T2S Release 3.1 – Scope
Based on the T2S status reporting on 27 August 2019, with the T2S Release 3.1 the resolution of 21 Problem Tickets is envisaged for a delivery in production.
CBF’s final assessment related to these Problem Tickets shows that the fixes do not require software changes in CBF. More details are available in the attached file that provides the latest information about the related PBIs that might have impact on CBF’s customers acting in ICP and / or DCP mode. Customers are recommended to validate these scope elements and check whether operational and / or functional modifications in their procedures are required. Therefore, the file shows from the entire scope elements ten PBIs that will be deployed according to the T2S Service Transition Plan.
The changes to the last published list are highlighted in colour. The comparison shows that:
- PBI 204404 "CDLR status not visible” has been rescheduled for implementation. The resolution is planned to be delivered with T2S Release 3.3 in February 2020. This PBI is related to the T2S GUI and therefore of interest for customers acting in DCP mode.
- Implementation of fixes has been confirmed for:
- PBI 204475 “Missing feedback for "Hold / Release" via "Securities Settlement Conditions Modification Request" (sese.030)”; and
- PBI 204715 “Issue with the restart of RTS procedure”.
T2S Release 3.1 – Transition plan
The Market Infrastructure Board (MIB) will decide on the deployment of T2S Release 3.1 in production once the expected results have been shown during testing. On Tuesday, 10 September 2019, the final decision, known as “Go/No-Go Decision”, is to be made.
The deployment of T2S Release 3.1 into production is foreseen for the business day Monday, 23 September 2019. The implementation of the software will take place during the weekend within the T2S maintenance window. Meaning that currently no changes in the T2S Operational Day are expected; neither for the end of day (“EoD”) procedure on Friday, 20 September 2019, nor for the start of the business day, Monday, 23 September 2019.
The below table provides an overview of the important T2S milestones:
