Good day, @Joyce4Camp.
Thanks for reaching out to the Community for assistance. Let me provide you information about running reports with class details.
QuickBooks Desktop reports offer a variety of customization. What specific report did you run that only allows you to select one class?
As long the classes are selected when you created the transactions, it should be included under the class column. Here’s how:
- Select the Reports menu, then Report Center.
- Enter the Class on the Search field.
- Locate Sales by Item Detail with Classes (example), then run.
- You can click the Customize Report button if necessary.

On the other hand, if you’re referring to a separate column, you’ll want to run the Sales by Class and Item Type report. I’ve attached a screenshot for your visual reference:

You can also generate a Transaction List by Customer report to display the classes you used when creating an event in QuickBooks. Just make sure the Class is marked under Columns in the Customize Report.
Also, here’s an article that will help you with memorizing reports in QBDT. It contains complete instructions to set preferences and how to create and modify them.
Please drop a comment below if you mean something else. I’m always here to guide you. Have a great day ahead.
