Modern businesses of all sectors and sizes, pressured by the high demands of customers and the increasing competition, are gradually moving beyond the model of "islands of automation" and are increasingly advancing towards comprehensive IT support for all their operations.

The initial creation of new specialized systems for this purpose has an extremely high cost; therefore, the solution of using one of the existing "Enterprise Resource Planning (ERP) Systems" packages is usually the optimal solution. This solution offers extensive functionality, many capabilities of IT support for all the company's operations as well as their interconnections, combined with "reasonable" costs.

One of the most widely used ERP systems is SAP. It is characterized by a high level of capabilities and adaptability to the specific needs of each business, but also by high complexity. The book "Comprehensive IT Support for Businesses with SAP" describes in a simple and understandable way, using many screens and diagrams, the basic capabilities that the main subsystems of SAP offer, making it a good introductory text on this subject.

Specifically, it initially provides an introductory overview of Enterprise Resource Planning (ERP) Systems in general, and of the SAP ERP System in particular. Following this is a description of the basic structure of the SAP user interface. Next, the basic capabilities of the main subsystems are analyzed, such as the Financial Accounting (FI) subsystem, the Controlling (CO) subsystem, the Human Capital Management (HCM) subsystem, and the Asset Management (AM) subsystem.

Additionally, the Strategic Enterprise Management (SEM) subsystem is analyzed, which aims to support the higher managerial functions of the business and decision-making processes. Finally, the methodology for the successful implementation of SAP projects in a business is described. The book "Comprehensive IT Support for Businesses with SAP" is aimed at both undergraduate and graduate students, as well as executives and employees of companies with technological or administrative duties, who are interested in an introductory overview of this particularly important yet complex ERP system.
