SAP FI/CO OVERVIEW

SAP, started in 1972 by five former IBM employees in Mannheim, Germany, states that it is the world's largest Inter-Enterprise software company and the world's fourth-largest independent software supplier, overall.

The Original name of SAP was "SYSTEMS APPLICATIONS AND PRODUCTS"

SAP applications built around their latest R/3 system, provide the capability to manage financial, asset, and cost accounting, production operations and materials, personnel, plants, and archived documents. The R/3 system runs on a number of platforms including Windows 2000 and uses the client/server model. The latest version of R/3 includes a comprehensive Internet-enabled package.

At the early stage it was used on R/1. Later on it was developed to R/2. And now the most advanced version is using R/3.
