Attachments (ATT)

Welcome! In this section of the Learning Center you will find resources to support your use of the Attachments (ATT) service. To find the content you need, either use the Search field, view the relevant topics below or browse all learning content from Resources.

An ‘attachment’ is any large mass of unstructured data, for example, the binary representation of a form, imaged data such as a scanned document, or data that is intended to ‘pass through’ the DTCC network without edit from Sender to Receiver (e.g., a private stream of data; either private delimited data or XML document). This attachment data may to be in support of one of the existing DTCC Insurance & Retirement Service messages (XML or Flat File) or may be independent of the suite of messages DTCC currently supports.

Workflow
