Ok. I found that they have in common that the INVNUMBER contains a
date field (all different, but an example: Wed Dec 28 15:59:01
201131932). None of the items are marked as 'invoice' (invoice column
value 'f').
None of the AR records are being referenced in ACC_TRANS. Could this
be a case of a transaction being prematurely committed and then
cancelled?

Hmm. Maybe these are records from SL's create-unique-and-then-update
strategy. Maybe it's impossible to install a NOT NULL constraint on
the records at this time. That's a pity; I thought I'd be able to find
out what causes it by installing one and waiting for people to run
into trouble :-)

Bye,

Erik.
