To run a report that includes multiple Relationship Types, the standard Relationship Export can be used.
  1. Click Management in the menu
  2. Click Standard Exports
  3. Click the Relationship Export on the left hand side under Account Exports
  4. Select your query at the top of the page. If you'd like to report on all relationships in your database, set the query to Base>All Constituents
  5. Select All Relationships in the drop down menu in the Relationships section
  6. Select a Report Format
  7. Click Submit
As this is a standard export, the format of the report cannot be modified. No additional fields can be added to it, nor can fields be removed.
