DATEADD not working in Matrix

[Anonymous]

I created a measure that shows revenue from the 12 months before the last 12 months using DATEADD function.  I put it in a MATRIX and it works fine when there are no row or column headings added to the MATRIX.  (See below)

However, when I try to add a dimension to rows, it gives me the following error:

Does anyone know how to fix this?  Thanks in advance!

Hi,

According to your description, i create a sample to test:

Then create a date slicer table:

Date Slicer = DISTINCT(SELECTCOLUMNS('Table',"Date",'Table'[Date]))

Then try this measure:

Measure = 
var a = SELECTEDVALUE('Date Slicer'[Date])
return
CALCULATE(SUM('Table'[accrual_revenue]),DATESBETWEEN('Table'[Date],DATE(YEAR(a)-2,MONTH(a),DAY(a)),DATE(YEAR(a)-1,MONTH(a),DAY(a))))

When choosing one date in date slicer, the result shows the total revenue from the 12 months before the last 12 months based on the date selected:

Tips: In this case, i add a defined filter to the table visual to show the result more obviously.

Here is my test pbix file:

Hope this can help.

For all such calculation use a date calendar and join the Date of Calendar with your date.

Something like

Last YTD Sales = CALCULATE(sum('PL lines'[PL Line.1]),DATESYTD(dateadd('Date'[Date],-1,Year),"12/31"))
Last YTD complete Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(ENDOFYEAR(dateadd('Date'[Date],-1,Year)),"12/31"))

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :

@amitchandakThanks.  I do have a date calendar thats joined to my table date.  I believe your formula examples do not pull prior 12 months before the last 12 months.

This formula works fine except when a row dimension is added to the matrix.

Prior 12 mo Rev = Calculate(sum('TKD'[accrual_revenue]),DATESINPERIOD(TKD[Date],ENDOFMONTH(DATEADD(TKD[Date],-12,MONTH)),-12,MONTH))

Yes when you view by few dimension not all dates world be there, Try if one of 2 works

Prior 12 mo Rev = Calculate(sum('TKD'[accrual_revenue]),DATESINPERIOD(Date[Date],ENDOFMONTH(DATEADD(TKD[Date],-12,MONTH)),-12,MONTH))
Prior 12 mo Rev = Calculate(sum('TKD'[accrual_revenue]),DATESINPERIOD(Date[Date],ENDOFMONTH(DATEADD(Date[Date],-12,MONTH)),-12,MONTH))

@amitchandakUnfortunately, they didn't work.  I think it's the dateadd piece that breaks it. 😞

I have one doubt, your calendar min date is less than the min date of the TKD table. Just check.

If not so, Create a sample where you can reproduce and share.
