Relative Record Numbers (RRN)

[Alfredo Delgado <adelgado@xxxxxxxxxxxxxxxxx>]

Good morning.

I work in a JDE environment where most of the tables lack a single 
column I can key queries off of. I find myself having to join multiple 
files and key against multiple fields to get to one buried record buried 
that my user wants to consider changing. My interface is web based and 
if they decide to change the value I'd like to update against the 
relevant RRN instead of dealing with a multi-field where clause of some 
type.

Would anyone like to share real world pros and cons regarding using RRN 
in a similar manner?

Thanks,
Alfred
