Calculating Utilisation Rate

[Jazz_MT]

Hi All,

I am trying to calculate a utilisation rate which has the following formulate:

Utilisation  = Days Rented/Available Days

What I am finding funny is that for each individual year, month and room no the Utilisaiton rate is correct as per the above screenshot but then for the Total it is Incorrect as it is not summing the Available Days Correctly. Can anyone help out here ? 

Thanks,

Jake

@Jazz_MT cannot see the images, I assume these are measures you created. Do you have put any condition in the measure. Can you provide more details?

HI All, 

Attaching the Image 

The only measure I created for is Utilisation the others are pulling the data Directly from Tables.

hi, @Jazz_MT

This looks like a measure totals problem. Very common. See the post about it here: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Dealing-with-Measure-Totals/td-p/63376

Also, this Quick Measure, Measure Totals, The Final Word should get you what you need:

It looks like the "Available Days" column is aggregating incorrectly. I plugged some of the sample data into an excel workbook at the grain I see in this table:

I then just used your model for Utilization: 

Utilization = SUM(Sheet1[Days Rented]) / SUM(Sheet1[Available Days])

When I put all of this in a table, it looks correct on my end:

You can see in the image you provided that your Available Days only sums to 365, which is why your % value is so large. Is your data structured differently than what I provided above? Fixing how that value is summed is going to be the trick here I think.

Hi,

Out data model is different as it Counts the Rental Agreements in the Rental Agreements Granular table and based on the Month of the Rental PowerBI is obtaining the Available Days from the Date_table by counting the number of days in that particular month. 

Utilisation is basically being worked out as follows COUNT(Rental_Agreement)/COUNT(Rental_Date) i.e. Days Rented/DaysAvailable.

What PowerBI is counting the total number of the rows instead of summing the available days.

Thanks,

Jake

I'm still thinking about how to make this work in the context of your data structure.

In the meantime, I have two questions/concerns about the screenshot you provided. In your table, you are slicing by both Year/Month as well as Room Number. First, is there ever a scenario where an individual room number could have more days rented than available days in month? I'm seeing some of your cases where there are 37 Days Rented against 31 Available Days - I'm wondering if this is a bad count. Maybe this represents total number of rentals, rather than unique days on which rentals occured.

Second, by including room number in your visual, you might be inflating your total number of "Days Rented." For example, if two room numbers were both rented all 31 days, in your aggregation that will look like 62 Days Rented/ 31 Available Days. I'm thinking part of the solution to this might be removing Room Number from the table, and simply providing the ability to filter on this field. 

Obviously, I might be misinterpreting your data and it might be a requirement to include that in the visual, so this might not work for you.

I believe I ran into the same issue using counts and it not aggregating correctly. Use your existing measure that works on a per row basis in a total function. See below:  

Utilization Rate = 
IF(
    HASONEVALUE('TABLE1'[Rental_Agreement]),
        [Existing Measure],
    SUMX(VALUES('TABLE1'[Rental_Agreement]),
        [Existing Measure]
    )
)

@Jazz_MT you have to use different aggregation at total level using hasonefilter etc.

if you can put sample data in an excel sheet I will put together something for you. Thanks

I'm having trouble viewing the image you tried to attach. Could you try including it again?
