Unless you tell forms to apply each record to the DB as it is entered using either post or commit it won't work.
Those records are only in the form until one of those commands is issued. So a query against the DB will give the same result each time.
But I suggest you use an actual DB sequence instead, that's what they're there for, and if you don't sooner or later two users will generate the same item code at the same time.
