Difference between 2 columns

[j3n5k1]

I have a matrix like the below where I have swapped the values to rows. What I would like is to create another column showing the difference between Current and Prior Year for all metrics. If I create them individually they go below the other metrics and I want to see this as a column like below. 

Is there a way of doing this?

	Prior Year	Current Year	Difference
Growth
Cancels
Retention %

Hi @j3n5k1 ,

Please try:

First add a new column to the table:

Then creaet a new table:

Manage relationship:

Apply the measure:

Sum of Cancles = 
var _a = FORMAT( CALCULATE(MAX('Dummy Data'[Year]),ALL('Dummy Data'[Year])),"General Number")
var _b = CALCULATE(SUM('Dummy Data'[Cancels]),FILTER('Table',[Year]=_a))
var _c = CALCULATE(MAX('Dummy Data'[Year]),ALL('Dummy Data'))
var _d = CALCULATE(SUM('Dummy Data'[Cancels]),FILTER(ALL('Table'),[Year]=FORMAT(_c,"General Number")))
var _e = CALCULATE(SUM('Dummy Data'[Cancels]),FILTER(ALL('Table'),[Year]=FORMAT(_c-1,"General Number")))
return IF(MAX('Table'[Year])="Difference",_d-_e,_b)

Sum of Growth = 
var _a = FORMAT( CALCULATE(MAX('Dummy Data'[Year]),ALL('Dummy Data'[Year])),"General Number")
var _b = CALCULATE(SUM('Dummy Data'[Growth]),FILTER('Table',[Year]=_a))
var _c = CALCULATE(MAX('Dummy Data'[Year]),ALL('Dummy Data'))
var _d = CALCULATE(SUM('Dummy Data'[Growth]),FILTER(ALL('Table'),[Year]=FORMAT(_c,"General Number")))
var _e = CALCULATE(SUM('Dummy Data'[Growth]),FILTER(ALL('Table'),[Year]=FORMAT(_c-1,"General Number")))
return IF(MAX('Table'[Year])="Difference",_d-_e,_b)

Sum of Transacted = 
var _a = FORMAT( CALCULATE(MAX('Dummy Data'[Year]),ALL('Dummy Data'[Year])),"General Number")
var _b = CALCULATE(SUM('Dummy Data'[Transacted $]),FILTER('Table',[Year]=_a))
var _c = CALCULATE(MAX('Dummy Data'[Year]),ALL('Dummy Data'))
var _d = CALCULATE(SUM('Dummy Data'[Transacted $]),FILTER(ALL('Table'),[Year]=FORMAT(_c,"General Number")))
var _e = CALCULATE(SUM('Dummy Data'[Transacted $]),FILTER(ALL('Table'),[Year]=FORMAT(_c-1,"General Number")))
return IF(MAX('Table'[Year])="Difference",_d-_e,_b)

Retention % = 
DIVIDE([Sum of Cancles], [Sum of Transacted])

NCVI = [Sum of Growth]-[Sum of Cancles]

Final output:

I have measures (growth, cancels, retention % etc) which are all normally showing as columns (values) in a matrix on PBI with date etc as rows. 

For this particular view i have used the "switch values to rows" so my table looks as described.

If I was doing this in excel, I would now have my dates at the top, measures down the side - and a simple C-B to create a new column showing the difference for each of those values for each of those date ranges. I just don't know if that is possible? I can't use the source file as it is all confidential, but I have created a simple file to show what I mean - Dummy Report

the "Prior Year" column is redundant.  Remove that.  For "Difference" add a standard YoY or YoY% measure.  (You can create these via quick measures too)

[j3n5k1]

This won't solve my issue - I have multiple metrics as rows and a YoY difference as you described will only impact one of them, plus this will then show as another metric (so go on the rows in how i have created the view), not as a new column.

I need the matrix to look as described in my question so the PY field is not redundant, it is necessary
