Good morning.  I am evaluating the software for a not too distant purchase.  I need to configure the software to work for two separate departments of "technicians".  One is going to be IT proper and the other will be one of the other service organizations within my company.

I would like my users to hit the web site and click on a new issue submission and be presented with a choice (either IT related or service related).  I believe I have that done as shown below:

When you submit a request it flows into one group or the other as shown below:

The problem I am having now is when I login as a technician I can see tickets for both groups (departments)

I don't necessarily want MIS technicians seeing adjustment requests and vice versa.  I intend to use this method to bring on additional departments in our service related areas when we purchase the software.

Is there a best practice to setting this up?

I created two sites (corporate MIS and corporate Adjustment) and have assigned groups, technicians, etc. from there down.  Did I miss a step or can I get documented hierarchy diagrams somewhere?
