SIA COMPANY has decided to document and analyze Hexagon's accounts payable process to facilitate the transition to computerized systems. He also wants to improve the vulnerabilities found in the system. In the next story, SIA explains what's happening in Hexagon. Before Hexagon pays the vendor's invoice, the invoice must be matched against the purchase order used to request the goods and the receipt report produced by the receiving department. All three documents are entered into accounts payable at different times, so a separate numerical file is maintained for each document type. The purchase orders that are forwarded from purchasing are stored in a purchase order file. The receiving reports are stored in a receiving report file. Upon receiving the vendor invoice, the accounts payable clerk records the accrued amount in the account payable file and files the invoice in the vendor invoice file. Hexagon will pay all invoices within 10 days to take advantage of the discount. Upon payment of the invoice, the accounts payable clerk retrieves the vendor invoice, attaches the purchase order and receives the report, and transfers the adjusted document to SIA COMPANY. SIA checks the documents to make sure they are complete, prepares a two-part check, transfers all the documents to Laura, and records the check in the cash disbursements journal. Laura reviews the documents, confirms that they are valid payables, and signs the check. She forwards the check to the vendor and returns the documents and the check copy to the accounts payable clerk. The clerk saves the documents in numerical order in the paid invoice file. At the end of every month, the accounts payable clerk uses the accounts ledger to create an accounts payable report, which is forwarded to Laura. After she finishes the report, Laura files it in chronological order. REQUIRED! Based on the above narration, prepare a document flowchart to document accounts payable processing at Hexagon
