Error description

• In the parallel enginer Remove Duplicates Stage it is possible
  to
  specify one column for node partitioning and another column for

  This leads to runtime failures  like this:
  APT_ParallelSortMergeOperator(1): Error when checking operator:
  Caught
  unknown exception during wrapDescribeOperator().
  and
  Stagename: Error when checking operator: The view adapter has a
  binding for the non-existent source field "fieldname ".
  Stagename : Error when checking operator: Could not find input
  field "fieldname".
  Error when checking operator: Could not find input field
  "fieldname ".
  main_program: Could not check all operators because of previous
  error(s)
  main_program: Internal Error: (status == APT_StatusOk): sc\sc.C:
  3944
  
  This APAR is to improve the error
