source fields of target relation <str> field number <num> have
  different types

  Explanation:  In a CREATE TRANSFER statement of an EXTRACTION
  ROLLUP transfer, you have entered MOVE RELATION clauses with the
  same target relation name and specified fields with the same
  names but of different data types in the source databases.

  User Action:  Re-enter the CREATE TRANSFER statement by
  specifying fields of the same data type in all the MOVE RELATION
  clauses with the same target relation.
