aggregate expressions are not allowed in MOVE RELATION clauses

  Explanation:  You entered a MOVE RELATION clause that contained
  an aggregate expression.  The MOVE RELATION clause only allows
  an operator, literal value, or field name.

  User Action:  Check the Replication Option for Rdb Handbook for
  details on the MOVE RELATION clause.  Re-enter the CREATE
  TRANSFER statement with a correct MOVE RELATION clause.
