We should use the following steps to create a custom fields.
- Creating a user class - The user class definition is the highest level to extend an application database table.
- Creating user fields - User fields are generic and can be a part of many classes. If the user changes any property of a user field, all user classes inherit the change.
- Associating the user field with a user class - The UET tools look for this association to place the user fields in the form that belongs to the user class.
- Linking an application database table with the user class - The association between a table and a class provides the information that UET needs to retrieve, arrange, and display the user fields that belong to a user class. To link the table with the class, define a rule that determines if the record accessed has a valid user class associated with it. If valid data is entered in existing fields to make the rule expression true, the new user field displays.
- Impacting the schema - Use the UET Impact Schema form to apply the changes you made in the previous steps to all affected databases.
