MTBF implementation for Service Now

Hi All,   I am stuck in a situation where I have service Now (SNOW) data for P1,P2 and want to calculate MTBF based upon the assignment group.But confused about the situation when we have only one ...

    Hi,

     

    In my case the above solution did not work.I tried with another solution.

     

    I created a Row count column as below which groupe the data based upon the Assignment group and priority and gives the count of this .

     

    Row_counts = CALCULATE(COUNTROWS('INC Overview'),ALLEXCEPT('INC Overview','INC Overview'[Priority],'INC Overview'[Assignment group]))

     

    then I created another column let say Avg_MTBF which calculated the time between two failure of incidences and also cover those cases where we recieved only one incidence (in that case it will give the difference between today date and the day when it was occurred.)

     

    Avg_MTBF = If(([Row_counts]>1 && [2nd_highestvalue] <>BLANK()), DateDiff([2nd_highestvalue],[Created],DAY),
    IF([Row_counts]=1 && [2nd_highestvalue] =BLANK(),ABS(DateDiff(TODAY(),[Created],DAY)),0))

Assuming second higher last value is blank if there is only one

MTBFCount = VAR CompareDate = IF([2nd_highestvalue],max([2nd_highestvalue]),TODAY()) RETURN
If((MAX([Created]) && max([Priority])="1 - Critical" ||Max([Priority])="2 - High" ), DateDiff(CompareDate,MAX([Created]),DAY),0)

    Hi,

     

    Really thanks for your prompt help.

    However when I am using this as a cal measure then its giving me the below errorcalc_measure errorand when I am trying to create a calc column then it is calculating all the values zero;which make no sense to me.

     

    Please can you suggest what could be the best way to handle this.

      Sorry Saines your second highest measure returned a distinct value. Just wrap the test for the second highest value in a max or any other aggregate function in both the terms of the VAR MAX([2nd_highestvalue]),

      The reason it didn’t work as a calc column is that the filter context is limited to that row unless you use EARLIER or something to expand it so there is never a second higher at value for a single row.
