DAX _ Calculate occupancy rate

[Randcharles]

Hi all, 

I have a report where I need to calculate occupancy rate : office reservation/ available desk.

When I need to compute the global occupancy rate for a  month or a week , it shows a wrong rate. 
Example : I have 4 available desks in a month, and 12 people did reservation for a month (number of reservation). 
So when I calculate the rate = DIVIDE( Number of reservation, Available desk), it gives a wrong data as 300%.

Could anyone help how to fix this kind of evaluation context problem in DAX ?
Here is my data model :

Thanks in advance.

@Randcharles , For this first make sure you have one date table 

Then Create a measure for Daily reservation

DailyReservations =

CALCULATE (

    COUNTROWS(Reservations),

    ALLEXCEPT(Reservations, Reservations[ReservationDate])

)

Then one more for Desk

DailyOccupancyRate =
DIVIDE (
[DailyReservations],
COUNTROWS(Desks)
)

Then create measure for monthly 

MonthlyOccupancyRate =

AVERAGEX (

    VALUES(DateTable[Date]),

    [DailyOccupancyRate]

)

Hi @Randcharles ,

Your calculation is based on your data model and your tables. Please share a sample file with us.

We need to know how to calculate Number of reservation and Available desk.

You can also show us the result you want, this will make it easier to find the solution.
