Compare two fields to populate a new column

[adraus]

I want to do a simple thing...

I want to compare two columns on my report.  If they're the same, I want a new column that says "Yes".

(I'm trying to see if comments were entered by an employee or his supervisor).

This doesn't work:

Column = if([CreatedByUser] = RELATED('Workers(2)'[User]), "Yes")

The error is "The column 'Workers(2)[User]' either doesn't exist or doesn't have a relationship to any table available in the current context."

So what's the deal?  Do the two tables have to be directly linked?  I can't do that...

These snips show the two fields that I'm trying to compare:

I very much appreciate the assistance from users on this forum!  I found that the solution for my situation was that I needed to do more in Power Query, rather than expecting to do column comparisons in the service.

I first did a 'merge queries', bringing the two userid fields into one merged table.  From there, I added a custom column using an IF statement, populating my new column with data from the existing 'comments' column only if the two userIDs were different.  If they were the same, I put "remove" into the new column, instead of the comments.  Then, in a next step, I filtered rows and removed all rows containing the string "remove".

I've got to remember that Power Query is where all the action is.

Many thanks!

@adraus you can use LOOKUPVALUE:

I don't understand how LOOKUPVALUE would help.  I already have both fields on my report.  I just want to compare the two fields and, if they are the same, leave the new column blank.  If they are different, populate the new column.

Measure:

isSame = 

IF(MAX(TableName[User])=MAX(TableName[CreateByUser]),"YES","NO")

[adraus]

I had hopes with the MAX function!  but everything is coming up "NO":

I did a merge of queries to get my two "user" fields into the same table.  In the end, I actually want to put the contents of a field from another table (comments) into my new column, rather than yes/no, based on whether the two users are the same.

If those 2 are measures, try if(measure1=measure2)

Without max function.
