Hello there, Dennis Home. 

I'm joining this thread to help you get a report without showing the Not Specified. 

The report will generate data depending on how the class is being tracked. The same goes for location.

When we apply class for the entire transaction, we'll have to use the transaction with class reports like Transaction Detail by Account Report group by Class. Here's a sample screenshot on how we track the class/location for the entire transaction.

On the other hand, if you have assigned class per item, we'll need to generate a detailed report. Otherwise, we'll get the Not Specified since your transactions will split based on the class assigned per item. Here's a sample screenshot on how we track class per item:

Also, it's important to use the correct assigning classes to reflect the data according to your needs. To do it, we can go to the settings. Here's how:

1. Go to the Gear icon.
2. In the Advanced tab, choose Categories.
3. Then, select either One to entire transactions or One to each row in transaction.
4. Click Save. Then, Done.
   

Once done, review your existing transactions to reflect the class accurately. You can do it from the report you pulled up. Here's how:

1. For example, you have the Sales by Class Detail Report. 
2. Go to the Not Specified section. 
3. Then, click the transaction or amount. 
4. Double-check the transaction. Make sure to assign them to the appropriate class.
5. Click Save to reflect the changes.

I've gathered a few articles for additional tips and details about reports and class:

• Learn how to get the most out of your financial reports.
• Use classes to track income, expenses, or profitability by business segment.

Please let me know if you have further concerns about the QuickBooks report and assigning classes in the program. Take care and have a good one.
