Setting the access control to Interface allows you to configure owning groups to control access to parts of an object's data relating the owning group to the Interface containing the data. This prevents other owning groups from accessing the data.
For more information on setting up interface access owning group control, see Interface owning group access control.
If you have previously configured your system to use owning group access control on objects using the ISPFInterfaceDefDataAccessGroup interface, you must set the access property to Interface on every affected form to continue to use that type of access control.
You can search for all the forms that have been configured to use owning groups by running the Forms with Owning Group Control report.
