DESPERATE PERSON looking for suggestions/best practices for handling drop ships that we don't want i

OK, feel odd asking this after 17 years on JDE World, however, the company I work at now and the Industry we deal with has presented me with some new challenges I have not faced before (always good to keep me thinking).

Currently, any 'ship to' that comes from a customer set up in JDE, even if not a permanent ship to (i.e. a drop ship to an end user), is set up in the Address Book even if we will only ship to them once.  After my heart recovered from this fact, I spent time asking why, etc.

There are a few issues that come into play here - yes, they know how to override the ship to address in the header to 'ship' to a different 'location', but this is when they are doing an 'override' address for a current ship to for certain of our product lines/channels.  This is an issue that is a bit more easily addressed when they get a faxed, phone, or emailed order (although tedious and sometimes non-value added setup).  However, when an EDI order comes in and it cannot resolve against a ship to - i.e. one doesn't exist, etc. -
