Out of the box for detailed payment, you can use a smartlist Purchasing >> Payables Transactions >> All Payments. If the 'All Payments' smartlist favorite is not created, then just add a Search Definition of Document Type = Payment and then also add your date range (20180101 - 20181231) for 2018This will produce a detailed list of all payments, export to excel and create a pivot.
There is also a summary smartlist Vendor Yearly Summary which you would need to add in the 'Amount Paid YTD' from the PM_Vendor_MSTR_SUM table. Now this pulls from the Vendor Summary tables - so for accurate information, you should be doing routine maintenance and running Payables Reconcile (MS GP >> Tools >> Utilities >> Purchasing >> Reconcile) then Summary/Fiscal Year/Calendar Year.
