===== Discussion =====

An FX Replay Request represents a request to replay, reconstruct, or review selected FX information from preserved records, audit records, provenance records, or evidence-supporting material.

The FX Replay Request identifies request scope, requested purpose, source-record criteria, target information, requesting [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_node|Node]] or participant, authorizing context, timestamp, and [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] expectations.

The FX Replay Request participates primarily in the FX Logical [[dido:99_annexes:annex-b-terms-and-definitions:c:control_plane|Control Plane]] and the FX Logical [[dido:99_annexes:annex-b-terms-and-definitions:a:audit_and_provenance_plane|Audit and Provenance Plane]]. It also relates to the FX Logical [[dido:99_annexes:annex-b-terms-and-definitions:d:data_plane|Data Plane]] when replay produces republished or reconstructed domain information.

===== Note =====

An FX Replay Request does not prescribe a replay [[dido:99_annexes:annex-b-terms-and-definitions:a:api|API]], database query, event-store command, log replay mechanism, test-tool interface, DDS sample, [[dido:99_annexes:annex-b-terms-and-definitions:r:rest|REST]] request, or [[dido:99_annexes:annex-b-terms-and-definitions:r:rpc|RPC]] method.

===== Example =====

An FX Replay Request asks the FX Replay and Reconstruction Node to reconstruct the lineage of an FX Release Package back to the original FX Transaction Candidate.
