Validation

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.

There is only one way to abort a user action in Microsoft Dynamics NAV: by using the ERROR function. This function essentially stops the execution of all code, and prevents completion of the user action, whatever such action might be. One of typical situations where ERROR is used to prevent user action is during validation of a new value in a field.
