Final answer:
In a logical DFD for a B/AR/CR process, a credit memo would be sent by the manage customer accounts process to the customer. This process handles the accounts receivable management, including the issuance of credit memos for overpayments, returns, or other transactions.
Step-by-step explanation:
In a logical Data Flow Diagram (DFD) for a Billing/Accounts Receivable/Cash Receipts (B/AR/CR) process, manage customer accounts is the process you would expect to send a credit memo to the customer. The perform billing process is typically responsible for creating bills and invoices for services or products delivered, not for handling credit memos. The receive payment process is where payments are processed and applied to customer accounts. Finally, the validate sales order process is concerned with ensuring that the sales orders are accurate and properly authorized before billing can occur.
The issuance of a credit memo is part of the accounts receivable management, which falls under the scope of managing customer accounts. A credit memo is issued when there has been an overpayment, a return of goods, or any other transaction that requires the customer's account to be credited. Therefore, the B/AR/CR process that involves sending credit memos to customers would be part of the manage customer accounts aspect of the accounts receivable function.
