DAX year comparison - Why does this not work?

mark77 — Tue, 31 May 2022 07:56:03 GMT

Hi. I'm trying to set up a number of standard formula to be used in my PBI reports.

users are supposed to select 1 year. Also they can select additional filters such as YTD and whatever you have .

In any case :

Asume selected is (only) 2022 in the date filter.

(The following works)

TEST_TY =

VAR __YEARSELECTION = CALCULATE(MAX('Date'[Year])-0)

VAR __BASEFORMULA = CALCULATE([Product SO],FILTER('Date','Date'[Year]=__YEARSELECTION))

RETURN

__BASEFORMULA

(This does not - Except then selecting both 2022 AND 2021)

TEST_TY =

VAR __YEARSELECTION = CALCULATE(MAX('Date'[Year])-1)

VAR __BASEFORMULA = CALCULATE([Product SO],FILTER('Date','Date'[Year]=__YEARSELECTION))

RETURN

__BASEFORMULA

Why does the following above not work? How do I override the 2022 selection?

TEST = CALCULATE(sum(_actuals[product_sales_eur]),FILTER('Date','Date'[Year]=2021)) also does not work

Please not that I do not only want to look 1 year back, but will want to do 2020 aswell etc.

Thanks!

mark77 , You need to use all

TEST_TY =
VAR __YEARSELECTION = CALCULATE(MAX('Date'[Year])-1)
VAR __BASEFORMULA = CALCULATE([Product SO],FILTER(all('Date'),'Date'[Year]=__YEARSELECTION))
RETURN
__BASEFORMULA

Hi amitchandak ,

Thank you for your response. Unfortunately this does not yield the required result. I had tested with all myself, but that will generate a grand total for me.

As you can see with the (modified) data here, the calculation falls apart in a table.

And I really do want to use a great many tables in many variants 😉

Do you know how I'd be able to resolve this ?

The Formula does respond correctly to filters though. For example a subcompany was selected here.
