In SAP ERP, a past R/3 part is called "ECC". SAP is put a force upon the product named APO, BW (BI tool) other than ECC, and SEM, and being changed into the strategy that recommends the customer to combine if necessary and to use them before though was a strategy of R/3 wholly-devoted.
History
The complexity of the software development that kept increasing was feared from the latter half of the 1960's to the 1980's. It is the one that it becomes easy for software to become complex too much, and to cause a fatal mistake. It was the one of making a common business process a capsule by using the approach of the modulation to which one solution to this a lot of people such as Brooks had advocated improved recycling software to its maximum in an internal transaction. As a result, SAP introduced the concept of "Business object" that used object-oriented. It can be thought that "Customer" made "Customer" business object an instance for instance in the system, and however, is interactive ..the definition beforehand.. ..(.. with other objects by a customizable) way. In a sense, SAP is good at the operating system for the business.
SAP R/2 that was the version in front of SAP R/3 succeeded especially from the 1980's to the beginning of the 1990's as a business application software group of the mainframe base. This product especially boasted of popularity with of the multinational company in European nations that needed a software real-time business that handled several languages and a multi currency. When a decentralized client server computing appeared, this company developed the software that was called SAP R/3 to make R/2 correspond to the client server. It corresponds to two or more platforms like Windows and UNIX, etc. , and as a result SAP will acquire a quite new customer base to this in 1999. SAP R/3 is officially announced on July 6, 1992. Afterwards, SAP carried everything before one the large-scale business application market for ten years. ERP6.0 appears as a succession of R/3 and ..user Reich.. GUI becomes possible corresponding to SOA in recent years.
A customizable process is included in the software of SAP, and this can be used so that the enterprise may model my business. Traditionally, these tools do not offer the business process though the tool to construct the business application when software is bought is included. SAP introduces the procedure standardized for this, and this is called the best practice solution in the process. The knowledge of a special consultant who is usually well versed in this best practice is necessary for the use of actual SAP software.
Introduction
Because no one it, and the introduction cost that the parameter and the master should make up the business process, and can use purchase and I as it is become huge, the introduction should not do, and is a package at the level of the business improvement where a very big effect is demonstrated in the achievement of management reforms.
It tends to divide into two types roughly separately, and AS-IS (current state) is divided roughly into the enterprise that becomes TO-BE (type that should be achieved) and the enterprise that can achieve TO-BE that follows the management reform policy by the introduction enterprise. The introduction advantage becomes huge the result of demand of cannot the achievement in the former by the function prepared in the package beforehand increasing and additional development (add-on) cost, and falls at the worst cycle that it is not possible to correspond to the latest social change because the maintenance cost cannot cost much for only the system integration, and the upgrade be done.
Moreover, it divides into two types about the selection of the introduction module, and it divides into the enterprise that introduces only a part of module and the enterprise that introduces all basic modules (financial accounting, management accounting, sales, stock purchase, and production plan/management).
Moreover, it tends to delay cut overs likely more greatly than the first schedule in the Biccban introduction though it cannot be indiscriminately judged that either is good, and only has to judge this by circumstances of an individual enterprise though it divides into a big-bang introduction and a phased introduction about the introduction style.
It can be called a typical product of a top-down introduction of depending on a top lead of the enterprise though it kills though it is made the best use of though ERP 6.0 as the information infrastructure for management reforms has the potential that can be solved to the key task of the enterprise.
