What is SAP ECC?
SAP ECC (also known as SAP ERP) is SAP’s legacy suite of enterprise applications. ECC was designed to run on a third-party database. It started as a Financial software package called RF in 1973, followed by a Material Management module called RM/1. As SAP added additional components, the package was renamed to R/1.
In 1979, R/2 was released, integrating multiple enterprise functions such as accounting, manufacturing processes, supply chain logistics and HR.
R/3 was released in 1992. It was their first client/server package (it no longer required mainframes), and supported a wide variety of operating systems and databases.
In 2004, SAP renamed its core ERP product to SAP ERP Central Component (ECC.) SAP ERP and ECC are now used interchangeably.
