Find differences between 2 selected rown in a table

Hello everyone,

 

In my work we have monthly mailing campaigns to selected donors from our database, where each campaign record has a number of fields, for example

  • Number of people mailed
  • Number of reponses with donation
  • Value of donations received

What I want to do is simply select 2 campaigns by their reference number (via a filter) and calculate the differences in these values.

 

A very simple example:

CampaignNr MailedNr ResponsesValue of Donations
111111000502000
222221100401900
Differences-10010100

 

Displaying the values for each campaign is very easy, but finding the differences is not ...

 

Any suggestions gratefully received!

 

Thank you in advance and kind regards,

John

  • johnstrang - This will take multiple steps.

     

    1) Set up two DAX Calculated tables that will allow you to select a Campaign:

     

    Campaign 1 = VALUES( 'Table'[Campaign] )
    
    Campaign 2 = VALUES( 'Table'[Campaign] )

     

    2) If you get a relationship created with either of these tables, ensure they are deleted. 

     

    3) Create a measure that finds the values you want based on a slicer selection and then performs the calculation:

     

    Difference = 
    
    VAR _campaign_1 = SELECTEDVALUE( 'Campaign 1'[Campaign] )
    
    VAR _campaign_2 = SELECTEDVALUE( 'Campaign 2'[Campaign] )
    
    VAR _value_campaign_1 = CALCULATE( SUM( 'Table'[Column] ), KEEPFILTERS( 'Table'[Campaign] = _campaign_1 ))
    
    VAR _value_campaign_2 = CALCULATE( SUM( 'Table'[Column] ), KEEPFILTERS( 'Table'[Campaign] = _campaign_2 ))
    
    RETURN
    _value_campaign_2 - _value_campaign_1

     

    Just replace my 'Table' and [Column] references with the names from your model.

    After thoroughly reviewing the details you provided, I was able to reproduce the scenario, and it worked on my end. I have used the sample data on my end and successfully implemented it.  


    I am also including .pbix file for your better understanding, please have a look into it:
