Hi Rebecca
Although there is no standard report that does this, there are many ways to handle it.
I'm going to assume that the $10,000 is annual figure, not an individual payment.
Assuming you are running AP year-end at the proper time, you can do a SmartFinder search for all vendors with "Inv Amt - LY" greater than or equal to $10,000. If you don't know how to use the SmartFinder search as a report writer, this is a perfect excuse to learn - it's one of the best overlooked features in all of Adagio.
Another possibility is to use GridView or Crystal Reports if you have either of those. It's a bit complicated to explain in this reply, but it's not that hard.
Finally, you can preview the Vendor Transaction report for the date range in question, checking off only Checks. Once you have the previewed report on screen, you can export it to Excel, and then delete all but the qualifying vendors. It's a bit tedious, but not too bad.
