULATE([Apartment sales];selectedcustomer;selectedhousingcompany)
var parkingslotsales = CALCULATE([Parking slot sales];selectedcustomer;selectedhousingcompany)
