CALCULATE function does not filter data

[SaiSpandana2811]

I am trying to use the CALCULATE function in DAX to find sum of income in last 12 months. The measure I am using is as below

Sub measures

Latest Month in Table = MAX(pbi_inc[yymm])
Samemonth_prev year = [Latest Month in Table] -100

Main DAX:

income_inc=
var lm = [Latest Month in Table]

var r12m = [ Samemonth_prev year]

return CALCULATE(SUM(pbi_inc[inc], pbi_inc[ic/cr] =1,pbi_inc[yymm] >=lm , pbi_inc[yymm] <=r12m)

The issue I am facing is the Calculate function is not filtering data for yymm. It filters data when I change the ic/cr value but not for yymm.

It works fine when I hardcode to something like 2112 but not when I use variables and submeasures.

I have compared the data types and spaces and all are compatible. All fields are taken from the same fact table

Can some one please help me?

Hi @SaiSpandana2811 ,

I think you can try to use the DATESINPERIOD function to quickly solve for the sum over the past period of dates. Refer to the following formula:

M_ =
CALCULATE (
    SUM ( 'Table'[Value] ),
    DATESINPERIOD ( 'Table'[Date], MAX ( 'Table'[Date] ), -12, MONTH )
)

Or create a date column and dynamically filter a date to find the sum over time.

M_1 =
CALCULATE (
    SUM ( 'Table'[Value] ),
    DATESINPERIOD ( 'Table'[Date], SELECTEDVALUE ( Tab_data[Date] ), -12, MONTH )
)

You may be overcomplicating things a bit. Read about the EDATE() function. Also, your comparators are the wrong way round.

Instead of 

pbi_inc[yymm] >=lm , pbi_inc[yymm] <=r12m

you should use

pbi_inc[yymm] <=lm , pbi_inc[yymm] >=r12m
