Most of the IOM-LO gift profiles have the 'Receipt Number' fields available in the field map, except for the eCommerce profile. These fields are important especially to users who have RE configured to make the receipt number a required gift field. This LO receipt number information seems to be available through API calls when testing within the Web Services Console, so it would be awesome to be able to see and map those fields within the LO eCommerce profile as well.
