A field is the basic element of data definition in NAV—the atom in the structure of a system. The elemental definition of a field consists of its number, its description (name), its data type, and, of course, any properties required for its particular data type. A field is defined by the values of its properties and the C/AL code contained in its triggers.
The specific properties that can be defined for a field depend on the data type. There are a minimum set of universal properties. We will review these first. Then, we will review the rest of the more frequently used properties, some that are data dependent and some that are not. You can check out the remaining properties by using Developer and IT Pro Help within the Table Designer.
We can access the properties of a field while viewing the table in Design mode by highlighting the field and then clicking on the Properties icon, or by clicking on Properties under View, or by pressing Shift + F4. All of the property screenshots...
