Hi,

I have created the quick measure to calculate the moving average with dynamic slicer. But facing column total error for the measure. Like it has to sum Jan to Dec data and show it in the column but column total only taking Dec month data everytime.

Example - Should be Oct+Nov+Dec = 75379+62685+26346 = 164410 But the total showing is 26346.

Please help me with the following issue

I am getting column total error and taking Matrix table 

Rows - Country,ProductCategory

Column - Month

I'm getting column total incorrect for Forecast(Blue) data.

Dax Formula (Quick Measure) - Product_Count rolling average =
IF(
ISFILTERED('Table_name'[dimdate]),
ERROR("Time intelligence quick measures can only be grouped or filtered by the Power BI-provided date hierarchy or primary date column."),
VAR __LAST_DATE = ENDOFMONTH('Table_name'[dimdate].[Date])
VAR __DATE_PERIOD =
DATESBETWEEN(
'Table_name'[dimdate].[Date],
STARTOFMONTH(DATEADD(__LAST_DATE, 'Moving Average'[Moving Average Value], MONTH)),
__LAST_DATE
)
RETURN
AVERAGEX(
CALCULATETABLE(
SUMMARIZE(
VALUES('Table_name'),
'Table_name'[dimdate].[Year],
'Table_name'[dimdate].[QuarterNo],
'Table_name'[dimdate].[Quarter],
'Table_name'[dimdate].[MonthNo],
'Table_name'[dimdate].[Month]
),
__DATE_PERIOD
),
CALCULATE(
SUM('Table_name'[Product_Count]),
ALL('Table_name'[dimdate].[Day])
)
)
)

Thanks!
