how to get from selected value (slicer for Year/Month) -1 year in dax

[TomaKavi]

Hello guys, 

I have a measure in dax which shows values for selected Year/Quarter in a slicer. I need to create another one which will show the results for the same Quarter but a Year back.Is there any dax function which might help ? I take the slicer from the column below so a YEAR -1 wont help me.

Hi @TomaKavi ,

If you want, for example, select 2022/Q3 in the slicer, but the result returns the value of 2021/Q3. Then the table of this slicer field needs to have no relationship to the table in your results visual.

Here's an example for reference.

The main table:

The YearQuarter table:

No relationship:

Create a measure as the visual-level filter.

Measure = var _year=SELECTEDVALUE('YearQuarter'[Year])
var _quarter=SELECTEDVALUE('YearQuarter'[Quarter2])
return IF(ISFILTERED('YearQuarter'[YearQuarter]),IF(_year-1=MAX('Table'[Year])&&_quarter=MAX('Table'[Quarter2]),1),1)

Now the table visual is from the main table. And the slicer is from the YearQuarter tabel.

Put the measure into the visual-level filters in the table visual. Set up show items when the values is 1.

Result:

hello, thanks, can work, but I have already created a different method. I have added another column in the date table, set 42022 for example as 4th Q for Y2022, set that as whole number, and in var where is selected specific Y/Q to use the new colum -1 and job done. But your solution will work as well

Hey @TomaKavi 

You can create the column using the DAX bellow:

YearQuarter_LastYear = [date].[Year]-1 &"/Q" & [date].[QuarterNo]

Kind Regards,
Marcel

maybe I am doing something wrong, but this wont work.

Are you creating a Column? You need create a New Column in table date instead of a measure.

And, in instead of [date] you should use the name of your date column.
