How to calculate measure with the development of active cases depending on the calendar table?

[MarcLykke]

Hi everyone

I am trying to calculate a measure that shows me the number of active cases in a given timeperiod.

Table 1 includes all cases

Case ID	Start date	End date	Status
1	15/01/2020		Active
2	04/10/2020	10/11/2021	Closed
3	03/05/2019	04/05/2020	Closed
4	20/10/2021		Active

I have created a relationship to a calendar-table based on the start date and end date in table 1. The relationship between calendar date and start date is active an the relationship between calendar date and end date is not.

Date	Year	Month	Week	Number of months ago	Number of weeks ago
xx	xx	xx	xx	xx	xx

I am trying to calculate a measure that allows me to compare the number of active cases now with the number of active cases the same time last year.

The visualization should look like this:

Case Group	Active cases (now)	Active cases (12 months ago)
Case Group 1	xx	xx
Case Group 2	xx	xx
Case Group 3	xx	xx
Case Group 4	xx	xx

Can anyone help me create this calculated measure?

Hi @MarcLykke 

Maybe you can try these two measures.

Active cases (now) =

VAR CountAct =

    CALCULATE (

        COUNT ( Table1[Start date] ),

        Table1[End date] > MAX ( 'calendar-table'[Date] )

            || Table1[Status] = "Active"

    )

RETURN

    IF ( ISBLANK ( CountAct ), 0, CountAct )

Active cases (12 months ago) =

VAR MinDate =

    MIN ( 'calendar-table'[Date] ) --Min Date in current period

VAR MaxDate =

    MAX ( 'calendar-table'[Date] ) --Max Date in current period

VAR PrevYearMinDay =

    DATE ( YEAR ( MinDate ) - 1, MONTH ( MinDate ), DAY ( MinDate ) ) --Min Date 12 months ago

VAR PrevYearMaxDay =

    DATE ( YEAR ( MaxDate ) - 1, MONTH ( MaxDate ), DAY ( MaxDate ) ) --Max Date 12 months ago

VAR count_ =

    CALCULATE (

        COUNT ( Table1[Start date] ),

        FILTER (

            'calendar-table',

            'calendar-table'[Date] >= MinDate

                && 'calendar-table'[Date] <= MaxDate

        ),

        ( Table1[Start date] < PrevYearMaxDay

            && Table1[End date] > PrevYearMaxDay )

            || Table1[Status] = "Active"

    )

RETURN

    IF ( ISBLANK ( count_ ), 0, count_ )

Then, the result should look like this:

@MarcLykke , I have blog on similar topic, see if that can help

https://community.powerbi.com/t5/Community-Blog/HR-Analytics-Active-Employee-Hire-and-Termination-tr...

Check the file for last year

example

Hire = CALCULATE([Employees], USERELATIONSHIP('Date'[Date], Emp[Start Date]))
Teminated = CALCULATE([Employees], USERELATIONSHIP('Date'[Date], Emp[End Date]), not (ISBLANK(Emp[End Date])))

Cumm Hire 1Year Back = CALCULATE([Hire], FILTER(ALL('Date') , 'Date'[Date] <= maxX('Date',DATEADD( 'Date'[Date],-1,year))))
Teminated Hire 1Year Back = CALCULATE([Teminated], FILTER(ALL('Date') , 'Date'[Date] <= maxX('Date',DATEADD( 'Date'[Date],-1,year))))
Current 1 Year Back = [Cumm Hire 1Year Back] -[Cumm Termination 1 year Back]
