RMDSWorking Practice 12– To nominate / denominate a Supplier as a recipient of Participant Generator messages was baselined in the Retail Market Design at version 6.0, as detailed within MCR 0123, as part of the suite of changes to satisfy new requirements of SEM implementation.
The Working Practice is to be amended to make it clear that Market Participants can activate their nomination/denomination to relate to dates before and/or after SEM Go-Live.
