Inactive Departments and Attrition Reporting Error

Summary

Issue once departments are made inactive we are no longer able to report on leavers.

Following a restructure we have made a number of departments inactive and removed from the dept tree however now employees who were aligned to these departments don't appear on leavers reports.

Does anyone know of any workarounds or how to overcome this issue either within reporting or within workforce structures itself?

Thanks
