Most organizations rely on complex enterprise information systems (EISs) to codify their business practices and collect, process, and analyze business data. These EISs are large, heterogeneous, distributed, constantly evolving, dynamic, long-lived, and mission critical. In other words, they are a complicated system of systems. As features are added to an EIS, new technologies and components are selected and integrated. In many ways, these information systems are to an enterprise what a brain is to the higher species--a complex, poorly understood mass upon which the organism relies for its very existence. To optimize business value, these large, complex systems must be modernized--but where does one begin? This book uses an extensive real-world case study (based on the modernization of a thirty year old retail system) to show how modernizing legacy systems can deliver significant business value to any organization.

Master SAP scripts, Smartforms, and data migration with hands-on exercises. The information provided in this book will help you decode the complexities and intricacies of SAP ABAP programming. Pro SAP Scripts, Smartforms, and Data Migration begins by describing the components of a SAP script: forms, styles, and standard texts. It then shows you how an ABAP program can invoke a SAP script form and send data to the form to provide output. You will then apply these concepts to hands-on exercises covering real business scenarios. These scenarios include creating a custom form from scratch to output purchase orders. Smartforms will then be introduced as an enhanced tool to output business documents. The book will show you how to apply the concepts of Smartforms to real-world problems. The data migration material includes details of the Legacy System Migration Workbench (LSMW). This is introduced as a platform from which every data migration task can be performed, minimizing or eliminating programming. What You Will Learn Create and deploy SAP script forms and related objects Modify a copy of a SAP-supplied SAP script form, configure it, and deploy it according to transaction code ME22N Build Smartforms forms and deploy them Carry out data migration using the batch input and call transaction methods Perform data migration using all four methods available in LSMW Modify a copy of a SAP-supplied Smartforms form, configure it, and deploy it according to transaction code NACE Who This Book Is For Readers new to SAP ABAP programming (close to three years of experience or less) are the primary target audience for this book.
