Description

Introduction

BAAN’s 4GL (Fourth Generation Language) is the core programming language used within the BAAN ERP environment to develop, customize, and extend system functionality. It enables developers to design sessions, reports, menus, and scripts that support complex business processes. This course provides a foundational understanding of BAAN 4GL syntax, structure, and practical programming techniques for ERP application development. Participants will learn how to create programs, manage data, and interact with the BAAN database effectively.

Prerequisites

• Basic understanding of ERP systems and BAAN IVc4 architecture

• Familiarity with relational database concepts (tables, queries, joins)

• Prior programming experience in any high-level language (optional but beneficial)

• Knowledge of business process modules in BAAN (Finance, Logistics, Manufacturing)
