POWER BI - calculating durations
Hello
I have a table that contains Deal ID (unique value), date of deal, Activity ID (unique values) and date of activity. There is a one to many relationship between Deal ID and Activity ID.
I want to calculate the time between date of deal and date of activity, but only for the first completed activity of each deal.
Deal ID Date of deal Activity ID Date of activity
A 01/01/2019 1 06/01/2019
A 01/01/2019 2 03/01/2019
A 01/01/2019 3 15/02/2019
B 02/03/2019 4 04/03/2019
B 02/03/2019 5 08/03/2019
C 16/02/2019 6 25/02/2019
C 16/02/2019 7 20/02/2019
C 16/02/2019 8 21/02/2019
C 16/02/2019 9 28/02/2019
In the above example, Deal A has 3 associated activities, and Activity 2 was the first completed activity
Deal B has 2 associated activities, and Activity 4 was the first completed activity
Deal C has 4 associated activities, and Activity 7 was the first completed activity
The reason I'm asking is that we have a KPI that says any activity must be within 2 days of deal date - so I'm only interested on the first activity. Does that make sense?
RE: POWER BI - calculating durations
Hi Brett,
Thank you for the forum question.
To got the date of the first activity I created a column calculation in the many table (the table where you have the data above) see dax below. The dax will return the first date for each activity for each deal id. You then just need to calculate [FirstActivity]-[Date of Deal]
FirstACtivity = CALCULATE(MIN(Table1[Date of Activity]),FILTER(Table1,Table1[Deal Id]=EARLIER(Table1[Deal Id])))
I hope this makes sense.
Kind regards
