In October 2004 Microsoft announced Navision 4.00 as what we expected to be the last "old" Navision.
This version is the first with the MenuSuite object, which Microsoft describes as a "new user interface, modeled after Microsoft Office Outlook 2003". It also introduces the XMLPort as an alternative to the dataport.
Business Notifications were another new feature in this version. It was build on Microsoft SQL Server Notification Services, a platform designed to ease the pain of developing and deploying notification applications that generate personalized, timely information to subscribers. I was introduced in SQL 2000, but discontinued and removed from SQL 2008. It never really became the expected success, but stayed in NAV until version 2009.
A new Intercompany Postings Module was also added in this version. The functionality focuses on supporting inter-company transactions with sales and purchasing documents, and with General Journal lines.
Microsoft also introduced a new security model for SQL. All databases now uses a so-called Enhanced Security Model. This used a way to actually assign permissions directly in SQL, but it required a synchronization of the permissions each time they were changed in NAV. A timely process where users could not work with the system.
In Dynamics NAV 4.0 SP2 (update 2)/SP3 you no longer need to use the new security model that was introduced with 4.0. You can now choose between a Standard security model (Before 4.0), or the Enhanced model (4.0+) which requires synchronization. But the Enhanced model remains the default until NAV 2016, despite almost noone uses it.
A new Navision Employee Portal was introduced in this version. Integrated with SharePoint and Windows Server 2003, this was another technology that didn't stay for more than a few releases. Item costing was another improved area.
Originally released in April 2006, but the quality of the releases was not good. In August update 2 was to be releases, but is pulled again as new problems are found.
The quality of the releases continue to disappoint. It takes Microsoft until service pack 3 update 6 to get it almost right.
Only the latest builds of 4.00 SP3 (update 6) were able to run on Windows Vista, or any later Windows versions.
Microsoft's support of Dynamics NAV 4.0x stopped on October 7th, 2011.
