By: Marije Brummel

Overview of this book

Microsoft Dynamics NAV is a complete ERP system, which also contains a robust set of development tools to support customization and enhancement. These include an object designer for each of the seven application object types, a business application-oriented programming language with .NET interface capability, a compiler, a debugger, and programming testing language support. Learning Dynamics NAV Patterns will guide you through the NAV way of solving problems. This book will first introduce you to patterns and the software architecture of the NAV and then help you to build an example application. Then, it walks you through the details of architectural patterns, design patterns, and implementation patterns. This book will also talk about anti-patterns and handling legacy code. Finally, it teaches you to build solutions using patterns. Proven patterns and best practices will help you create better solutions that are easy to maintain in larger teams across several locations. It will guide you through combining abstract patterns using easy-to-understand examples and will help you decide which patterns to use in which scenarios.

The following diagram explains how to implement the Compound pattern:

To use the compound table in the application, both the fields are members of the table that uses the attributes. Typically, the compound key values are inherited from the fields in Master Data.


The Compound table is used to define attributes for a combination of two values in the system.


The pattern is used in Microsoft Dynamics NAV for the General and VAT/TAX Posting Setup, which is as follows:
