Hi Sadie
You should own GridView - it is the ideal answer for so many questions like this one.
It has two great advantages over the SmartFinder and Filters. 1) You can see the actually payments that make up the total payments, and 2) it can be run for any date range - no matter what the profile settings, no matter what version of Payables and no matter whether you remember to run period end at the right time.
