Thanks for the tips!
I will use a timestamp instead.

RRN is notoriously poor performer so if you plan to do this on ongoing
basis, I encourage you to reconsider your solution.

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!
