Hello, @ddaileycpa. I'll ensure you can view the Assembly report in QuickBooks Desktop (QBDT). 

We can generate a custom report displaying the items used in Build Assemblies.

Here's how:

1. Go to the Reports menu and select Custom Reports.
   
2. Choose Summary.
   
3. From the Display tab, set the date range to the period you need.
4. On the Display rows by drop-down, select Item detail.
5. Under Display columns for, select Quantity (select Amount if the dollar amount is required).
   
6. On the Filters tab, remove the Account filter.
   • Add Transaction Type then select Build Assembly filter.
     
   • Add Detail Level then select All except summary filter.
     
7. Click the OK button.

Refer to this article for more information about running and customizing your reports: Customize reports in QuickBooks Desktop.

Once you're done, you can memorize this report if you want the same settings to be available for future use: Create, access and modify memorized reports.
