Calculate Differance Between two dates, grouping by another field in data set.

In this dataset, I have rows of data that share the same 'PhaseID'. I want to calculate the differance (in days) between the first 'ScheduledStartDate' and the last 'ScheduledCompleteDate' for each row that shares the same 'PhaseID'.

 

For Example, for PhaseID 89578 the first ScheduledStartDate = 10/22/21 and the last ScheduledCompleteDate = 11/8/2021 so the differance would be 18 days. I also want to exclude weekends in the calculation.

 

Help is appreciated!

    Hi vincenardo 

    You can try this measure to get diff between ScheduledStartDate & ScheduledCompleteDate.

    diff = 
    var _min=CALCULATE(MIN('Table'[ScheduledStartDate]),ALLEXCEPT('Table','Table'[PhaseID]))
    var _max=CALCULATE(MAX('Table'[ScheduledCompleteDate]),ALLEXCEPT('Table','Table'[PhaseID]))
return 
    DATEDIFF(_min,_max,DAY)+1

    and if you want to exclude weekends in the calculation, then add a calendar table, and use the measure bellow

    diff = 
    var _min=CALCULATE(MIN('Table'[ScheduledStartDate]),ALLEXCEPT('Table','Table'[PhaseID]))
    var _max=CALCULATE(MAX('Table'[ScheduledCompleteDate]),ALLEXCEPT('Table','Table'[PhaseID]))
return 
    CALCULATE(COUNTROWS('Calendar'),DATESBETWEEN('Calendar'[Date],_min,_max),'Calendar'[Isweekday]<>7&&'Calendar'[Isweekday]<>1)

     result

    vincenardo , You can create a new column like

     

    Work Day = COUNTROWS(FILTER(ADDCOLUMNS(CALENDAR(Table[ShceduleStartDate],Table[ShceduleCompleted Date]),"WorkDay", if(WEEKDAY([Date],2) <6,1,0)),[WorkDay] =1))

     

    Business Days/ Workdays, with or without date table: https://youtu.be/Qv4wT8_P-AA
