Different assertions for different environment?

What I believe is that a test must be having one or more validations on the response. In your case, do want to say, the data will be different in each environment and the previous assertions are not working? May be you need take a look at your assertion carefully and generalize them using regular expressions/patterns etc so that assertions are independent of environments and the same runs every where.

I am kinda new to soapui, I am not sure how to setup the assertions to match environment...

There should not be a problem or wrong for not knowing. That is when one must pay little more attention and learn from different sources. That is just feeling initially, once you know, you say, hey! this is so easy.
