Table join on non-primary key

Content

Hello,

I'm faced with a situation where I need my a report to map a custom field (string) in the incident table to one of 4 categories.  There are ~1000 possible strings that need to be mapped.

I created a custom object that maps the possible strings to the categories.  While trying to report on this, I don't see a way to join the two tables by the matching string fields, only by primary key.  Is there a way around this or am I just not trying to solve my problem correctly?

Thanks,

Barry
