For security reasons, reports created in the Blackbaud Hosting environment cannot connect directly to the database using an ODBC connection. However, connecting to exported data in the Blackbaud Report Writer Database (MDB) format is fully supported.
If you are hosted and you need a report to access the back end tables of your database, please email email@example.com to inquire about our Custom Report Writing Services.
Please review the following Knowledgebase Solution if you're self-hosted (not hosted by Blackbaud):
