Result last 90 days vs Result between 90 and 180 days

[FredLEGUEN]

Hi,

I have a table with the number of days to resolve a ticket (Date close ticket - Date open ticket)

I want to calculate the average number of days for the last 90 days.

I have tried with DATESINPERIOD([Date],MAX([Date],-90,DAY)

Also PARALLELPERIOD([Date],0,QUARTER)

But none of these techinique return what I want

And also, how do you return the result for the range between -90 days and -180 days?

Thanks

Hi @Anonymous ,

if you use this sample model

 

and the following measures:

Avg Days = AVERAGE(DaysforTicket[DayforTicket])

Avg Last 90 Days =

VAR MaxDate = MAX('DaysforTicket'[Date])

RETURN

CALCULATE([Avg Days],

          'DaysforTicket'[Date]<= MaxDate && 'DaysforTicket'[Date] > MaxDate -91

)

Avg Last 90-180 Days =

VAR MaxDate = MAX('DaysforTicket'[Date])

RETURN

CALCULATE([Avg Days],

          'DaysforTicket'[Date]<= MaxDate -90 && 'DaysforTicket'[Date] > MaxDate -180

)

you can get the following result:

With in your measure use below measure 

FILTER(ALL('Date'),[Date] >=startdt && [Date] <= enddt)
where startdt and and enddt will change based on the criteria 
0-90 days or 91 - 180 days
