Evidence attribution refers to the assignment of a period of time to a given piece of evidence during which that piece of evidence will be used for entitlement calculations. The attribution period may range from a basic one to one mapping from the business start and end dates through to a more sophisticated algorithm considering any number of factors. This custom logic calculates the attribution period and the evidence controller takes care of synchronizing these with the specified effective dates – see example(s) below. It should also be noted that the attribution from and to dates can be null in which case the piece of evidence is assumed effective from the case start date to the expected end date.
One of the Evidence Interface functions is calcAttributionDatesForCase and the implementation of this function on an entity class is where the attribution from and to dates are determined for evidence on that entity.
