Incorrect Previous month value calculation

[Uzi2019]

Hi Community,

I am trying to create previous month values. Everything is working as expected only issue is last date in Database is 5th April 2021 but when I select Date range slicer from 1st to 4th April so it gives me correct prevoius month value. BUT when I select date range from 1st April to 5th April so it gives me whole March value in previous measure.

I want it to give me 1st to 5th March value in my previous measure when I select date range from 1st to 5th April.

I don't know why it's behaving like this.

Previous Sales = CALCULATE(SUM(DataTable[Sales]),DATEADD('Calendar'[Date],-1,MONTH))

Can anyone please help me in this?

Hi @Uzi2019 ,

Did you create a relationship between the two tables?

Hi @Syndicate_Admin ,

I create the following sample data, and then create a measure.

Ventas anteriores = 
var MonthEnd = 
    CALCULATE(
        SUM('DataTable'[Sales]),
        DATEADD( 'Calendar'[Date], -1, MONTH )
    )
var Month = 
    CALCULATE(
        SUM('DataTable'[Sales]),
        FILTER(
            ALL('DataTable'),
            'DataTable'[Date] <= EDATE( MAX('Calendar'[Date]), -1 )
            &&'DataTable'[Date] >= EDATE( MIN('Calendar'[Date]), -1 )
        )
    )
var Result = 
    IF(
        MAX('Calendar'[Date]) = EOMONTH( MAX('Calendar'[Date]), 0 ), 
        MonthEnd, 
        Month
    )
return Result

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.

@Syndicate_Admin , You can try like example

MTD QTY forced=
var _max = today()
return
if(max('Date'[Date])<=_max, calculate(Sum('order'[Qty]),DATESMTD('Date'[Date])), blank())
//or
//calculate(Sum('order'[Qty]),DATESMTD('Date'[Date]),filter('Date','Date'[Date]<=_max))
//calculate(TOTALMTD(Sum('order'[Qty]),'Date'[Date]),filter('Date','Date'[Date]<=_max))

LMTD QTY forced=
var _max = date(year(today()),month(today())-1,day(today()))
return
if(max('Date'[Date])<=_max, CALCULATE(Sum('order'[Qty]),DATESMTD(dateadd('Date'[Date],-1,year)),'Date'[Date]<=_max), blank())
//OR
//CALCULATE(Sum('order'[Qty]),DATESMTD(dateadd('Date'[Date],-1,year)),'Date'[Date]<=_max)
//TOTALMTD(Sum('order'[Qty]),dateadd('Date'[Date],-1,year),'Date'[Date]<=_max)

LYMTD QTY forced=
var _max = date(year(today())-1,month(today()),day(today()))
return
if(max('Date'[Date])<=_max, CALCULATE(Sum('order'[Qty]),DATESMTD(dateadd('Date'[Date],-1,year)),'Date'[Date]<=_max), blank())
//OR
//CALCULATE(Sum('order'[Qty]),DATESMTD(dateadd('Date'[Date],-1,year)),'Date'[Date]<=_max)
//TOTALMTD(Sum('order'[Qty]),dateadd('Date'[Date],-1,year),'Date'[Date]<=_max)

Hi, @Uzi2019 

If it is OK with you, please share your sample pbix file, then I can try to look into it and come up with a fixed result. 

Thank you.
