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 Journal Template-Batch-Line Pattern

In the Financial systems, Journals are used for accounting. Microsoft Dynamics NAV has an Architectural Pattern called Journal Template-Batch-Line that ensures data integrity, and acts as a datacontract for each transaction.

Technical description

Journals are the datacontracts, employed to create entries that are used for the accounting purposes. They can be used either manually via the user interface, or automated via processes, such as documents or batch programs.

Each Journal has a Journal Line table that has a Journal Template Code, and a Journal Batch Code. The Template can be used to influence the functional user interface, and the reports are being used in the process. The Batch allows different users to use the Journal at the same time without interfering with each other, or temporarily keep data in a Journal until it is ready to be posted.

The following diagram explains how to implement the Journal Template-Batch-Line Pattern...
