The Campaigns tab of an opportunity record displays any campaigns that are associated with the opportunity, as well as any designations that are associated with the campaign. When selecting a campaign to be tied to the designation, users may also choose a campaign priority and subpriority that indicate how any revenue generated by the opportunity will be used. When querying on and outputting information about a specific opportunity, however, it is not possible to filter by a specific subpriority, or just output the subpriority specified for an opportunity.
