Simplifying a code using the "earlier" function
Hello,
I would like to filter the departure and arrival times of the cranes. I have a database with the times of the different cranes mixed together and with this code it calculates the intermediate time i.e. arrival time of the 1st crane - next departure time for the 1st crane.
The code sorts the filtered times by bridges but if I have a lot of lines this code does not work anymore because of the "earlier" function which is very greedy for the pc, how to simplify this code please?
Anonymous , Sorry, Try like
CALCULATE(MIN('Bridge Hall 3 M'[DateHour_Origin]),FILTER('bridge Hall 3 M','bridge Hall 3 M'[Number_bridge]=EARLIER('bridge Hall 3 M'[Number_Pont])
&&'bridge Hall 3 M'[Date Rank] = EARLIER('bridge Hall 3 M'[Date Rank]) +1 ))-'bridge Hall 3 M'[Datehour_Arrival])

Anonymous , Create two columns
Date Rank = rankx(Filter('bridge Hall 3 M' , [Number_bridge] = EARLIER('bridge Hall 3 M'[Number_Pont]) ), 'bridge Hall 3 M'[DateHour_Origin],,asc, dense)
Col2 =
CALCULATE(MIN('Bridge Hall 3 M'[DateHour_Origin]),FILTER('bridge Hall 3 M','bridge Hall 3 M'[Number_bridge]=EARLIER('bridge Hall 3 M'[Number_Pont])
&&'bridge Hall 3 M'[Date Rank] = EARLIER('bridge Hall 3 M'[Date Rank] +1 )))-'bridge Hall 3 M'[Datehour_Arrival])Hi amitchandak,
I get an error message "the first argument of earlier is not a valid column reference in the previous row context." for EARLIER('bridge Hall 3 M'[Date Rank] +1
I just passed but I don't get the right values...
An example of the application I need:
Deck 2 datetime departure: 20/07/22 01:06:23 dtatetime arrival: 20/07/22 01:07:23
Deck 3 datetime departure: 20/07/22 03:00:26 datetime arrival: 20/07/22 03:07:26
Deck 1 start time: 20/07/22 02:00:00 finish time: 20/07/22 02:04:05
Deck 2 datetime departure : 20/07/22 03:08:00 dtatetime arrival : 20/07/22 03:09:55The code must take into account the bridge number, the departure time after 03:08:00 minus the arrival time before 01:07:23 = 2:00:37

&&'bridge Hall 3 M'[Date Rank] = EARLIER('bridge Hall 3 M'[Date Rank]) +1 ))-'bridge Hall 3 M'[Datehour_Arrival])I fiddled around a bit and ended up with the values I wanted, great, thanks a lot!
