Because multiple profile properties, such as defaultBilling, defaultShipping and secondaryAddresses, can reference the same address item, Commerce Service Center supports cascade-delete data relationships.
For example, you want to move the default billing address to the secondaryAddress, and the defaultBilling property specifies cascade="delete" in the repository definition file. When you change the default billing address item in the customer profile, the current default address item is copied to the secondaryAddress map before being deleted from the defaultBilling property. To disable the automatic copying of addresses, set cascade-delete property to false.
For detailed information on repository data relationship and cascade-delete, refer to the ATG Repository Guide.
