What reda.045 is for

An instructing party sends a SecurityCSDLinkCreationRequest message to an executing/servicing party to request the creation of the link between a financial instrument and a CSD in their system.

The instructing party - executing/servicing party relationship may be:

- Central Securities Depositories (CSD) who would like to publish security CSD Link static data, or

- a Corporate, or

- a Bank, or

- a Market Infrastructure, or

- a Market Data Provider.

The request is sent when the instructing party identified a gap in the security CSD Link coverage of the executing/servicing party. The instructing party needs this security CSD Link to be set-up at the executing /servicing party to perform its activities.

Initiator: instructing party.
