It is Same as in Tableau
[PrizeCode]='Prize1' OR [PrizeCode]='Prize2'
The above would return Boolean True/False which you can use
If you need Full Calc:
IF [PrizeCode]='Prize1' OR [PrizeCode]='Prize2' THEN "True" Else "False" End
Your first example worked great.
Thanks for the help.
Thanks for pointing this out to me. I saw post on Linkedin from Tableau that mentioned the same step using Tableau Prep.
The challenge I had using this process was my sample did not show the category type I was trying to filter on.
