Hi there! I need some assistance with calculating a time difference between values in the same column. I have seen some other posts on the same topic, but they are not similar enough to my issue that i have been able to use them.
I have this extract from a large dataset
| EVENTDATE_LOCAL | DATE/TIME | REPORT_TYPE | VOYNUM | POSITION | Position_Custom |
| 14.03.2024 22:00 | 14.03.2024 22:00 | Arrival | 132 | Arr. JEBEL ALI | JEBEL ALI |
| 17.03.2024 04:42 | 17.03.2024 04:42 | Arrival | 132 | Arr. ABU DHABI | ABU DHABI |
| 21.03.2024 09:00 | 21.03.2024 09:00 | Arrival | 132 | Arr. MUMBAI | MUMBAI |
| 29.03.2024 08:00 | 29.03.2024 08:00 | Arrival | 132 | Arr. SINGAPORE | SINGAPORE |
| 16.03.2024 23:54 | 16.03.2024 23:54 | Departure | 132 | Dep. JEBEL ALI | JEBEL ALI |
| 18.03.2024 05:30 | 18.03.2024 05:30 | Departure | 132 | Dep. ABU DHABI | ABU DHABI |
| 22.03.2024 17:30 | 22.03.2024 17:30 | Departure | 132 | Dep. MUMBAI | MUMBAI |
| 30.03.2024 10:48 | 30.03.2024 10:48 | Departure | 132 | Dep. SINGAPORE | SINGAPORE |
I would like to create a new column that calculates the time between Arrival and Departure if the VOYNUM and Position_Custom is the same. Would be great if anyone has any ideas!

Hi Anonymous ,
Create calculate column.
Time Difference = VAR CurrentRowDate = 'Table'[EVENTDATE_LOCAL] VAR CurrentVOYNUM = 'Table'[VOYNUM] VAR CurrentPosition = 'Table'[Position_Custom] VAR DepartureDate = CALCULATE( MIN('Table'[EVENTDATE_LOCAL]), FILTER( 'Table', 'Table'[VOYNUM] = CurrentVOYNUM && 'Table'[Position_Custom] = CurrentPosition && 'Table'[REPORT_TYPE] = "Departure" && 'Table'[EVENTDATE_LOCAL] > CurrentRowDate ) ) RETURN IF('Table'[REPORT_TYPE] = "Arrival" && NOT(ISBLANK(DepartureDate)), DATEDIFF(CurrentRowDate,DepartureDate,HOUR) / 24, BLANK() )If your Current Period does not refer to this, please clarify in a follow-up reply.

Thank you Clara
Unfortunately, I have a DirectQuery model and get the error message that the function CALCULATE is not allowed. I also tried to use the formula as a measure but it seems the issue is then that a single value for column 'EVENTDATE_LOCAL' in 'Table' cannot be determined. Not quite sure how to proceed.
