Using a simple case when function not working

Hi so I am trying to use an if-then statement in beast mode but it is not giving me the correct output.

The field I am using in this code is product status and these are following values inside it.

What I am trying to do is bucket the values into two buckets one which is repeat and one which is new.

The code that I am trying to use is this

CASE WHEN PRODUCTSTATUS = 'R' OR 'Repeat' THEN 'Repeat' ELSE 'New' END

When I use this define function I only get the value for "new" not "repeat" not sure what I am doing wrong but below is the example

I need R and Repeat to come as repeat and anything else to come up as new if anyone can help me with this code.

    You could try an IN statement instead of OR, something like:

    CASE WHEN TRIM(UPPER((`PRODUCTSTATUS`)) IN ('R','REPEAT') THEN 'Repeat' ELSE 'New' END

    I'm setting it to upper case and trimming whitespaces just to cover the possibility of the data not being clean, which is what I could guess based on the output you currently show in the screenshot.

    It's treating your 'Repeat' clause in your logical expression as TRUE as it's not 0 value. You need to compare the value again to your field:

    CASE WHEN `PRODUCTSTATUS` = 'R' OR `PRODUCTSTATUS` = 'Repeat' THEN 'Repeat' ELSE 'New' END
