Create a custom column with value from another table

[driplytics]

Hi, i need help with this.

i have a flight data table with column name AirportFrom  and another AirportTo, columns has IATA code(Airport Code). 

my Goal is to show the Flight routes on a FLow map Visual.

To do this, i would like to use the Airport name instead of Airport Code. 

so, i overlayed a Dataset that has the Airportcode, Airport Names, Longitudes and Latitudes.

and Built a data Model with it.

then i tried to Create two custom columns named AirportOrigin and Airport Destination in the flight Dataset to retrieve the    Airport Names from the Overlayed table.

but i've got it all wrong with this.

My wrong solution

I would be so grateful, if i can solve this. 

probably in a more efficient way.

Hi @driplytics 
What dax code did you use? which error did you get? which column connects the two tables?

[driplytics]

thank you @tamerj1 for ypur response.

Here's Dax i used to Create the 2 Custom columns

AirportOrigin = CALCULATE(

LOOKUPVALUE('Airport Data'[name],'Dataset'[AirportFrom],SELECTEDVALUE('Dataset'[AirportFrom]),

'Dataset'[AirportFrom])

Airport Destination = CALCULATE(LOOKUPVALUE('Airport Data'[name],'Dataset'[AirportTo],SELECTEDVALUE('Dataset'[AirportTo]),'Dataset'[AirportTo]))

This is the Error i got.

Here are the connected column on both tables.

My Goal is to retrieve the Airport Name from the Airport Data and store it in a custom column created on the Dataset table. 

for Reference here's the link to my Datasets. 

Dataset : https://www.dropbox.com/s/3i8s6uwqdg2qnmy/Airlines.csv?dl=0

Airport Data : https://www.dropbox.com/scl/fi/av8hmkj5dl47n9zacdzov/US-Airport-codes.xlsx?dl=0&rlkey=bre70loq2nu22x...

thanks @tamerj1 , i think you are close to the solution.

but instead of returning same Iata_code (Eg in the pics below, ATL is an Airport code), i want the name returned (Hartsfield Jackson Atlanta International Airport) on the custom columns.

Hi, @driplytics 

Delete the relationship/add a new seperate table and then try calculated columns as below:

AirportOrigin = LOOKUPVALUE('Airport Data'[name],'Airport Data'[iata_code],'Dataset'[AirportFrom])

Airport Destination = LOOKUPVALUE('Airport Data'[name],'Airport Data'[iata_code],'Dataset'[AirportTo])
