Address Book Data Security / Data Privacy allows you to restrict users from viewing sensitive Address Book information. After performing the required setup for this feature, secured users will be able to see the secured fields, but these fields are populated with asterisks. These fields are also disabled so no changes can be made.
A recent update in the 9.2 release ensures your Address Book Data Privacy carries over to the Purchase Order Entry application (P4310). See Data Privacy Setting Functionality Available in Purchase Order Entry (Purchase Order Entry) (Doc ID 2565600.1) for the 9.2 Bug / ESU information.
