Compare between two timestamp with condition

[Anonymous]

Hello ,

I have this table and i need to compare between the last date (Field2 ) with Field3 (X) and the first row who contain SSE in Field 3

Example :  i need to do for this picture 2 calculs : 

First one : it needs to detect Field3 = SSE so it will retrieve the date 02:45 and compare it with the Row X5 (the last row when Field3 = X) 

So : 02:45 - 00:26 = 02:19

and repeting this condition for all the file 

example 2 : 2:20 - 00:10 

Thank you for all

Hi, @Anonymous 

Thanks for your sample data first!

Here are the steps you can refer to :
(1)This is my test data:

(2)We can create a calcualted column like this:

Column = var _sse_date =  IF([Field3]="SSE" , [StartDate] ,  BLANK())
var _t = FILTER('Table','Table'[StartDate]<_sse_date && 'Table'[Field3]= "X")
var _max_startdate =  MAXX(_t, [StartDate])
var _lastdate= MAXX(FILTER(_t,[StartDate] = _max_startdate) , [LastDate])
return
_sse_date-_lastdate

Then we can get the result is as follows:

If this method does not meet your needs, you can provide us with your special sample data and the desired output sample data in the form of tables, so that we can better help you solve the problem. (You can also upload you sample .pbix [without sensitive data] to the OneDrive and share with the OneDrive link to me ! )

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!
