Calculated Columns

[wes-shen-poal]

Hi there,

I am a little stuck in creating Calculated Columns which are column H and column I in screenshot below for any given VehicleID (Column A).

I currently have Columns A:G in my 'VMS VehicleEvent' data table.

Can someone kindly provide me the DAX formula I need to calculate:

1) Column H, which takes the Event Name (column E) of the Latest Vehicle Event ID (column G)

2) Column I, which take the LocalEventDate (column F) of the Latest Vehicle Event ID (column G)

Once I have column I, I can then calculate a measure Active Dwell Time (column J) which is column I minus column C.

Thanks in advance for your help

Wes

@wes-shen-poal if you calculating it at a column level then you should just be able to do a date diff?  maybe i am not understanding why you need to find column i, are they not in the same row?

Hi @vanessafvg

Thanks for looking into this for me.

I need to find column I because once I can isolate the Latest Event Date from the other Event Dates within a column (i.e. column I) for each Vehicle ID, I will calculate the Dwell Time (which = Latest Event Date minus Vessel Depart Date) for each Vehicle ID. And then I can calculate the average Dwell Time of all Vehicle IDs.

Hope that makes sense.

Thanks,
Wes

Hi @wes-shen-poal

You could try these two formulas as calculated columns. (The VehicleEventID should be unique)

ColumnH =
CALCULATE (
    VALUES ( Table1[Event Name] ),
    FILTER (
        ALL ( Table1 ),
        'Table1'[VehicleEventID] = EARLIER ( 'Table1'[Latest Vehicle Event ID] )
    )
)

ColumnI =
CALCULATE (
    VALUES ( Table1[LocalEventDate] ),
    FILTER (
        ALL ( Table1 ),
        Table1[VehicleEventID] = EARLIER ( Table1[Latest Vehicle Event ID] )
    )
)

Best Regards!
