When trying to troubleshoot why a consignment didn't allocate to a Delivery Run, it would be great if we could see either;
A) The zones returned from the Transport Zone Set; or
B) A Log, similar to the pricing log, that showed where the process reached and why it failed.
Currently, there are no visible tools to help understand why a consignment didn't allocate to a delivery run, this can be difficult for an end-user to understand.
