Business Processes included in SAP ERP are Operations (Sales & Distribution, Materials Management, Production Planning, Logistics Execution, and Quality Management), Financials (Financial Accounting, Management Accounting, Financial Supply Chain Management), Human Capital Management (Training, Payroll, e-Recruiting) and Corporate Services (Travel Management, Environment, Health and Safety, and Real-Estate Management).
Overview
SAP ERP is part of the applications in the SAP Business Suite.
Development
SAP ERP was built based on the former SAP R/3 software. SAP R/3, which was officially launched on 6 July 1992, consisted of various applications on top of SAP Basis, SAP's set of middleware programs and tools. 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.
A complete architecture change took place with the introduction of mySAP ERP 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. The SAP Web Application Server was wrapped into SAP NetWeaver, which was introduced in 2003. Architectural changes were also made to support an enterprise service architecture to transition customers to a services-oriented architecture.
The latest version, SAP ERP 6.0, was released in 2006. SAP ERP 6.0 has since then been updated through SAP enhancement packs, the most recent: SAP enhancement package 8 for SAP ERP 6.0 in 2016.
Implementation
SAP ERP consists of several modules, including Financial Accounting (FI), Controlling (CO), Asset Accounting (AA), Sales & Distribution (SD), Material Management (MM), Product Planning (PP), Quality Management (QM), Project System (PS), Plant Maintenance (PM), Human Resources (HR). SAP ERP collects and combines data from the separate modules to provide the company or organization with enterprise resource planning.
Typical implementation phases:
Companies planning to implement or upgrade an SAP ERP system should pay strict attention to system integration to save their SAP ERP implementation from failure. With system integration in place, data flows completely and correctly among various SAP ERP components, thereby not only streamlining business processes but also eliminating or minimizing redundant data entry efforts.

Deployment and maintenance costs
Effectively implemented SAP ERP systems have cost benefits:
Integration is the key in this process. "Generally, a company's level of data integration is highest when the company uses one vendor to supply all of its modules." An out-of-box software package has some level of integration but it depends on the expertise of the company to install the system and how the package allows the users to integrate the different modules.
It is estimated that "for a Fortune 500 company, software, hardware, and consulting costs can easily exceed $100 million (around $50 million to $500 million). Large companies can also spend $50 million to $100 million on upgrades. Full implementation of all modules can take years," which also adds to the end price. Midsized companies (fewer than 1,000 employees) are more likely to spend around $10 million to $20 million at most, and small companies are not likely to have the need for a fully integrated SAP ERP system unless they have the likelihood of becoming midsized and then the same data applies as would a midsized company. Independent studies have shown that deployment and maintenance costs of a SAP solution can greatly vary depending on the organization. For example, some point out that because of the rigid model imposed by SAP tools, a lot of customization code to adapt to the business process may have to be developed and maintained. Some others pointed out that a return on investment could only be obtained when there was both a sufficient number of users and sufficient frequency of use. Deploying SAP itself can also involve a lot of time and resources.
