Using a Slicer to filter by operation result between to specific dates

[jfdacovich2022]

Hi ! We are trying to solve a problem with power bi but we are kinda blocked. Do you know how we can solve the following example being it using Dax, or with another method.

We have a set of identifiers with one value per day and we want to calculate dynamically, by selecting two dates as filter, a mathematical operation between the value for both dates for each of the components.

Example

Component 1  -  date 1 - value 1

Component 2  -  date 1 - value 2

Component 3  -  date 1 - value 3

Component 1  -  date 2 - value 4

Component 2  -  date 2 - value 5

Component 3  -  date 2 - value 6

Component 1  -  date 3 - value 7

Component 2  -  date 3 - value 8

Component 3  -  date 3 - value 9

Component 1  -  date 4 - value 10

Component 2  -  date 4 - value 11

Component 3  -  date 4 - value 12

We select as filters date 2 and date 4 getting

Component id  - date a - date b - value date a - value date b - operation

Component 1  -  date 2 - date 4 - value 4         - value 10       - (value 4 + value 10)

Component 2  -  date 2 - date 4 - value 5         - value 11       - (value 5 + value 11)

Component 3  -  date 2 - date 4 - value 6         - value 12       - (value 6 + value 12)

We need to do this as we need to filter the dashboard for the components where the operation results meet certain criteria between the specific dates.

Thanks in advance!!

Hi  @jfdacovich2022 ,

I created some data:

Here are the steps you can follow：

1. Create measure.

Measure =
var _mindate=
MINX(ALLSELECTED('Table'),[Date])
var _maxdate=
MAXX(ALLSELECTED('Table'),[Date])
return
SUMX(FILTER(ALL('Table'),
'Table'[Date]=_mindate&&'Table'[Component]=MAX('Table'[Component])),[value])
+
SUMX(FILTER(ALL('Table'),
'Table'[Date]=_maxdate&&'Table'[Component]=MAX('Table'[Component])),[value])

2. Result:

Operation = 
var DateASelected = SELECTEDVALUE('Dates A'[Date A] )
var DateBSelected = SELECTEDVALUE('Dates B'[Date B] )
var ShouldCalculate = DateASelected <> DateBSelected
var Result =
    if( ShouldCalculate,
        sumx(
            distinct( Components[Component] ),
            var DateAValue =
                CALCULATE(
                    SELECTEDVALUE( Components[Value] ),
                    Components[Date] = DateASelected
                )
            var DateBValue =
                CALCULATE
                    SELECTEDVALUE( Components[Value] ),
                    Components[Date] = DateBSelected
                )
            var ShouldCalculate = 
                not ( isblank( DateAValue ) || ISBLANK( DateBValue ) )
            var Output = 
                if( ShouldCalculate, DateBValue + DateAValue )
            return
                Output
        )
    )
return
    Result
