In the transit time engine where the transit time is specified as from and to
zip-code and country, and maybe also state, it is not possible to specify the
to-part with a range of zip-codes.
In the rate base the to-part is specified as a Drop-off postal code from and a Drop-off postal code to, and as the transit time is related to the rate is very illogical that the transit time engine do not follow the same concept.
Our customer has several carriers shipping to most of the world imagine to number of records to create, not the mention the maintenance work or the impact on response time.
