I am thinking about making Control Ship Via Codes = Y and including the Ship Via in my Import Map to ensure the right Service Type is selected.
 
But I am having a hard time trying to figure out how to do that.
 
According to the UPS Help file, the Service Type is 50 Characters, but when you follow it to the "UPS Service Codes" link provided in the same place it gives 2-3 letter codes. I can't see using those codes in Evo, because they are not descriptive enough for customers. For instance, you enter an order and pick ST or TS and no one will have a clue unless they are a UPS shipper (maybe). Even the ones that make sense, like GND for Ground, don't say UPS - could be FedEx or Speedee.
 
If, by some stretch they allow you to use the Description, that doesn't work with Evo because Ship Via is only 15 characters and many of the UPS ones are over that.
 
So if anyone is using this function I'd surely appreciate some guidance.
