"[SOLVED] Generate Attribute - Duplicate"

Hi,

I was wondering if it's possible to look at a particular attribute and determine duplicates in the Generate Attributes operator.
i.e. If Att1 has duplicates then Att2 = x

Thanks.

Cheers,

    Hi,

    It is not possible in the "Generate Attributes" operator directly, but with a few preceding operators. See the process below.
