Rolling subtraction by quarter

I have the total number (108) and i want to subtract it with the value i have every quarter. (I can have the total number as a Column or as measure.) My problem is that I want to use the "Count by quarter", which is giving me the total amount of items that need to be subtracted. The way the report is builded, i have the same number for every record. What i want to have at the end is
Total = 108

Q4 2022 = 7
New Total = 108-7 = 101
Q1 2023 = 17
New total = 101-17= 84

etc
Any idea how can i do it with DAX or some other method?

Hi @Mr_Indy ,

We need a column like [Index] or [YearQuarter] to sort your [QT] column. Here I suggest you to create a DimDate table by dax.

``````DimDate =
CALENDAR ( DATE ( 2022, 01, 01 ), DATE ( 2023, 12, 31 ) ),
"Year", YEAR ( [Date] ),
"Month", MONTH ( [Date] ),
"Quarter", QUARTER ( [Date] ),
"QT",
"Q" & ""
& FORMAT ( [Date], "Q YYYY" ),
"QY",
YEAR ( [Date] ) * 100
+ QUARTER ( [Date] )
)``````

Relationship:

Then you can try this code to create a calcualted column.

``````Rolling subtraction by quarter =
VAR _STEP1 =
SUMMARIZE (
ALL ( 'Table' ),
'Table'[Burndown],
'Table'[Count by quarter],
'Table'[QT],
"QY", CALCULATE ( MAX ( DimDate[QY] ) )
)
VAR _STEP2 =
_STEP1,
"Rolling subtraction by quarter",
108
- SUMX ( FILTER ( _STEP1, [QY] <= EARLIER ( [QY] ) ), [Count by quarter] )
)
RETURN
SUMX (
FILTER ( _STEP2, [QT] = EARLIER ( 'Table'[QT] ) ),
[Rolling subtraction by quarter]
)``````

Result is as below.
