End-date Accrual plan

Summary:

We have an accrual-plan running from 1th of june untill 31th of may next year based on hours. As from June 1th 2023 we have a new plan based on days, so we end-dated the enrollments for all employees and now want to end date the plan.

This results in an error message: "You can't delete this plan because it has enrollment data associated with it. (ANC-3405038)"

Making plan inactie does not work, end-date the eligibility on participation tab does not show any end date

What option are left to keep history but remove plan from views and reports?
