以全球資訊網為基礎之供應鏈管理資料擷取系統-應用SAP R/3

Abstract

面對產業之競爭，許多公司更新了舊有的資訊系統以面對瞬息萬變的環境挑戰。但是，所導入的企業資源規劃系統往往無法完全滿足供應鏈管理之需求。 因此，本論文提出一個「應用SAP R/3，在供應鏈管理上以全球資訊網為基礎的資料擷取」系統模型，利用網際網路、全球資訊網及相關之程式技術（ABAP/4 、XML），針對SAP R/3用戶於資料擷取列印、資料擷取交換及資料擷取整合之需求建立一個開放式的資料擷取系統模型。 本論文之研究成果在於（1）資料擷取列印：藉由格式與內文分開之方式，解決了SAP專屬列印方式所導致的效能問題及SAP專屬報表設計方式設計不易的問題。（2）資料擷取交換：藉由瀏覽器之普及及XML文件的廣泛被支援，提供了讓文件在供應鏈的上下游中流通的替代選擇。（3）資料擷取整合：藉由一個整合性的Web伺服器之建立，讓各型態之資料庫文件可以匯整至同一區域，能讓使用者無須登入每一台資料庫主機來查詢。提供了企業之全球性資料整合(如全球供應商資料)查詢之替代選擇。 透過此模型系統的運作，可以解決中文報表套表列印時之設計需求。並可為企業內及供應鏈間之數據資料做有效的整合及交換，以建立一個可應用於大部份的企業資訊系統或供應鏈系統中之完整的資訊流通路與具整合性的參考資料庫。

Facing increased competition and shrinking margins, many companies are replacing legacy systems with a new IT architecture designed to maintain a constant flow of information to all facets of its international operations. But, new ERP system is not always optimal for supply chain management. This thesis presents a prototype of logistics flows and information extraction system between customers and vendors by using World Wide Web (WWW), XML with SAP R/3 programming technology (ABAP/4 Language). Three kinds of benefits are approved for most of the supply chain system. They are （1）To resolve the SAP SAPLPD performance issue exists in the Multi-Bytes Character Print with SAPWIN by developing a HTML Layout Set for the report printout.（2）To support business process improvement in customer service, logistics, planning and manufacturing through XML data interface embedded in the software solutions.（3）To provide a reliable and scalable information technology infrastructure which could fulfill data transparency and data consistency requirements. As prototyping is set up. Through this running prototype, we demonstrate an open architecture of data extraction method. It can be used in data transparency and data consistency for a supply chain. Enterprise within multi database can improve information flows performance. It can solve data printing problem within many types of layout set for enterprise requirement.
