The Field Set page is used to add, edit, and delete field sets from the subscriber entity configuration (SEC). A field set is an XML element that contains a group of related XML elements (or fields). Each field set is associated with a specific attribute that makes that field set unique. For example, the pre-defined pool quota field set has an Instance Identifier Attribute called name and contains fields specific to this pool quota. This field set can appear multiple times in the same entity as long as each field set has a unique name value (i.e., the first field set has a name of John, the second field set has a name of Sarah, and the third field set has a name of Harold). A field set also defines each field's properties/validation rules and the order in which the fields are stored.
Note:
A transparent entity field set can be defined but cannot be accessed until it is referenced by a Transparent Entity Base Field Set, or referenced by another Transparent Entity Field Set.
