• The properties of many fields can change at one time by changing the properties on the EDT.

Extended Data Types

• Some important facts about Extended Data Types are in the following list:

Extended Data Types

• Extended Data Types can be based on primitive MorphX data types or on another EDT.

• If it is possible, custom tables have fields based on Extended Data Types.

• A relation can be assigned to an Extended Data Type and it can be made a Related Field Fixed relation.

Extended Data Types

• Most fields in Microsoft Dynamics AX 2009 tables are based on Extended Data Types. After it is created it can be reused as many times as it is needed in the application.

Base Enumerations (Base Enums)

• Base enumerations are used as data lists for fields of the Enum type. Base enumerations, also named Base Enums, are used for assignment to Enum primitive data type fields that require a set of predefined values.

Views

• A Microsoft Dynamics AX 2009 view is a virtual table that provides the data records and fields that are specified by a query. The following sections describe views and how they retrieve data.
