After customising a report, when trying to run I get error message Please select at least one column. The Report will not then Run or save changes How can I resolve

I can help you in resolving errors and ensuring the successful generation of the report in QuickBooks Online (QBO), @bob.bushby.

Before we move forward, could you please provide the specific report you customised and then ran? This information will help us provide you with the best possible resolution for addressing this concern.

For now, I suggest starting by refreshing your browser. If the issue persists, try opening your browser's private window. This will isolate the cache, which is often the cause of unusual behaviors.

Here are the shortcut keys:

• Mozilla Firefox and Microsoft Edge: Press Ctrl + Shift + N
• Google Chrome: Press Ctrl + Shift + N
• Safari: Press Command + Shift + N

If that works, return to your regular browser and clear its cache. Otherwise, open an alternative browser that's available for you. 

Additionally, you can check these articles for further details on handling and making the best of your reports in QBO:
