What Purchase Reports should provide
Purchase Reports should turn governed requests, supplier quotations, purchase orders, receipts, inspections, returns, invoices and payments into repeatable evidence for demand, order, supplier, receipt, quality, spend and payable visibility. Every result needs a defined business question, calculation or report rule, unit, period, filter, source and accountable reviewer.
Review percentages with absolute values and exceptions. A result that cannot be traced to its source record should remain provisional until the data and definition are reconciled.
