Does dBase support SQL queries? If it does, you could write a query that simply grouped the data? I dont have a copy of dBase or similar xBase database, which is why I can't answer the question myself.
Failing that you may be able to create Command Objects pulling the Id and CompanyName in one and then the Id and Contact Name in the other then use the Database Expert to link the two command ojects by the Id?
I also do not have v.9 so I dont know if did not have the Command Object functionality.
