When adding a soft credit recipient to a gift record, a user may wish to edit the gift type so it can appear different on the soft credit recipient record. For example, the main or "hard credit" is a Pay-Cash, but the user wishes to see a Cash type on the soft credit recipient's record.
A soft credit on a constituent is a link to the "hard credit" gift record from the actual donor. That means its values, such as gift type, come from that main "hard credit" gift record. The only fields are unique to the soft credit that can be edited are the soft credit recipient and the soft credit amount.
