Calculating Month to month Change by month and partial days in the month

[cisyncllc]

my secnario is I am counting totals of previous month totals over current month totals but I only want to compare forexample Feb 1st -15th over Jan 1st - 15th.  I have Year filter, Month filter and Day Filter on my dashboard and by using samperiod calculation it works by year and month (full days) but when I start comparing by day its not working.

Count Current = distinctCOUNT(lwmain[inci_id])

****   Code previous= CALCULATE([Code Count_Distinct],  PARALLELPERIOD('Calendar'[Date], -1, MONTH))

Diff 4 = [Code Count_Distinct] - [Code Count4_4]

Month visual 

Visual when day filter is applied

Please help

Hi @cisyncllc ,

Here's my solution.

If your current month count measure is correct, simply use the PREVIOUSMONTH function.

PreviousMonthCount = CALCULATE([CurrentMonthCount],PREVIOUSMONTH('Calendar'[Date]))

You can check more details from my attachment.

@cisyncllc , Try like

_max can be today or selected date in slicer maxx(allselected('Date'),'Date'[date])

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)

Filters: "Day" is Day Number.
