How to do a CASE statement in Universe Design

Hello Experts!

I'd like to a CASE statement in Universe Design but I don't know how to do it. Could anybody help me?

I tried this following example but I had no success.

<EXPRESSION>

CASE

WHEN @Select(Product Category\L01 Product Category) = '1000010001' THEN 'BUNGEPRO'

WHEN @Select(Product Category\L01 Product Category) = '1000010001' THEN 'FARELO'

END

</EXPRESSION>

Thank you all!
