Probable cause 

You are attempting to KEY JOIN two tables, and there are two or more foreign keys relating the two tables. There may be two foreign keys from the first table to the second table It may be that each table has a foreign key to the other table. You must use a correlation name for the primary key table which is the same as the role name of the desired foreign key relationship.
