Microsoft Dynamics NAV has a very consistent user interface, that helps user get used to it pretty fast. Yet it has its own ways, that aren’t so intuitive to most of typical business application users. There is one specific feature which causes a lot of confusion, especially with those users only starting to use NAV. It’s the data persistence: as soon as you enter something in a form, it is automatically saved, you don’t need to press any Save button. Nor is there any Cancel button to forget the changes entered.
