DAX lookup = merge queries?

Hi guys, please help me and explain ? I created a calculated column in DAX:


Route = LOOKUPVALUE(Manual[Route_full], Manual[Route], Trains[Route])
So in Trains I get Route_full column with no blank values.
Now in Power Query when I merge Trains with Manual (left outer) through Route column I get null values.
Not sure why, any thoughts?

Merge Queries can achieve similar goals to lookupvalue. Maybe provide sample tables and expected output, see if we can help you to make it.

@aleksandra_stan - Sample data would be good but I'm wondering about your setup here. Since you are using DAX for your Route column, that means it is a calculated column and that calculation occurs after Power Query does its work so I am wondering if the issue here is the order of operations? Would need sample data to recreate.
