Extract the Last bus-station and back to Garage

[Anonymous]

Hello Helpful coummunity,

I used the below DAX to compute when a bus leaves the Garage to the first busstop.  Now trying to do the same for Last busstop to back to Depot. 

Helpful information: I have flag for the last busstop (Isendplace), and a flag when the bus enters the garage (TransType = "Gateentry"). Usually the Gateentry is nextrow after the lastbusstop.

IF('Fact vwPunctuality'[PreviousTransType] = "GateExit",

CALCULATE(
FIRSTNONBLANK('Fact vwP'[Dim vwPlace.PlaceName],1),
FILTER('Fact vwP',
'Fact vwP'[TrafficDateKey] = EARLIER('Fact vwPunctuality'[TrafficDateKey]) &&
'Fact vwPunctuality'[VehicleKey] = EARLIER('Fact vwPunctuality'[VehicleKey]) &&
'Fact vwPunctuality'[BlockSequence] = EARLIER('Fact vwPunctuality'[BlockSequence]) -1)) & " - " & RELATED('Dim vwPlace'[PlaceName])).

Dax Result = "Michael Gararge - Saint Hospital"

Hi @Anonymous ,

You may try the DAX as below.

IF('Fact vwPunctuality'[TransType] = "Gateentry",

CALCULATE(

LASTNONBLANK('Fact vwP'[Dim vwPlace.PlaceName],1),

FILTER('Fact vwP',

'Fact vwP'[TrafficDateKey] = EARLIER('Fact vwPunctuality'[TrafficDateKey]) &&

'Fact vwPunctuality'[VehicleKey] = EARLIER('Fact vwPunctuality'[VehicleKey]) &&

'Fact vwPunctuality'[BlockSequence] = EARLIER('Fact vwPunctuality'[BlockSequence]) +1)) & " - " & RELATED('Dim vwPlace'[PlaceName]))

If I misunderstood it, could you please share your sample data and desired output screenshots for further analysis? You can also upload sample pbix to OneDrive and post the link here. Do mask sensitive data before uploading.

Thank @v-xicai  for your time 

Above the screenshot of the data, the desired output is Blocksequence 169 - 170  (LastBustop - GateEntry)
