Reverse attachments and how to work with them

The term Reverse Attachment simply means following an attachment back from the Target to the Primary record.

From a Primary record it is a simple matter to navigate to a record that it has linked to. It is also possible to navigate from the Target record back to the record that linked to it.

For example an attachment is made from the Catalog module to the Parties module. The direction of the link is Primary to Target or Catalog to Parties. The link can be followed back from the Parties module to the Catalog module, that is the attachment can be navigated in reverse.
