Abstract
This paper investigates Microsoft’s Enterprise Resource Planning (ERP) System implementation. In particular, it focuses on security and reporting issues relevant to the success of the implementation. The paper includes screen shots of FinWeb and MAP99. It also includes an analysis of the role of data warehouses in ERP implementations. Risks and controls investigated include network exposures, data access, information disclosures, periodic lockouts and warnings and built-in controls.

Title: ABB
Industries: Implementing SAP’s ABC
Daniel E. O’Leary
University of Southern California
Abstract
ABB Industries was told to implement activity based costing (ABC) for costing in their consolidated reports sent to ABB Group, their parent firm. To meet this need they chose to implement ABC, using SAP’s R/3. For two of the nine product lines, parallel ABC was developed. Unfortunately, the version of ABC needed to generate financial statements, operational ABC, would not be available until a later release of the software. While ABB Industries waits for the next release key personnel associated with the implementation are being offered alternative internal and external opportunities. Further, in order for ABB Industries to implement the operational ABC, the entire firm must implement a new version of SAP’s R/3.

Abstract
This paper uses a database, derived from a data repository, in order to do an analysis of enterprise resource planning (ERP) benefits. ERP benefits are important for a number of reasons, including establishing a match between what ERP systems benefits are, as compared to expectations, setting a benchmark for other firms and measuring those benefits. ERP benefits are central to the business case for deciding whether or not a firm should invest in an ERP system. It is found that some benefits vary by industry. In particular, tangible benefits are largely industry dependent, with intangible benefits vary across industry. In addition, when compared to an earlier study by Deloitte Consulting, the results are statistically consistent with their findings, but find additional intangible benefits.

Title: On the
Relationship Between REA and SAP
Daniel E.
O’Leary,
Abstract
The
purpose of this paper is to investigate some of the relationships between the
underlying data models in REA (Resources–Events–Agents a
theoretical accounting enterprise database model) and SAP is the dominant
enterprise resource-planning system. It is found that there are substantial similarities, SAP does have some implementation compromises
that generally keep it from being fully REA. These compromises are based on the
use of accounting artifacts and other, often, implementation-specific
compromises. In addition, there are emerging differences between the two.

Title: When and How Do We Use Heterogeneous Expert Opinion as a Basis for
Research on ERP Systems?
Daniel E. O’Leary
Abstract
Asking experts their opinion is an important methodology in those settings where the major issues have not been previously addressed, often early in the topic’s research
life cycle. Heterogeneous expert opinion (HEO) refers to gathering the opinion of experts that derive from a number of categories, e.g., partner, manager, and senior, or whether
they are accountants or computer scientists. They are heterogeneous in that they are recognized as having different levels and/or types of expertise. Research of enterprise resource
planning (ERP) systems must carefully examine expert opinion and determine when using HEO is appropriate and when it should be stratified. In addition, where possible, previous
research needs to supplement or be compared to the HEO to determine similarities and differences with other groups.

Title: Knowledge
Management Across the
Abstract
Knowledge
management (KM) is used to support enterprise resource planning (ERP) systems
across their entire life cycle. Knowledge management can be used to support ERP
system in their choice, implementation and use, both inputs and outputs. This
paper summarizes a number of actual examples and discusses some emerging
efforts, focusing on knowledge management, with particular interest in
case-based knowledge management. A prototype system designed to support the use
of an ERP system is

Enterprise Resource Planning
(ERP) Systems are powerful software packages that enable businesses to
integrate a variety of disparate functions. In particular, Enterprise
Resource Planning Systems can provide the foundation for a wide range of
e-commerce based processes including web-based ordering and order tracing,
inventory management, and built-to-order goods. This book examines the pros and
cons of ERP systems, explains how they work, and highlights their role at the
heart of e-commerce. This book begins by explaining the background to ERP
systems and goes on to discuss specific systems and their capabilities. He then
focuses on the ERP life cycle, from initial implementation through to the time
when the system goes live. After covering the use of ERP in e-commerce, he
concludes by discussing the risks associated with the adoption of ERP systems.
The book contains several detailed case-studies and will be an invaluable guide
to managers and consultants working with ERP systems.
