Hi Adam,

I think they have simplified things a bit. If an invoice is cancelled,
then it has a flag that says it is cancelled. No deletions are
permitted (for audit trails reasons). What happens when an invoice is
cancelled another invoice, which is the reverse of the one that was
cancelled, is created. .

I guess that with this, the solution presented in
http://www.ibobjects.com/TechInfo.html#ti_AuditableSeries, will work.

Anyway, thank you all for the input given.

Fidel.
