a FOREIGN  KEY  referencing  field  does  not  correspond  to  a
  referenced field

  Explanation:   The  referencing  fields  of  the   FOREIGN   KEY
  REFERENCES  relation-specific  constraint  being  defined do not
  correspond to the referenced fields of the  referenced  relation
  in either number or type (datatype, length, and scale).

  User Action:  Choose referencing  fields  for  the  FOREIGN  KEY
  which  correspond  to  the  referenced  fields  of the UNIQUE or
  PRIMARY KEY of the referenced relation.
