DAX - Difference between min and max year
Hello Power BI community,
I need help coming up with a DAX formula to calculate the difference between the minimum (lowest selected) fiscal year and the maximum (highest selected) fiscal year.
To summarize, I would like to subtract the lowest selected fiscal year from the highest selected fiscal year. In the screencapture below, the rate should read as -1% (4% in 2017/2018 MINUS 5% in 2014/2015) .
Here is what I have so far:
Min and Max Year Rate Change =
CALCULATE(
SUM('Master'[Rate]),
FILTER('Master','Master'[Fiscal Year]=MAX('Master'[Fiscal Year])
)
),
-
CALCULATE(
SUM('Master'[Rate]),
FILTER('Master','Master'[Fiscal Year]=MIN('Master'[Fiscal Year])))
,0)
The expression above yields the following error message:
To use special characters in a measure name, enclose the entire name in brackets ( [] ) and add a ] to any closing brackets in the name.
Sample workbook with altered data below for reference:
| Fiscal Year | Rate |
| 2006/2007 | 9.1% |
| 2007/2008 | 5.6% |
| 2008/2009 | 3.7% |
| 2009/2010 | 16.9% |
| 2010/2011 | 16.4% |
| 2011/2012 | 15.3% |
| 2012/2013 | 8.9% |
| 2013/2014 | 8.9% |
| 2014/2015 | 4.6% |
| 2015/2016 | 16.7% |
| 2016/2017 | 15.1% |
| 2017/2018 | 2.1% |
| 2018/2019 | 10.6% |
Any help on the matter would be greatly appreciated :) thank you!
Didn't dig into what is potentially wrong with your formula, and I got a positive 2.5 with the data you supplied. 4.6 - 2.1
Measure 2 = VAR __max = MAX('Table5'[Fiscal Year]) VAR __min = MIN('Table5'[Fiscal Year]) RETURN SUMX(FILTER('Table5',[Fiscal Year]=__min),[Rate]) - SUMX(FILTER('Table5',[Fiscal Year]=__max),[Rate])
