Running Total (prior 3 fiscal years)

Marcus2 — Sat, 01 Feb 2025 15:03:35 GMT

Hi, how can I get 3 prior years from the FY selected. My goal is to select a single year (2024 in this example) and view data three years prior (with final aggregation month selected in a second slicer). Is there a DAX for this?

FY	Month	Value
2022	Oct	5
2022	Nov	5
2022	Dec	5
2022	Jan	5
2022	Feb	5
2022	Mar	5

Desired table result with FY2024 and Nov slicer selections:

Marcus2 , First create a measure to capture selected month and year

SelectedFY =
SELECTEDVALUE('Table'[FY])

SelectedMonth =
SELECTEDVALUE('Table'[Month])

Now create a measure to calculate on the basis of this

Sum3YearsPrior =
VAR CurrentFY = [SelectedFY]
VAR CurrentMonth = [SelectedMonth]
VAR PriorFY1 = CurrentFY - 1
VAR PriorFY2 = CurrentFY - 2
VAR PriorFY3 = CurrentFY - 3
VAR EndDate = DATE(CurrentFY, MONTH(DATEVALUE("1 " & CurrentMonth & " " & CurrentFY)), DAY(DATEVALUE("1 " & CurrentMonth & " " & CurrentFY)))
VAR StartDate = DATE(PriorFY3, MONTH(DATEVALUE("1 " & CurrentMonth & " " & PriorFY3)), DAY(DATEVALUE("1 " & CurrentMonth & " " & PriorFY3)))
RETURN
CALCULATE(
SUM('Table'[Value]),
DATESBETWEEN('Table'[Date], StartDate, EndDate)
)

Dont understand the your exact output what you are looking for.
I have assumed 3 scenario output. Below are the details

1) Lets you are looking for total aggegate value for 3 year's prior and same month.. For example, if you select 2025 in year slicer and sep in Month slicer. You want to sum up prior 3 years (2022,2023,2024) sep's value then below code will work

Total Aggregate Value = VAR _Selection = MAX( Data[FY] ) VAR _1stYr = _Selection - 1 VAR _2ndYr = _Selection - 2 VAR _3rdYr = _Selection - 3 VAR _tbl = UNION( ROW("@yr",_1stYr), ROW( "@yr",_2ndYr), ROW("@yr",_3rdYr) ) VAR _vtable = TREATAS( _tbl,Data[FY] ) VAR _Result = CALCULATE( SUM(Data[Value] ), _vtable ) RETURN _Result

2) If you want to show,, total value from 2022 sep to 2024 sep. The below is code

Full Data Value = SUMX( VALUES( Data[Index] ), VAR _endIndex = MAX( Data[Index] ) - 12 VAR _StarIndex = MAX( Data[Index] ) - 36 VAR _tbl = FILTER( ALL( Data ), Data[Index] <= _endIndex && Data[Index] >= _StarIndex ) VAR _check = COUNTROWS( _tbl ) VAR _Result = SUMX( _tbl,[Value] ) RETURN _Result )

3) if you want to only show only 3 years (2022 sep,2023 sep,2024 sep) data in a table visual..then check the below pbix file for steps. Page name -> Showdata.

Hope it helps

Hi Marcus2

I think you need to:

Capture the selected FY from a slicer.
Determine the three prior years dynamically.
Filter the data to include only the selected month up to the chosen month in all relevant years.

Please use this dax;

Filtered Value = VAR SelectedFY = SELECTEDVALUE('FY_Table'[FY]) -- Captures the selected fiscal year VAR SelectedMonth = SELECTEDVALUE('FY_Table'[Month]) -- Captures the selected month VAR StartFY = SelectedFY - 3 -- Compute three years prior RETURN CALCULATE( SUM('FY_Table'[Value]), -- Aggregating the values 'FY_Table'[FY] >= StartFY && 'FY_Table'[FY] < SelectedFY, -- Includes three prior years 'FY_Table'[Month] <= SelectedMonth -- Filters months up to the selected one )

If you want to display this filtered data in a table visual, create a calculated column instead of a measure.
If the fiscal year starts in a month other than January (e.g., July), adjust the FY logic accordingly.
