Current versus last year on KPI visual

acg — Sat, 23 Apr 2022 09:30:21 GMT

I have data over several years, say from 2017 to 2021.

For some of the KPI, I worked out the counts of a variable for latest / max year (2021) versus the count of the earliest / min year where we have data from (2017).

Count of Audits conducted Max =

VAR MAXSD = CALCULATE(MAX('2017-2021'[Year]),ALLSELECTED('2017-2021'))

VAR MAXYSD = CALCULATE(MAX('2017-2021'[Year]),'2017-2021'[Year] = MAXSD)

RETURN

CALCULATE

(

COUNT('2017-2021'[Conducted]),

'2017-2020'[Conducted?] = "Y",

'2017-2021'[Year] = MAXYSD

)

and for the earliest counts the min:

Count of Audits conducted Min =

VAR MINSD = CALCULATE(MIN('2017-2021'[Year]),ALLSELECTED('2017-2021'))

VAR MINYSD = CALCULATE(MIN('2017-2021'[Year]),'2017-2021'[Year] = MINSD)

RETURN

CALCULATE

(

COUNT('2017-2021'[Conducted]),

'2017-2020'[Conducted?] = "Y",

'2017-2021'[Year] = MINYSD

)

-- both of these calculations work fine and as expected.

What I want to do now is to have KPI with the counts of a variable for latest / max year (2021) and the previous year, 2020.

I thought I could just leave the MAX calculation as is, and change the MIN like this:

VAR MINSD = CALCULATE(MAX('2017-2021'[Year] -1),ALLSELECTED('2017-2021'))

VAR MINYSD = CALCULATE(MAX('2017-2021'[Year] -1),'2017-2021'[Year] = MINSD)

This does however not work. I think it is partly because the Max / Min functions only accepts a column reference as an argument.

So how can I get around this?

Is there a better way to solve this altogether?

Hi acg

you can use

VAR MINYSD =
MINX (
TOPN ( 2, ALLSELECTED ( '2017-2021' ), '2017-2021'[Year] ),
'2017-2021'[Year]
)

Hi @tamej1 et all, the solution provided seems not to work.

I give an example and make it slightly easier:

The Max I am using for te KPI measure is:

Count of Audits conducted Max =

VAR MAXSD = CALCULATE(MAX('2017-2021'[Year]),ALLSELECTED('2017-2021'))

VAR MAXYSD = CALCULATE(MAX('2017-2021'[Year]),'2017-2021'[Year] = MAXSD)

RETURN

CALCULATE

(

DISTINCTCOUNT('2017-2021'[Entity]),

'2017-2020'[Conducted?] = "Y",

'2017-2021'[Year] = MAXYSD

)

--------------

And for the Min / Last or previous year I used the solution suggested

Count of Audit Firms Last Year =

VAR MINYSD = MINX(

TOPN ( 2, ALLSELECTED ('2017-2020'),'2017-2020'[Year] ),

'2017-2020'[Year])

RETURN

CALCULATE

(

DISTINCTCOUNT('2017-2020'[Entity]) = MINYSD

)

I am getting this table output:

Below is the data I used.

How can I make this working?

Re: Current versus last year on KPI visual

tamerj1

as mentioned above, I tried the follwing:

Count of Audit Firms Last Year =

VAR MINYSD = MINX(

TOPN ( 2, ALLSELECTED ('2017-2020'),'2017-2020'[Year] ),

'2017-2020'[Year])

RETURN

CALCULATE

(

DISTINCTCOUNT('2017-2020'[Entity]) = MINYSD

)

I don't understand why it does not work, but I printed the output above. Just wanted to add that 'year' is a 'whole number. I tried to convert it to yyyy, but the output it gave me was 1905 throughout. So I reverted it back to whole number. Maybe that is part of whyt it does not work that what. I thought your solution was as such neat, as you just say, take the second year.

So I have found now a solution, which I show below.

However, for whatever reason it is tremendouly memory hungy to the point that it is not sustainable.

Has anyone a better solution??

This works, but as said: at a cost

Count of Audits conducted Min =

VAR MINSD = CALCULATE((MIN('2017-2021'[Year])-1),ALLSELECTED('2017-2021'))

VAR MINYSD = CALCULATE((MIN('2017-2021'[Year])-1),'2017-2021'[Year] = MINSD)

RETURN

CALCULATE

(

COUNT('2017-2021'[Conducted]),

'2017-2020'[Conducted?] = "Y",

(('2017-2021'[Year])-1) = MINYSD

)

acg — Sun, 24 Apr 2022 12:27:29 GMT

Ok Solution found:

Count of Audits conducted Min =

VAR MINSD = CALCULATE((MIN('2017-2021'[Year])-1),ALLSELECTED('2017-2021'))

VAR MINYSD = CALCULATE((MIN('2017-2021'[Year])-1),'2017-2021'[Year] = MINSD)

RETURN

CALCULATE

(

COUNT('2017-2021'[Conducted]),

'2017-2020'[Conducted?] = "Y",

'2017-2021'[Year]= MINYSD

)
