You can modify the properties of an existing entity within a model.

To modify an entity

1. In the Models list, select the model that you want to edit and then click Edit model button. The model editor appears.
   
2. In the model editor that appears, in the Entities list on the left, select the entity that you want to modify. The properties appear in the workspace and the Attributes and Relations lists populate with any associated attributes and relations.
3. In the workspace, change properties as necessary. The table below details the properties.

   Entity Properties

   Property Name	Type	Description
   (Id)	ID	A unique identifier for the entity. Used internally by the system.
   Name	String	The name of the entity.
   Binding	ID	The database object that the entity represents.
   CollectionName	String	The name to be used for a collection of instances of the entity. Use this property to ensure that plural nouns are spelled correctly.
   Description	String	A description of the entity that appears as tooltip text in the Report Portal when a user hovers the pointer over the entity.
   Hidden	Boolean	Indicates whether the entity is hidden from end users.
   CollapseInRelations	Boolean	Indicates whether to collapse the entity when it is displayed within a relation.
   Security Filter	Expression	Allows you to use custom security providers to filter the data displayed for the entity. See Managing Single Sign-On Security Providers for more information.
   DefaultAggregateAttributes	Object	Determines the attributes to display by default when the entity appears in an aggregate.
   DefaultDetailAttributes	Object	Determines the attributes to display by default. For example, when you drag the entity onto the designer surface and create a table or chart, these attributes display by default.
   IdentifyingAttributes	Object	The set of attributes to use to identify a unique instance of the entity. This is used instead of DefaultDetailAttributes to build a table or chart if that collection is empty, since this one is never empty. This is also used to create the grouping label when you group an entity.
