[otrs] Department Field in Customer Table

Hello - I almost have my OTRS customized to exactly the way I want it, with one exception. I would like to have a field in my add-customer screen that asks for a "department". I tried using customer groups for this but its not really what I am looking for. I wish to be able to do a SQL query that produces a report of total tickets/time per department in my organization. Has anyone done this successfully? -- Glenn Campbell
