Time between two dates based on criteria

[Anonymous]

Hello! 

I have a table of ticket data where I for each critical ticket need to calculate the time since the last critical ticket was registered.
Been trying to solve this for a few hours now without success.

Basically: If Priority = Critical, calculate time between regdate and previous critical tickets' regdate (for each row). The goal is to calculate the average time between critical tickets being registered.

Any help would be greatly apreciated!

Hi Jowh, 

Not sure about your use case, is it something like below:

here comes the code for the calculated column:

Duration =

VAR CurrentDate = 'Table'[Date]

VAR TABLE1 =

    CALCULATETABLE(

        'TABLE',

        FILTER ('Table', 'Table'[Priority]="Yes"),

        FILTER ('Table', 'Table'[Date]>CurrentDate)

    )

VAR MinDate =

    MINX (

         TABLE1,

        'Table'[Date]-CurrentDate)

RETURN

    IF (

        'Table'[Priority]="Yes",

        INT( MinDate)

    )

Hello and thank you! 

It is something similar but in the reverse order I suppose. Latest date should show the previous max date with Priority if that makes sense. Also presented in hours or minutes but I think I could figure that part out myself in worst case 🙂

Good Luck!

Not really getting this to work 😞 Tried to change to the following:

Time Since Last Critical = 
VAR CurrentDate = Issues[DATE_CREATED]
VAR TABLE1 =
    CALCULATETABLE(
        'Issues',
        FILTER ('Issues', 'Issues'[ISSUE_PRIORITY]="Critical"),
        FILTER ('Issues', 'Issues'[DATE_CREATED]<CurrentDate)
    )
VAR MinDate =
    MAXX( 
         Issues,
        Issues[DATE_CREATED]-CurrentDate)
RETURN
    IF (
        Issues[ISSUE_PRIORITY]="Critical",
        INT( MinDate),blank()
    )

I don't really understand the MinDate logic though (tried both MINX and MAXX)

The first argument of MINX shall be the filtered table - Table1, instead of the native table - Issues.

MINX is to scan Table1 and get the immediate last date tagged "Critical."
