Field Descriptor Table (FDT) Record

The Field Descriptor Table is a reserved or special ACID that contains and manipulates fields. These fields give you the ability to define variable length data to the Security File, and can be predefined by CA or defined by the user. Before attaching a field to an ACID, it must first be defined to the FDT. Predefined fields can be modified immediately since they already exist. A sample of some of the predefined fields you can find in the FDT appear below.
