Calculated Attributes are Attributes whose value is derived from manipulating values of other Attributes of the same Dynamic Evidence Type or related Dynamic Evidence Types. These Calculated Attributes are typically used in the Case Evidence View pages in respect of a Dynamic Evidence Type, but they could be used for other purposes as well such as in Validations. For example, a Dynamic Evidence Type for Adoption may have Case Participant Role Ids for the Parent and Child; Calculated Attributes could be defined to calculate the names of Parent and Child from the respective Case Participant Role IDs.
For each Dynamic Evidence Type Version, a Calculated Attributes Rule Set must be defined if the Dynamic Evidence Type Version has Calculated Attributes in its model. The following section describes the process of writing a CER Rule Set for Calculated Attributes.
