Comment 2 for bug 1268006

That's a good point, Jennifer. It sounds like we need to make the option for a default a setting (i.e. not automatic) and in cases where the setting is not applied, we need a warning that appears next to the PO Activate link that prevents activation, like the no-item-price and zero-copy warnings. With this, you could still cause the not-found error by manually loading bibs and items for a lineitem (before activation), but you would know why it happened, because the warning would be right at the top of the page.
