SAP has several layers. The Basis System is the heart of the data
operations and should be not evident to higher level or managerial users. Other
customizing and implementation tools exist also. The heart of the system from a
manager's viewpoint are the application modules. These modules may not all be
implemented in a typical company but they are all related and are listed
FI Financial Accounting--designed for automated management and
external reporting of general ledger, accounts receivable, accounts payable and
other sub-ledger accounts with a user defined chart of accounts. As entries are
made relating to sales production and payments journal entries are
automatically posted. This connection means that the "books" are designed to
reflect the real situation.
CO Controlling--represents the company's flow of cost and
revenue. It is a management instrument for organizational decisions. It too is
automatically updated as events occur.
AM Asset Management--designed to manage and supervise
individual aspects of fixed assets including purchase and sale of assets,
depreciation and investment management.

and monitoring of long-term, highly complex projects with defined goals.

cross-application technologies, tools and services

additional industry-specific functionality. Special techniques have been
developed for industries such as banking, oil and gas, pharmaceuticals,
