Thanks for the clarifications, @dendoa.

Allow me to provide additional insights on how to get around this issue. You'll want to ensure you filter the dates to All of your Open Sales Orders by Customer report. This way, it'll show all partially open sales order. I'll show you how.

1. Go to the Reports menu in your QuickBooks Desktop (QBDT).
2. Hover to Sales and select Open Sales Orders by Customer.
3. Then select All from the Dates field. 

If this is not the case, let's perform some troubleshooting steps to isolate and fix this issue. I recommend updating your QBDT to the latest release to ensure the system is running on the newest patch and fixes. Then run the Verify Rebuild tool to fix this. This scans your company file for errors and self resolved them right away. Let me show you how.

To Verify:

1. Go to the Window menu and select Close All.
2. Then, go to the File menu.
3. Select Utilities.
4. Click Verify Data.

To Rebuild:

1. Go to the File menu.
2. Select Utilities.
3. Click Rebuild Data.
