You can link Gift Codes (i.e., products) to a campaign. Having all the associated gift codes in one location can be helpful from a management & donation perspective. These are all shown on the Linked Donation Codes tab of the Campaign Definition and Maintenance screen.

This includes donations and pledges entered into the system or combined with products related to the campaign. If this is a new campaign, then no linked gift codes display. You can use the Code hyperlink to open the Gift Code Maintenance window in a new screen tab. Alternatively, you can click the Fund hyperlink to open the Fund Maintenance screen for the associated fund.
