An interface list maps a target system's data exchanges with external systems. You create structured entries using IFID sequencing rules, strict system-name matching, and required metadata like data content, method, frequency, and authentication notes.

The IFID sequencing rule assigns sequential identifiers like IF-NNN for each external system connection. This ensures every API, file transfer, and direct database or MQ connection is uniquely tracked and reviewed within the interface list.

You should generate an interface list after system diagrams are created. It maps data exchanges by linking batch processing IDs and online processing references, ensuring alignment between the system diagram and interface documentation.

Review existing API and file transfer documentation by checking for strict system-name matching, directional send and receive classification, and required metadata. The list standardizes entries in a tabular format to highlight uncertainties or TODOs.

Yes, the interface list supports direct database and MQ connections alongside APIs and file transfers. It classifies these data exchange methods directionally as send or receive, capturing frequency and authentication details for each connection.
