In delivery_ups module --> ups_request.py --> under def send_shipping() function and def get_shipping_price() function.

I have mentioned ResidentialAddressIndicator as True. Which takes the True/False Value from a boolean field on Customer Master Template (from where we fill customer/company address details along with shipping,incoice and other contacts)

From the UPS Webservices developer guide(https://www.ups.com/upsdeveloperkit?loc=en_CA), the place to push that information is: /RateRequest/Shipment/ShipTo/Address/ResidentialAddressIndicator

and with pdb shell, while debugging, when i print shipment data, I see output given below:

(ShipmentType){
   Shipper =
      (ShipperType){
         Name = "BizPins"
         ShipperNumber = "031V52"
         Address =
            (AddressType){
               AddressLine[] =
                  "2111 Big Timber Rd",
                  "",
               City = "Elgin"
               StateProvinceCode = "IL"
               PostalCode = "60123"
               CountryCode = "US"
            }
      }
   ShipTo =
      (ShipToType){
         Name = "Heather Holm"
         Address =
            (ShipToAddressType){
               AddressLine[] =
                  "101 Commerce St.",
                  "",
               City = "Oshkosh"
               StateProvinceCode = "WI"
               PostalCode = "54901-4864"
               CountryCode = "US"
               ResidentialAddressIndicator = True
            }
      }

but I'm not getting any difference in shipping rates.

The response output from pdb shell is:

RatedShipment[] =
      (RatedShipmentType){
         Service =
            (CodeDescriptionType){
               Code = "03"
               Description = None
            }
         RatedShipmentAlert[] =
            (RatedShipmentInfoType){
               Code = "110971"
               Description = "Your invoice may vary from the displayed reference rates"
            },
            (RatedShipmentInfoType){
               Code = "110920"
               Description = "Ship To Address Classification is changed from Residential to Commercial"
            },

And searching for warning code 110920, I saw that this comes up when user indicated Residential Address is different from AMS Classification. I don't know what "AMS Classification" means?

Any Help or Lead, if possible?

Thanks
