Which field type allows grouping related documents such as emails and attachments?

The Group Identifier field is a relational field type specifically designed in Relativity to connect groups of related documents. This is most commonly used to maintain family relationships, such as linking an email to all of its attachments. When documents are processed, a common identifier is populated in this field for all members of a family group, allowing users to easily view and manage them together. This functionality is crucial for maintaining the context and integrity of document sets during review.

A. Fixed length text: This field type stores a specific number of characters and is not designed to create relational links between documents.

C. Whole number: This field stores integer values and lacks the inherent relational properties needed to group document families.

D. Date: This field is used exclusively for storing date and time information and cannot be used to group related documents.
