Variance calculation in Table or Matrix

Hi everyone   I'm doing a sales comparison report in which the end user can pick any 2 dates in a slicer (2016 and 2021 in below example). To show the results, I'm trying to achieve this vis...

    Hi AnthNC ,

     

    Based on your description, I have created a simple example:

    Please try:

    Measure = 
var _a = CALCULATE(SUM('Table'[Value]),FILTER('Table',[Year]=MIN('Table'[Year])))
var _b = CALCULATE(SUM('Table'[Value]),FILTER('Table',[Year]=MAX('Table'[Year])))
return 
IF(ISINSCOPE('Table'[Year]),SUM('Table'[Value]),FORMAT(DIVIDE(_b-_a,_a),"Percent"))

    Change the name of  column subtotal:

    Final output:

    Best Regards,

    Jianbo Li

This is a very clear example thanks for that.

 

Question, I'm computing a numeric rather than percentage variance. In my (very large) dataset there may be instances where the "subcategory" isn't present in a "year". How can I incorporate COALESCE into the above in order to compute a variance where for a given "subcategory", one "year" is BLANK?

 

I've tried inserting in both the variables and in the IF(INSCOPE line without any success.

 

subcategory20162018Variance
a 9090
b208060
c307040

 

I would've thought this usage of COALESCE would accomplish my objective but I'm stuck:

 

Measure =
var _a = COALESCE(CALCULATE(SUM('Table'[Value]),FILTER('Table',[Year]=MIN('Table'[Year]))),0)
var _b = COALESCE(CALCULATE(SUM('Table'[Value]),FILTER('Table',[Year]=MAX('Table'[Year]))),0)
return
IF(ISINSCOPE('Table'[Year]),SUM('Table'[Value]),COALESCE(_b,0) - COALESCE(_a,0))
