This does not work:In the Choose a vendor drop-down, select the desired vendor. If an item has a Preferred Vendor, this is automatically filled on the Purchase Order.

Thanks for getting back here, TBell2.

I've tried this on my test company and can confirm that the vendor and item will automatically fill on the Purchase Order after clicking the Reorder option.

To check for any potential cache issue impacting the purchase order, let's do some basic troubleshooting steps. We can start by opening an incognito or private browser. This mode will not save your browsing history.

You can use these keyboard shortcuts:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Safari: Command + Option + P

Next, sign in to your QuickBooks Online account and follow the steps shared by my colleague Mark_R. If it works, go back to your regular browser and clear its cache. Finally, restart your browser to refresh the settings.

In addition, you can try using a different supported browser.
