Understanding Address Book Constants
When you set up constants for the JD Edwards Address Book system, you specify these constants in the Address Book Constants program (P0000):
The symbol that identifies which format to use when locating address book numbers.
Whether to enable different mailing addresses for the same address book record based on effective dates.
Whether security is activated for the electronic mail that passes through the system.
Whether to activate personal data security.
Constants are cached information. If you change settings for any of the constants, contact your system administrator to determine what additional steps you must perform for the changes to take effect.
