As part of 2015 Remedy (McCloud), member data on Compendia is being ‘rolled back’ by the Scheme Administrator to show all in-scope members as being in their legacy Principal Civil Service Pension Scheme (PCSPS) for service prior to 01/04/2022.

To protect these changes, and to ensure interfaced data is in line with scheme contract requirements, validations are being enhanced to reject any service history data provided within your interface where the reported event is older than 12 months.

The Statement of Work (SOW) process must be used to report any service history events greater than 12 months old.


You must review your interface processes to ensure only service history data events within 12 months of your payroll processing date are provided.


Your first interface after the 30/09/2023.


Under 2015 Remedy (McCloud), all impacted members will become (or will retrospectively become) members of PCSPS for the Remedy period (01/04/2015 – 31/03/2022).

This involves the Scheme Administrator updating the data currently held for active and deferred members who are in scope for Remedy and who transitioned to alpha before 01/04/2022, to reflect a retrospective move from alpha, back to PCSPS. This is called rollback.

To protect these changes, we are enhancing the interface validations to reject any service history data provided in your interface, including deletion records, where the reported service event is older than 12 months.

This will be known as the rolling 12-month cut-off validation.

The pay period end date in your interface control file will be used to assess the 12-month rolling period.

Example 1: reporting a service event

  • A retrospective service history event occurs on your payroll, dated 1st November 2022
  • If you notify the Scheme Administrator of this event in your October 2023 interface, the data will be accepted (dependant on all other validations being passed)
  • If you notify the Scheme Administrator in your November 2023 interface (or later) then this data will be rejected and reported back to you on your Data Validation Report (DVR).

Example 2: reporting a ‘leaver’ by re-supplying the member’s latest open service history line with the end date and end reason populated

  • If you notify the Scheme Administrator of a leaver and the leaver date is within the rolling 12-months cut-off period but the start date is not, this record will pass the new validations because the event being reported is the ‘leaver’ date which is within the cut-off period.
  • However, if you notify the Scheme Administrator of a leaver and the start date and leaver date are not within the rolling 12-months cut-off period, this record will fail the new validations and be reported back to you on your DVR.

On review, if any of these rejected service history records need to be re-supplied to the Scheme Administrator, the statement of work (SOW) process must be followed. They cannot be re-supplied via your monthly interface or the DVR correction process.

Please note: The Scheme Administrator may introduce the 12-month rolling cut-off validation to other interfaced record types e.g. salary, allowance, bonus. You will be informed of any changes via the EPN process.

The Scheme Administrator will review and update the developers guide and the interface validations guidance in due course, to support the above changes. Once the documents have been updated the Scheme Administrator will issue them to the relevant contacts.

Support available

The Scheme Administrator will be allowing employers a 9-month grace period with regards rejections under these validation enhancements so although they will be reported back to you via your DVR, they will not initially count towards your Compliance model error percentage. The grace period also covers SOW charges to load any data rejected by the new validations. For clarity, the SOW process will still need to be followed, it is only the charges that are covered by the grace period.
