Is there a way to only use one variable as a two-factor interaction variable

[Xamius32]

i dont want to use all class variables for interactions, I want one specific class variable to be used as an interaction variable with every other input variable.

I am talking mostly about enterprise Miner. For example, in the regression node, under the two-factor interactions option.

Is there a simple way to set this up?

Which PROC are you using? Are you using SAS EM?

[Xamius32]

EM, mostly the regression node. Edited to clarify

You need make design matrix on your own, and feed it into regression analysis.
