With QBO Adv., I'm creating a Statement of Financial Activity (non-profit). How do I change the default Section Title from "NET REVENUE" to "CHANGE IN NET ASSETS"?

I can see this is useful in your everyday task, @mhg604. I can share a workaround so you can change the Net Revenue to Net Assets under the Statement of Financial activity in QuickBooks Online.

We export the report as a workaround. Once done, you can modify the file from there. Doing this will allow you to edit all the data in the Excel file. 

Here's how:

1. Go to Business overview and select Reports.
2. Search for and select the report you want to export.
3. At the top of the report file, select the Export icon. Then choose Export to Excel.
4. Save the file somewhere you can easily find, like your Downloads folder.

Moreover, if you're experiencing missing data when opening a report in Excel, it's likely because the file is in protected view. To view the full report, you'll need to select Enable Editing in Excel. 

Alternatively, you can switch between the two views anytime without affecting your accounts or data. It allows you to choose the view that best suits your needs. See this reference: Switch between Business and Accountant view in QuickBooks Online.
