Create Fields For a Layout

If you'd like to use a field in your layout that isn't defined in your data source (either a business object or a service definition), you can create fields that you can set to variables, or to expressions that reference other fields.

If the existing fields don't meet your needs, you could create calculated fields or virtual fields. You would use a calculated field when you want to use an expression, set a default value, modify labels, and set read-only and required properties. You would use a virtual field if you want a field that has editable sub-fields.

Note:

The fields you create are only used in your layouts; creating a field doesn't create a field in your business object or your Oracle Cloud Application, and doesn't change the service definition. For details on creating fields in your business object, see Create and Edit Business Objects. For details on creating fields in an Oracle Cloud Application, see Define Fields in Configuring Applications Using Application Composer.
