This is actually not a problem but by design. The VFP DBC import is intended to help in the aide of creating your original structures, but in line with the logic of moving to SQL Server, these relationships are not necessary one for one and also require additional information which is something that requires attention by the designer of the database. So unlike importing a SQL Server structure (which does bring in relationships) importing VFP structures only helps get the tables into the database so that the massage and manipulation of the structures can begin.
