Error description

• After ALTER ADD column with a default value, column is added to
  both BASIC table and history table, but DB2 for z/OS does not
  add default value to history table. Doing the same compare again
  with no other changes, DB2 Admin tries to add the default value
  to the history table, but DB2 of z/OS does not allow this and
  fails with:
    -20180 ALTER TABLE PMRTGP41.TESTHISTTBLE ALTER COLUMN EMAIL5
                 SET WITH DEFAULT 'EMAIL 5'
