Measure to show also previous month using slicer

[Bohumil_Uhrin]

Hi,

Im trying to do the following:

I have visual with 2 measures:

Amortisation value actual month = calculate(sum(data[Amortization value]),filter(data,data[Month]=[max month]))

Amortisation value previous month = CALCULATE(sum(data[Amortization value]),All(data[Month]),filter(data,data[Month]=[max month]-1))

[max month] is defined as = max(data[Month])

The point is to use slicer to select actual month, and in the visual compare selected month with previous one.

Im using All() function to ignore slicer selection.

But somehow, the previous month measure returns blank values. Any idea why is that and how can I approach this?

Thank you in advance.

is your data[Month]  a date field or a number field? what happens if the month is January?

Did you notice that you subtract 1 twice?

[Bohumil_Uhrin]

data[Month] is number field

yeah, I subtracted twice - I corrected

I have data only for months 3-9. When I select the smallest (3), its the same - blanks.

I shared file on onedrive: https://1drv.ms/u/s!AsS4aATA1W9agqQtzmF_2oMhuMB6aA?e=YmOQXZ

thank you very much for your help

Hi @Bohumil_Uhrin ，

You can use the following measure, and it will show what you want:

Amortisation value prev = 
VAR prev_month = MAX(data[Month])-1
RETURN
calculate([Amortisation value],filter(ALLEXCEPT(data,data[Material]),data[Month]=prev_month))

If this post help, please consider accept it as the solution to help other member find it more quickly.

hi, yes, I was using measure for [max month], but with the variable its the same - Im geting blank values

Amortisation value prev =

VAR prev_month = MAX(data[Month])-1

RETURN

calculate(sum(data[Amortization value]),ALL(data[Month]),filter(data,data[Month]=prev_month-1))

is [max month]  a measure?  Use a variable instead.
