use the saw function in results column to display a value of the comparison rows

I have a combined analysis report that shows the max of 2 records for each company.

Both rows will show a date field and a created by field

I want to compare the two date fields for that company to get the max date and then show the created by person in both records.  I have the function to get the max date showing properly.

Example

Company Name          Comparison Date          Created by     Column to show the max date: max(saw_1 by saw_0))            Column to show the Created by person of the max date??

Company ABC               1/1/2015                       User123                               3/1/2016                                                                                                     ??

Company ABC                3/1/2016                       User999                               3/1/2016                                                                                                    ??

Not sure what saw function to use (if possible) to show User999 on both rows.
