Product Description and Table of Contents

When designing your global SAP systems, you must consider the key question of whether you should implement one global system or several distributed local systems. This book helps you to make a sound decision and successfully implement the most appropriate system architecture.

In this book, you'll learn about the business process challenges faced by a global enterprise, and you'll explore the technical requirements for carrying out global implementation projects. All relevant subject areas are covered, including the many different requirements global systems must meet, factors influencing the architecture, and available architecture options. In addition, you'll find valuable information and best practices on how to optimally map system topologies through IT. Extensive customer examples and an invaluable decision matrix serve to round off this comprehensive guide.

Highlights

  • Global systems challenges: regional requirements, time zones, data transfer
  • Factors influencing the system architecture: product-related and technical aspects, business processes
  • Various architectures: distributed, regional, and global architecture, combined architectures
  • Technical issues: IT platform, network aspects, tools and central components, special SAP solutions, release management, maintenance
  • Customer scenarios
  • Decision matrix for an optimal system topology
