DAX Formula for Average Unique Email Open Rate

[ChrisDg]

Hi,

I am trying to figure out how to create a DAX formula for the average of another DAX formula. I already created a formula for showing the unique open rate:  

Open Rate = SUM(Combined_EmailGroupOverview[Unique Opens])/SUM(Combined_EmailGroupOverview[Total Delivered])

This works correctly, but now I need to do an Average Open rate of all of the Open Rates from the DAX 'Open Rate' calculation, which I don't know how to do. 

I tried these formula:

Average Open Rate =

AVERAGEX(

   VALUES(Combined_EmailGroupOverview[Email Subject Line]),

   [Open Rate]

)

And this formula:

Average Open Rate by Content Type =

AVERAGEX(

   VALUES(Combined_EmailGroupOverview[Content Type]),

   DIVIDE(

       SUM(Combined_EmailGroupOverview[Unique Opens]),

       SUM(Combined_EmailGroupOverview[Total Delivered]),

       0

   )

)

It got me these results when I filtered for the average open rate based on content type: 

I know these averages aren't right and the 2nd formula just gave me the same result as the regular open rate formula. For example, if I see these open rates: 100.00%, 100.00%, 100.00%, 50.00%, 39.13% then I want the average to be 77.83%.

I want to do the average open rates of many different categories: content type, email send date, email subject line, etc. Do I have to do different formulas for each category that I want the averages from? This also spans across 5 years worth of data and over 1 millon rows.

Thank you,

Hi Ibendlin,

Sorry to post a screenshot. I've tried adding my sample data set multiple different ways and it keeps giving me this error:

Sometimes it will let me post the sample data set and it says that the content has posted, but when I refresh the page the comment disappears.

Is there another way to do this or am I doing something wrong?

Thank you,

Chris

Hi Ibendlin,

I now see the sample data uploaded correctly based off of the link. It shown as Message 3 of 6. It must have had a lag in uploading.

Thank you,

You cannot measure a measure directly. Either materialize it first, or create a separate measure that implements the entire business logic.
