I am working on SP 4-2 in Accounting Information Systems by Gelinas, Dull and Wheeler. I know that I am supposed to have 8 flows but I am only getting 7. I have 2 squares Customer and cashier. 2 circles AR Clerk & computer. My Master component is Accounts receivable master file disk. My flows are as follows: I have AR statement going from computer to AR clerk. Customer AR bill going from AR clerk to customer. Customer payment from customer to AR clerk. Customer payment from AR clerk to cashier. Customer payment from AR clerk to computer and unlabeled flows into and out of the Accounts receivable master file. Please offer any tips on what I have missed or inaccurate flows.
