Learning Dynamics NAV Patterns

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.

We would like to package our application to be easily upgraded to other versions of Microsoft Dynamics NAV. This can either be a new version or a cumulative update. We can also package our software to be implemented in a different localization (country), or even downgrade to an older version of the application.

Creating a Delta file

To ship our software safely between versions, we need to create a Delta file. This defines the difference between our application and the standard application that we started off with when we started programming.

The Delta file allows both the entirely new objects and the changes that we have implemented to the standard Dynamics NAV objects. When the Delta file is applied to another version, we will get a warning if the change cannot be applied because of a conflict or missing reference.

The steps of creating a Delta file

Let's generate the Delta file from our B & B application step by step. To do this,...
