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

  Explanation:  In a DEFINE 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 DEFINE TRANSFER command is invalid.

  User Action:  Reenter the DEFINE 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.
