Comment 5 for bug 1172373

So Ben and I have been talking via other channels, and with the help of Mary Llewellyn we've been able to get confirmation that B&T does send electronic invoices that include references to items ordered via Titlesource and items ordered via the ILS.

B&T may not be the only vendor that does this. I'll try to get more data, but this may just be standard practice for vendors using EDI, and as such it would be something that wasn't understood or considered in designing Evergreen Acq EDI functionality.

In case that isn't clear, to illustrate, imagine that in Evergreen you create and activate one or more purchase orders to order items A, B, and C. Meanwhile, you (or somebody else at your site) also goes to the vendor website to directly order X, Y, and Z, without involving the ILS. The vendor may very well send a single electronic invoice back that covers A, B, C, X, Y, and Z.

Evergreen balks at this situation today and fails to process the invoice as a whole. How should Evergreen react to this situation?

With a little bit of new code, Evergreen should be able to ignore X, Y, and Z altogether. There is not enough information in the electronic invoice to construct the line items at this point, so I can't readily see how Evergreen can do otherwise.

But this amounts to ignoring potentially large parts of the electronic invoice, with real dollars involved. Does there need to be a way to inform staff that a given electronic invoice bills for known lineitems A, B, and C but also demands $123 for unknown lineitems X, Y, and Z? If so, we're talking about bigger new development work.

How should this work?
