CDS – ILE Dual Running Service Design Document

The baselined version of the  CDS ILE Dual Running Service Design Document has been updated with your queries and feedback.

Key Updates:-

  • Corrected SOE values mapping between CHIEF and CDS
  • SOE mapping section simplified with new priority tables and separate CDS values table
  • Although it is CDS-ILE only functionality, for completeness we have included RET(Retrospective Arrival) and QUE (Query Requests) process flows
  • The change in delivery approach is reflected in the document
    • There will now only be a single release for CDS-ILE Dual running from HMRC rather than a two Phase Release as planned earlier
    • This does not affect the way CSP/Software Developers were planned for ILE dual running migration and dual running
    • Phase 1 is now referred to as CSP migration Phase and Phase 2 is referred to as CDS-ILE Dual Running Phase

The document will also be available on Google Drive in the following folder: CDS 01 Inventory Linking Exports.
