6-21. Big Fun Toys (DFDS) Big Fun Toys is a retailer of children's toys. The accounts payable department is located at company headquarters in Charlottetown, PEI. The department consists of two full-time clerks and one supervisor. They are responsible for processing and paying approximately 2,000 cheques each month. The accounts payable process begins with receipt of a purchase order from the purchasing department. The purchase order is held until a receiving report and the vendor's invoice have been forwarded to accounts payable At that time, the purchase order, receiving report, and invoice are matched together by an accounts payable clerk, and payment and journal entry information are input to the computer. Payment dates are designated in the input, and these are based on ven dor payment terms. Company policy is to take advantage of any cash discounts offered. If there are any discrepancies among the purchase order, receiving report, and invoice, they are given to the supervisor for resolution. After resolving the discrepancies, the supervisor returns the documents to the appropriate clerk for processing. Once doc- uments are matched and payment information is input, the documents are stapled together and filed in a temporary file folder by payment date until cheques are issued. When cheques are issued, a copy of the cheque is used as a voucher cover and is affixed to the supporting documentation from the temporary file. The entire voucher is then defaced to avoid duplicate payments. In addition to the cheque and cheque copy other outputs of the computerized accounts payable system are a cheque register, vendor master list, accrual of open invoices, and weekly cash requirements forecast Requirements Draw a context diagram and DFD similar to those in Figures 6-3 and 6-4 for the com pany's accounts payable process, using the symbols in Figure 6-2 6-21.
