Just keep in mind if you ever reorganize the file, the RRN might change
and NOT reflect the actual data order. Another field such as a sequence
number, date, or timestamp, is preferred.

I found my answer in the archives.  

It's the last detail record entered.

As soon as I sent the email max rrn came to mind.

select file.*
from file join (SELECT max(rrn(file)) as maxrrn
                from file
                group by keyfld) rrnf
on rrn(file) = maxrrn

Thanks for your help!
