Hi Chuck,

Or just make it a class property.  Some people find that offensive, but it won't cause problems for EOF.  Exposed FK does cause problems.

I'm not one of those people, and I did consider that.  What I've done instead is used the opportunity to look at ERXSequence and NativeDatabaseSequence in particular.  This is one of those perennial "invoice number" situations, where all I really need is an increasing integer sequence.  Integer primary key fit that bill, and I was happy to double up on it, but I'll probably use an additional native database sequence instead.
