Draw a flow chart based on the following narrative,

The mail room of the Jackson Ltd receives invoices from various suppliers. The invoices are sorted in the mail room and then passed on to the accounts payable officer. The details of these invoices are entered into the computer by the accounts payable officer. The computer compares the details of the invoice entered against the details kept in two different computer files. The first is the purchase order int the 'purchase order' data file; and the second is the receiving report in the 'receiving report' data file. The accounts payable officer clicks on 'Approve' button to confirm that the 3-way matching process has completed successfully. The computer saves the details to the 'Approved payment' file. Three copies of a payment voucher are then printed by the same computer process. One copy is sent to the cashier. The cashier signs the voucher and files it according to the payment due date of each voucher pending payment. The copy is sent to the department which initiates the purchase. The copy is then checked and filed according to vendor name.
