Data Types 
User-defined data types can be stored for all programs in the Java Dictionary. The central definition of types that are used more than once in the Java Dictionary allows them to be changed centrally. If a type is changed, all the objects (types or tables) that use this type are established upon generation. The objects that are found are automatically adjusted to include the change.
You can enter semantic information for a type in the type definition in the Java Dictionary. This includes texts that are displayed for the F1 help, texts for use in Web Dynpro, input help, and so on.
The data type definitions in the Java Dictionary are based on the XML schema and have been enhanced with certain properties that are not available in the XML schema. The XML file of a data type created in the Java Dictionary contains, for example, the following entries:
