The Missing Class report the product and service items not assigned to a class.
Important: You must assign all products and services to a class in Millennium so you can identify products and services in QuickBooks. If you do not assign a product or service to a class, they will display in QuickBooks as an "unknown item".
Tip: Run the Missing Class report before uploading Millennium data to QuickBooks for the first time. You can then correct any unassigned items in Millennium using the report findings so that each item uploads correctly to QuickBooks.

Open your company file in QuickBooks.
Open AccountSync.
Select the location for which to run the report.

Select Reports > Missing Class Report.
The AccountSync Report window displays with details of the items not assigned to a class.
