Entities
Through the form modeler, the business entities are modeled. It is also possible to model relations among entities to represent their interaction. The relations defined in this panel can be modeled in the referenced entity so that they are reflected when using the corresponding form.
An asterisk "*" on the label indicates that the property is required.
To define a relation with an entity, first select the entity to establish a relation with, and then complete a set of properties.

Example of Filtered Entities
This example describes how to model a form that includes a field related to an entity, applying a filter based on the value of another field in that form.
1.Entity modeling
A "Product Catalog" entity is modeled with the following fields.
ŸCode: Unique product identifier.
ŸDescription: Product detail or name.
ŸCategory: Product classification (e.g. vehicles, real estate, household appliances).
2. Page modeling
On the "Purchase Request" page, the following fields are included.
ŸProduct Category: related to a value list.
ŸProduct: related to the "Product Catalog" entity.
3. Filter configuration on the Product field
ŸModeling the relation with the "Product Catalog" entity.
ŸAdd a filter in order to define that the "Category" field of the "Product Catalog" entity matches the value selected in the "Product Category" field of the form.
When executing the form, if a category is selected, in the "Product" field will only display catalog values corresponding to that category.
