I'm trying to create a report in NPSP of all gifts made to a specific campaign that shows both households and organizations. Can someone please tell me which report type I should use?

@Sherry Ladislas How do you determine whether a gift belongs to a campaign? Do you use the primary campaign source field on the opportunity? Or do you use a separate object (like GAU Allocations)?

That will determine what report type will work the best for you. If you use Primary Campaign Source, I would just use the report type Opportunities and filter by the campaign source. If both household and organization gifts are created as opportunities, that should show them all.
