This transaction set facilitates the electronic transmission of files between trading partners in an EDI environment. The File Transfer (996) is typically sent by a sender to a receiver to deliver file content or confirm file exchange capabilities. Key segments include the BGF (Beginning Segment for File Transfer Information), which establishes the file transfer context and parameters; the K3 (File Information) segment, which can repeat multiple times to convey detailed file characteristics, contents, or transmission details; and the ST (Transaction Set Header), which identifies this as a 996 transaction and provides control information for proper message routing and sequencing.

For example, a logistics company like ShipCo might send an X12 996 transaction set to its warehouse partner, WarehousePro, to transfer updated inventory master data files or to confirm successful receipt of a previously transmitted manifest file. The BGF segment would specify the file type and transmission method, while multiple K3 segments would detail file specifications such as record counts, file size, creation date, and any compression or encryption applied. This structured approach ensures both parties maintain synchronized records and can verify that file transfers completed successfully without corruption or loss.
