Ashton Fleming has worked furiously for the past month trying to document the major business information flows at S&S. Upon completing his personal interviews with cash receipts clerks, Ashton asks you to develop a comprehensive DFD for the cash receipts system. Ashton’s narrative of the system follows:

Every week, a cash receipts report and an aged trial balance are generated from the data in the accounts receivable ledger. The cash receipts report is sent to Scott and Susan. A copy of the aged trial balance by customer account is sent to the credit and collections department.
Required

a. Develop a context diagram and a level 0 DFD for the cash receipts system at S&S.

b. Prepare a document flowchart to document the cash receipts system at S&S.
