Adding Relationships

Relationships for a Dynamic Evidence Type Version define an association between the Version and other Dynamic Evidence Types. Two such Relationships are currently supported, Mandatory Parents and Optional Parents. It is not possible to create a Relationship between a Dynamic Evidence Type Version and a Non-Dynamic Evidence Type.

Note that such Relationships are always made between a Dynamic Evidence Type Version and a Dynamic Evidence Type - structuring the relationships in this way allows relationships for a Dynamic Evidence Type to evolve over time (e.g. It is possible to add a relationship in subsequent Dynamic Evidence Type Versions).

When creating a Case Evidence record in respect of a Dynamic Evidence Type Version which has one or more Parent relationships, it is necessary to select a parent record before the child record can be created. For example, say we have the following scenario:

We have two Dynamic Evidence Types Income and IncomeAllocation; the Dynamic Evidence Type Version for IncomeAllocation has a Mandatory Parent Relationship with Income; in Evidence terms, IncomeAllocation is a child Evidence Type of Income. When a case worker tries to create a Case Evidence record of type 'IncomeAllocation', they will be presented with a wizard, the first page of which will contain a list of potential Parent records of type 'Income'. The case worker will need to select one of these before being able to create the 'IncomeAllocation' Case Evidence record.

Note: The use of the terms 'Mandatory' and 'Optional' in relation to Dynamic Evidence Type Parent relationships is historical in nature, and slightly misleading. In actual fact BOTH of these Parent relationship types result in the case worker having to select a parent record at run time, so neither are really 'optional'; the optionality refers to their having an option of which parent Dynamic Evidence Types to associate with the Case Evidence record.

Note: A Dynamic Evidence Type Version can have both Mandatory and Optional Parents
