Problem summary

• ****************************************************************
  USERS AFFECTED:
  Preserve Type sub-property not available in 7.5.1a.
  ****************************************************************
  PROBLEM DESCRIPTION:
  Currently all group operator aggregation requires the
  incoming data to be either a dfloat or a decimal. If
  the incoming field doesn't match either of these, then
  the field is forced to be one or the other. The customer
  would like to be able to reduce on other field types,
  specifically string, date, and timestamp. Since not all
  of the forms of aggregation apply to these data types,
   the customer only needs a subset of the operations
  (just min and max support). These comparisons should be
  done in the actual type specified.
  
  
  
  ****************************************************************
  RECOMMENDATION:
  patch for APAR JR34374 needs to be applied.
  ****************************************************************
  

Problem conclusion

• Group operator was not originally designed to be able to
  handle anything other than number data types. Special
  Functionality needed to be added in order to accommodate
  the desired functionality.
  
  
  Fix Summary :
  A -preserveType flag has been added to the -reduce and
  -rereduce arguments to the group operator. When this is
  specified, the type of the value specified for the reducer
  input is used. -preserveType is mutually exclusive with
  every form of reduction except for the -min and -max
  arguments. Although the UI will have the added ability of
  being able to specify this flag, additional work will need
  to be done when the customer specifies this flag, since
  the UI still assumes the dfloat and decimal types are all
  that exist as output possibilities. A modify after the operator
