When an address is entered from within a case, that address becomes part of the member's person details in the participant manager. It is stored in the list of addresses for the participant. This enables the data to be manipulated with as much flexibility as possible while also keeping the potentially sensitive address information as secure as possible. The application keeps a detailed record of all previous addresses that a participant has used while registered as a participant. The system also maintains a history of previous payments and bills issued to the old addresses.
