field <str> has different definitions in relations <str> and
  <str>

  Explanation:  In a CREATE TRANSFER statement of an EXTRACTION
  ROLLUP transfer, you are attempting to move a field which does
  not have the same definition in all the source databases.  Since
  we cannot have two definitions of a field in the target
  database, the CREATE TRANSFER command is invalid.

  User Action:  Re-enter the CREATE TRANSFER statement by
  including only one definition of the field mentioned above or by
  changing all the definitions of this field into the same type.
