Instructions provided describe how to enable and re-establish the relationships between geodatabase feature classes and related attachments.

When enabling attachments for a particular geodatabase feature class, a relationship class is automatically created to maintain the link between each feature and its associated attachment stored in the attachments table.

In the event that the relationship class is accidentally deleted, it is not possible to simply build a relationship class between the attachments table and its feature class, while re-enabling the attachment's functionality.

Therefore, the following workflow is needed to re-establish this relationship as well as enable attachments, so that attachments can be added and existing attachments accessed via the Attachment Manager.
