What is Mini SAP? MINISAP is a full-fledged Basis SAP system without the SAP applications (FI, CO, MM, SD, etc.). It has every Basis function of a standard SAP-R/3 system (ABAP/4 Development Workbench, Data Transfer Workbench, Computer Center Management System - CCMS, etc.) and, therefore, is a very good means to get exposed and trained in ABAP/4 programming language.
