Glad to see you here, @LRS RWC.
Since the report that you've pulled up is a transaction-based report that's the reason why you don't see the license number. However, if you want to view the license number of your vendor, you can pull up the Vendor Contact List. Let me show you how.
- Go to the Reports menu, select Vendors and Payable, and then click Vendor Contact List.
- Click Customize Report.
- In the Display tab, check the License number under Columns.
- Click OK.


More details about customizing reports are shared in these articles:
Aside from that, you can also export these reports to Excel so you can combine them and add more customization. Here's a guide for more details: Export Reports As Excel Workbooks In QuickBooks Desktop.
Also, I'd recommend checking out this article: Understand reports. It also includes the complete list of available reports and their descriptions.
