power query IF statement help

how to write a formula in powerbi for "if a column from my current table equals to a column in another table then its xxx if not xxx"?

I can't do conditional column becase the two columns are in two different tables.

I'm trying to use the custom column to do this. 

Any help would be appreacited

thanks!

Hi @fbostan1 ,

My Sample is as below.

Table1:

Table2:

Custom column:

if List.Contains(Table2[Column1],[Column1]) = true then "Y" else "N"

Result is as below.

@fbostan1 it will be easier if you put a sample data of both tables in excel sheet and the expected output, and share it using one drive/google drive and try to put something together for you.

@fbostan1 well, you have to merge these two tables together on a common key, expand the column you need from the 2nd table, and then write the if condition and remove the unwanted columns.

Hi,

You can merge 2 tables on the basis of at least 1 common column between 2 tables.
