Does anyone know at what point amounts get added to the Period to Date Purchases field located on the Summary tab in A/P Vendor Inquiry? Is it when a PO was written, receipts against a PO were entered, a check was written to that vendor, or something else? Also, what date is being used to determine which PTD bucket the amount is added to, the PO/Receipt/Check Date or the Transaction Date? I know this is probably a pretty basic question, but I can't seem to reconcile any possible answers with our data.
