Relationship between tables
I came across an error and am a little confused... When trying to add a relationship, I get the error that says 'There cannot be more than one relational path between any two tables in the graph. Another occurrence of one of the tables must be added to the graph', then asks me for the name I want to assign to this 'other' table. Now, what I don't understand is that I have table A, B, C, and D. I have A-- B, A--C, A--D. BUT, if I try to relate D--B, I get this error. Why is that?
