Post ProdigyDate Difference Between two columns and rows
Hi, I'm trying to create a formula which will display the difference between The End Date and the Start Date. This is showing how long it took to start a process after finishing one. In the case ...
michael_knight , Try a new column like
Column = var _max1 = maxx(FILTER('Table',[ID] =EARLIER([ID]) && [Start Date] <EARLIER('Table'[Start Date])),[Start Date]) var _max = maxx(FILTER('Table',[ID] =EARLIER([ID]) && [Start Date] =_max1),[End Date] ) return if(ISBLANK(_max), BLANK(), DATEDIFF(_max,[Start Date],DAY))

Post ProdigyHi amitchandak
Thank you for the reply. That's brilliant but one thing which I forgot to mention, if there is two processes on going, it must displace the earlier version. For example, for ID #3
| ID | Start Date | End Date | Expected Outcome |
| 1 | 05/05/2021 | 23/05/2021 | 0 |
| 1 | 15/06/2021 | 23 | |
| 2 | 25/03/2021 | 0 | |
| 3 | 02/07/2021 | 06/07/2021 | 0 |
| 3 | 17/07/2021 | 20/07/2021 | 11 |
| 3 | 29/07/2021 | 9 | |
| 3 | 05/08/2021 | ||
| 4 | 09/09/2021 | 0 | |
| 5 | 25/09/2021 | 27/09/2021 | 0 |
| 5 | 15/10/2021 | 20/10/2021 | 18 |
There are two ongoing processes, it should only display the date difference for earliest version with the latest version being left blank
