I would recommend this book to Finance users who are currently working on NAV. During project implentation, NAV Consultant may have skipped some functionalities which are not required at that time. This book will tell you the leftover. This book can also be used as a reference as and when needed.
This book is also useful for NAV consultant who are not specialized in Financial Management. Technical Consultant and Functional Consultant who specialized in modules other than Financial Management can use this book to get an overview what's in NAV Financial Management. It's always useful for all NAV Consultants to know Financial Management because it is the core module of ERP.
This book is also useful for NAV Finance Consultant who just get started on NAV. Experienced NAV Finance Consultant won't get much from this book.
