Programming Microsoft Dynamics NAV - Fifth Edition

By: Marije Brummel, David Studebaker, Christopher D. Studebaker

Overview of this book

Microsoft Dynamics NAV is a full business solution suite, and a complete ERP solution that contains a robust set of development tools to support customization and enhancement. These tools provide greater control over financials and can simplify supply chain, manufacturing, and operations. This book will take you from an introduction to Dynamics NAV and its integrated development tools to being a productive developer in the Dynamics NAV Development Environment. You will find this book very useful if you want to evaluate the product's development capabilities or need to manage Dynamics NAV based projects. It will teach you about the NAV application structure, the C/SIDE development environment, the C/AL language paired with the improved editor, the construction and uses of each object type, and how it all fits together to build universal applications. With this new edition, you will be able to understand how to design and develop using Patterns and new features such as Extensions and Events.
Table of Contents (10 chapters)

Creating an Extension

In NAV 2017 we can publish our changes as Extensions. Using extensions allows us to create customizations without making changes to the source code shipped by Microsoft. This makes future upgrades less challenging for our customers by eliminating the code merge portion of an upgrade.

If you want to create an Extension, you are not allowed to make code changes to most existing objects shipped by Microsoft. There are only two supported object modification categories, those to tables and those to pages.

Table Changes

When creating an Extension, we are allowed to add fields to existing table objects. Adding functions or changing existing code is not allowed.
