MySAP ERP
Encyclopedia
The SAP ERP application is an integrated enterprise resource planning
(ERP) software manufactured by SAP AG
that targets business software requirements of midsize and large organizations in all industries and sectors. It allows for open communication within and between all company functions.
business data system. The first name chosen for the company was not Systeme, Anwendungen und Produkte in der Datenverarbeitung (German
for "Systems, Applications and Products" or the acronym SAP) but originally Systemanalyse und Programmentwicklung (in English, "Systems analysis and programming"). It uses the concept of modules (individual programs that can be purchased, installed, and run separately, but that all extract data from the common database).
SAP AG, the company that provides the enterprise resource planning solution has upgraded the package and launched it as SAP ERP Central Component (ECC) 6.0 in 2005. The purpose of positioning it as ECC is to enable SAP to build and develop an environment of other products that can function upon the foundation of the central component.
SAP's ERP solution includes several modules that support key functional areas, including:
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, other versions of SAP have been released that address these changes. 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 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 services architecture to transition customers to a services-oriented architecture.
SAP HANA which is a combination of inmemory software and hardware can improve data processing at extremely high speeds.
Although there can be major benefits for customers of SAP ERP, the implementation and training costs are expensive. Many companies experience problems when implementing SAP ERP software, such as: failing to specify their operation objectives, absence of a strong commitment or positive approach to change, failing to deal with organizational differences, failing to plan the change to SAP ERP properly, inadequate testing. All these factors can mean the difference between having a successful implementation of SAP ERP or an unsuccessful one.
If SAP ERP is implemented correctly an enterprise can go from its old calculations system to a fully integrated software package. Potential benefits include: efficient business process, inventory reduction, and lead time reduction.

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.

and Secure Socket Layer.

Implementation
SAP ERP consists of several modules including: utilities for marketing and sales, field service, product design and development, production and inventory control, human resources, finance and accounting. SAP ERP collects and combines data from the separate modules to provide the company or organization with enterprise resource planning.Although there can be major benefits for customers of SAP ERP, the implementation and training costs are expensive. Many companies experience problems when implementing SAP ERP software, such as: failing to specify their operation objectives, absence of a strong commitment or positive approach to change, failing to deal with organizational differences, failing to plan the change to SAP ERP properly, inadequate testing. All these factors can mean the difference between having a successful implementation of SAP ERP or an unsuccessful one.

Deployment and maintenance costs
SAP ERP systems effectively implemented can 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.

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.
Communications

ERP advantages and disadvantages
Advantages- Allows easier global integration (barriers of currency exchange rates, language, and culture can be bridged automatically)
- 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
Disadvantages
- Locked into relationship by contract and manageability with vendor - a contract can hold a company to the vendor until it expires and it can be unprofitable to switch vendors if switching costs are too high
- Inflexibility - vendor packages may not fit a company's business model well and customization can be expensive
- Return on InvestmentRate of returnIn finance, rate of return , also known as return on investment , rate of profit or sometimes just return, is the ratio of money gained or lost on an investment relative to the amount of money invested. The amount of money gained or lost may be referred to as interest, profit/loss, gain/loss, or...
may take too long to be profitable - Implementations have a risk of project failure
