Date Range From Input Parameters in Calculate DAX

[BriefStop]

Date	Value
6/13/2019	3
6/13/2020	4
6/13/2021	7

I have a table of dates and values and I want to find the difference between the sum of values of a current period and a previous period which both are filtered on the same date column. Essentially I would have one sum of value that is filtered normally with a regular slicer using date and a second sum of a value that needs to be specified separately.

The final result would look like this:

Previous Period(Measure) - 6/13/2019 - 6/13/2020: 7

Current Period(Measure) - 6/13-2020 - 6/13/2021: 11

Difference between periods(Measure): 4

I plan to use a CALCULATE to sum the values and then apply the date filter to the previous period but I am not sure how I can set up an input parameter to do a date range just like if I was simply filtering for date.

Currently:

Only thing I can think of is setting up two custom input parameter tables for the Start Date and End Date and then filtering them in calculate as CALCULATE(SUM(Value), AND(Date > Start Date, Date < End Date)). This hasn't worked so far though and the filter looks very different from my regular date slicer.

Is there another way to do this so that it looks like a regular date slicer? How do I filter on a date range?

Hi @BriefStop ,

I have created a simple sample , please refer to my pbix file to see if it helps you.

Create 2 measures.

Previous Period(Measure) =
VAR _1 =
    EDATE ( MAX ( 'Table'[Date] ), -12 )
VAR _2 =
    CALCULATE (
        SUM ( 'Table'[Value] ),
        FILTER ( ALL ( 'Table' ), 'Table'[Date] = _1 )
    )
VAR _3 =
    IF ( _2 = BLANK (), BLANK (), _2 + MAX ( 'Table'[Value] ) )
RETURN
    _3

Measure =
VAR _1 =
    EDATE ( MAX ( 'Table'[Date] ), 12 )
VAR _2 =
    SUMX (
        FILTER ( ALL ( 'Table' ), 'Table'[Date] = _1 ),
        [Previous Period(Measure)]
    )
VAR _3 = _2 - [Previous Period(Measure)]
RETURN
    IF ( _2 = BLANK () || [Previous Period(Measure)] = BLANK (), BLANK (), _3 )
