Help with measures and logic with selected date

Hi Power BI Community!

I am working in a case for counting available housingunits for a studentvillage and I could really use your help.

What I would like to create is a measure counting the available housingunits categorized by housingtype for a specific date selected in a date slicer.


We have 3 tables: reservations, housingunits & housingtype as shown in the diagram below. Reservations are a DireactQuery table whilst the others are in import mode.

So what I initially have done is to create a measure counting total housingunits and categorize them by housingtype.

Count of all units =

CALCULATE(DISTINCTCOUNT(housingunit[Housing Unit]),

GROUPBY(housingtype,housingtype[housingtypecode]),

USERELATIONSHIP(housingtype[housingtypeid], housingunit[housingtypeid]))
 

To calculate which ones are reserved we use the reservations table. A reservation is always created on a housingtype, but not always on a specific housingunit, which is why we can only get the count on housingtype level. For a housingunit to be available it needs to be available from the selected date in the date slicer +365 days.

 

Snippets of the tables with data follow below:
