How to build measure for % occupancy for hotel

[MalcolmLeong]

Here's a sample of what I am looking at:

1. I have several hotels.  In this case, Hotel A and Hotel B.

2. In each hotel, I have (i) a daily breakdown, and (ii) the segment breakdown contributing to the sales

3. I have a fixed room inventory for each hotel : hotel A (300 rooms a day) and hotel B (100 rooms a day)

Problem :

1. I need to build a robust measure for occupancy, which is (Room Nights / Inventory). 

2. The measure will stand whether I remove the segment and/or remove the dates

Here's how it will look like.  I am trying to calculate the green colum Occupancy %.

1. The measure can be broken down by day/by segment/by hotel, etc

2. But I should also be able to aggregate it for e.g. if I removed the segment, Hotel A will be 77% on 1 Dec (i.e. (80+100+50)/300)), or even if I remove the dates, Hotel A will be 71% on 1Dec and 2Dec aggregated (i.e. (80+100+50+50+120+30) / (300+300).

 

Here is how my data table actually looks like and I'm having difficulties in building the measure that I need:

Any help will be much appreciated!

@MalcolmLeong,

In your table, create the following measure.

Occupancy% = SUM(Table[Room Nights])/MAX(Table[Inventory])

For your last requirement that "even if I remove the dates, Hotel A will be 71% on 1Dec and 2Dec aggregated (i.e. (80+100+50+50+120+30) / (300+300)", please firstly create new table using DAX below.

NewTable = SUMMARIZE(Table,Table[Hotel],Table[Date],"room nights",SUM(Table[Room Nights]),"inventory",MAX(Table[Inventory]))

Then create the following measure in the new table.

percentage = DIVIDE(SUM('NewTable'[room nights]),CALCULATE(SUM('NewTable'[inventory]),FILTER('NewTable','NewTable'[Date]<=MAX('NewTable'[Date]))))
