CHAPTER ONE
INTRODUCTION
The Revenue cycle and access management system (RCAMS) is an operational system that supplies the reports and data that are used for the audit of the Custodial Revenue Statements of the IRS by the General Accounting Office (GAO). A major objective of the custodial Revenue reporting system is to be continuously and accurately responsive to regular and ad hoc requests for custodial revenue reports.
Access control is the ability to permit or deny the use of a particular resource by a particular entity. Access control mechanisms can be used in managing physical resources (such as a movie theater, to which only ticket holders should be admitted), logical resources (a bank account, with a limited number of people authorized to make a withdrawal), or digital resources (for example, a private text document on a computer, which only certain users should be able to read).
Revenue and Refunds
This system is used to identify all of the detailed transactions that posted to the Individual Master Files (IMF), Business Master Files (BMF), Individual Retirement Accounts File (IRAF), and Non-Master Files (NMF) during the fiscal year. These detail transactions are broken down into Revenue transactions, Refund transactions, Other Transactions that are part of the fiscal year, and Other Transactions that are not part of the fiscal year. Once these breakouts are done, revenue and refund reversal transactions are matched to the transactions they reverse. Paper and electronic reports are generated and distributed to the Office of the CFO and to GAO. The detailed files provide support for the amounts from the Interim Revenue Accounting Controls System (IRACS). The files are also made available to GAO for sampling and to validate the revenue statements.
