DATEDIFF between Rows
Hello,
I have a question about how to calculate datediff between rows. I have dataset like below:
| Trackingtocken | createdon |
| 1 | 01.08.2018 08:00 |
| 1 | 01.08.2018 08:01 |
| 1 | 01.08.2018 08:12 |
| 1 | 01.08.2018 08:14 |
| 1 | 01.08.2018 08:15 |
| 1 | 01.08.2018 10:31 |
What I need is a calculated column where datediff (MIN or HOUR) between each row is calculated (from the very beginning).
Something like the outcome below (based on my example):
| Datediff |
0 1 11 2 1 .... |
Could you please help me with that?
Regards
Magomed.
HI, Magomed
After my test, you could do these follow my steps as below:
Step1:
Add a group rank column
group rank = RANKX(FILTER(Table1,Table1[Trackingtocken]=EARLIER(Table1[Trackingtocken])),Table1[createdon],,ASC)
Step2:
Use EARLIER Function add a datediff column
Datediff = DATEDIFF(CALCULATE(MAX(Table1[createdon]),FILTER(Table1,Table1[Trackingtocken]=EARLIER(Table1[Trackingtocken])&&Table1[group rank]=EARLIER(Table1[group rank])-1)),Table1[createdon],MINUTE)
Result:

See my article on Mean Time Before Failure (MTBF) which uses EARLIER: http://community.powerbi.com/t5/Community-Blog/Mean-Time-Between-Failure-MTBF-and-Power-BI/ba-p/339586
