Many to Many Modeling

How is the group handling Many to Many relationships when modeling relational data. Are you combining the two tables into a single query subject? What are you doing with the Junction table? We have a number of many to many relationships in our transactional system, and I would like to figure out a semi standard way of handling them.
 
I think the standard procedure is to create 1 model subject query out of 2 facttables. The obvious example is order header vs order detail. Both can be considered facttables and should be remodelled into 1 model query subject.

How do you compensate for overcounting etc with many to many relationships?

Not sure yet because I haven't come to the point where I've run into the problem.

The Web Seminars on Cognos Support have been very helpful. I'm enjoying them.
