2021-07-09 MLA-4026 What-If Analysis does not properly display on some Unix platforms
2020-08-03 MLA-3950 Apply command does not run if used from a sub search
Workaround:
Use 
appendcols
command to append the column that will be returned from the subsearch to the savedsearch's columns, instead of assigning its value to a non-existing column in the savedsearch. Example: 
| inputlookup track_day.csv
| fit LogisticRegression fit_intercept=true "vehicleType" from "batteryVoltage" "engineCoolantTemperature" "engineSpeed" "lateralGForce" "longitudeGForce" "speed" "verticalGForce" into "example_vehicle_type"
makeresults count=50000
save as 
MLA3950
|savedsearch MLA3950 | appendcols \[| inputlookup track_day.csv | apply "example_vehicle_type" | table vehicleType]
This will append the 
vehicleType
column from the 
subsearch
to the 
savedsearch
columns.
