SAP ERP: Technosap

SAP ERP is enterprise resource planning software developed by the German company SAP SE. SAP ERP incorporates the key business functions of an organization. The latest version (SAP ERP 6.0) was made available in 2006. The most recent Enhancement Package (EHP7) for SAP ERP 6.0 was released in 2013.

Business Processes included in SAP ERP include Operations (Sales & Distribution, Materials Management, Production Planning, Logistics Execution, and Quality Management), Financials (Financial Accounting, Management Accounting, Financial Supply Chain Management) and Human Capital Management (Payroll, e-Recruiting)

Development

SAP ERP was built based on the former SAP R/3 software. SAP R/3 through version 4.6c consisted of various applications on top of SAP Basis, SAP's set of middleware programs and tools. When SAP R/3 Enterprise was launched in 2002, all applications were built on top of the SAP Web Application Server. Extension sets were used to deliver new features and keep the core as stable as possible. The Web Application Server contained all the capabilities of SAP Basis.

As a result of marketing changes and changes in the industry, new versions of SAP have been released. The first edition of mySAP ERP was launched in 2003 and bundled previously separate products, including SAP R/3 Enterprise, SAP Strategic Enterprise Management (SEM) and extension sets. The SAP Web Application Server was wrapped into NetWeaver, which was also introduced in 2003.

A complete architecture change took place with the introduction of mySAP ERP edition in 2004. R/3 Enterprise was replaced with the introduction of ERP Central Component (SAP ECC). The SAP Business Warehouse, SAP Strategic Enterprise Management and Internet Transaction Server were also merged into SAP ECC, allowing users to run them under one instance. Architectural changes were also made to support an enterprise service architecture to transition customers to a services-oriented architecture.

ERP advantages and disadvantages

Advantage

• Updates only need to be done once to be implemented company-wide
• Provides real-time information, reducing the possibility of redundancy errors
• May create a more efficient work environment for employees
• Vendors have past knowledge and expertise on how to best build and implement a system
• User interface is completely customizable allowing end users to dictate the operational structure of the product

Disadvantages

• Inflexibility - vendor packages may not fit a company's business model well and customization can be expensive
• Return on Investment may take too long to be profitable
• Implementations have a risk of project failure
