Maintaining Your Data Model › Creating User-Defined Field Types

Creating User-Defined Field Types

CA 2E provides a wide range of default field types that cover many data requirements. If you need a field type that is not defined within the CA 2E product, you can create your own. This topic provides instructions on defining and creating your own field types in addition to the ones supplied by CA 2E's shipped file *Field Attribute Types.

Included in this topic are examples for creating the following user-defined field types.

• Century Date Field Type
• Currency Field Type
• Real Percentage Field Type

Each specific CA 2E user-defined field type has a number of attribute values that will be assigned to any new fields given that type. You can specify which of those values cannot be changed and which can be overridden at the individual field level. You may also specify value mapping and validation routines centrally to the data model for your new field type.

Note: Only a user of type *DSNR may define new field types.
