Re: [ EXTERNAL ] Re: Does an Relative Record number ever change

[Ken Meade <kmeade@xxxxxxxxxxxxxxxxx>]

This discussion brought up a lively debate during a meeting on how often "it" happens, it being a reorg or records in a specific table getting deleted and reused.

To me, if it happens once... that's one time to many to use something like RRN as the key.

There was a day when things like MAPICS used RRN to connect items in a 
bill of materials. A reorganization could mess that up, IIRC, and 
probably reusing deleted records, too.

Gone be the good old days, eh?
