Thank you for connecting with the Community! Currently, there is no report that could reflect that information. I do have a workaround that can narrow things down. You could use the Vendor Contact list report and sort the vendors in that report by the date they were created or their last modified date That would show the vendors with the newest activity/transactions at the top of the list, as seen in the screenshot below.
However, I see how beneficial this can be. I will go ahead and submit feedback to our Developers about introducing this in future reports. I encourage you to join me in submitting this request!
How do I submit feedback?
If you have any other questions or concerns. Don't hesitate to let me know! See you around.
