If you are looking for recent data only, try AP_TransactionPaymentHistory's type "A" records.  This table contains the data shown in the lower grid on Vendor Maintenance's Invoices tab.

Thanks, Kevin!  Would the past 12 months be considered recent data?  That's how far back my client would like to go on the report/export.  

The timeline is determined by the AP Options for retaining Open Invoice data.  (In older versions it is a "days" setting, instead of months).

Got it.  Thank you so much for your input!
