The document outlines the functional specifications for a creditor aging report. It takes in input parameters like vendor number, date range, and generates a report with 10 columns showing amounts owed in different aging periods: current, 1-30 days, 31-60 days, 61-90 days, 91-180 days, 181-365 days, 1-2 years, 2-3 years, 3-5 years, and over 5 years. The logic places the amount owed in the appropriate column based on the number of days between the invoice date and current date.
