Datediff start to end in relationship orderid

[lifesafari]

Hello, i have this file where i have this info:

• date/time
• number 
• orderid 

I need calculate different, for each orderid, from start time (have number 0 on colum number) and end (have mx number for this orderid on column number) in minutes. 


I try to create two colum:

1) Start Date 

DataInizio = IF([Numero] = 0, [Data e ora creazione], BLANK())

2) End Date

DataFine = IF([Numero] = MAXX(FILTER(AxTable1, [Nr. Commessa] = EARLIER([Nr. Commessa])), [Numero]), [Data e ora creazione], BLANK())

3) DateDiff

Diff = DATEDIFF(AxTable1[DataFine],AxTable1[DataInizio],MINUTE)

But have blank on column 3 😞

Hi @lifesafari ,

Can you share sample data and the results you are hoping for? Show it as a screenshot or excel. Or a sample pbix after removing sensitive data. We can better understand the problem and help you.

Hello @lifesafari,

Can you please try this approach:

DateDiffMinutes = 
VAR MaxNumberPerOrder = SUMMARIZE(YourTable, YourTable[orderid], "MaxNum", MAX(YourTable[number]))
VAR StartDate = MINX(FILTER(YourTable, YourTable[Numero] = 0), YourTable[Data e ora creazione])
VAR EndDate = MAXX(FILTER(YourTable, YourTable[orderid] IN SELECTCOLUMNS(MaxNumberPerOrder, "OrderID", YourTable[orderid]) && YourTable[Numero] = [MaxNum]), YourTable[Data e ora creazione])
RETURN
DATEDIFF(StartDate, EndDate, MINUTE)
