Add Optional Parent

This button adds a new Optional Parent Relationship to a Dynamic Evidence Type Version Model definition, creates a shape in the Model Canvas representing the new Relationship, selects the Relationship, and opens up the Optional Parent Properties Panel.

Dynamic Evidence Type Versions can have multiple Optional Parent Relationships. Create pages for Evidence Types that define Optional Parents will be wizard based. Case Evidence records for all of these Dynamic Evidence Types will be listed in a single list on a single wizard page that is part of the Case Evidence wizard for this Dynamic Evidence Type Version, and case workers will have to select one record from the list as the parent record (i.e. Even though it is 'mandatory' to select one record in the Case Evidence maintenance pages, case workers have an option in which Case Evidence Type they choose as the Evidence Type of the parent record).

It is not valid to have multiple Optional Parent Relationships of the same Evidence Type for the same Dynamic Evidence Type Version, and the Evidence Editor will enforce this restriction.

The following properties can be set in respect of an Optional Parent Relationship:

Table 1. Optional Parent Properties
Property name	Description
Relationship Name	This property sets the Model Relationship Name for the selected Optional Parent Relationship. The value of this property is treated as the internal identifier for the relationship and must be unique across all Relationships in the Dynamic Evidence Type Version.The Relationship Name is never used in the generation of screens for Case Evidence pages, and so the case worker will never see its value. They are however used in the generation of CER Data and Processing Rule Sets for this Dynamic Evidence Type Version - see Eligibility and Entitlement Rule Sets for more details. Relationship Names must follow a specific naming format: They must start with a lowercase English alphabetic character They can only contain lowercase or uppercase English alphabetic characters, numeric characters and underscores They must not contain any reserved words such 'relatedEmployment' or 'comments' as these are reserved identifier in the Dynamic Evidence Editor.
Parent Type Code	This property setting specifies the Evidence Type Code for the Optional Parent. At runtime, the case worker must select one instance of a Case Evidence record for the Parent Type Code during the creation of the child Case Evidence record.
Description	This property configures a non-localizable Model description value for the selected Optional Parent Relationship. This is for annotative purposes only, and is never displayed to the case worker at runtime.
