Is there a limit for the number of direct reports who can be reassigned using the Reassign Directs section?

Yes, there’s a limit of 997 direct reports who can be reassigned to other managers. If the number exceeds this limit, then the reassign process doesn’t succeed in the UI.

It’s recommended not to use the Reassign Directs section if the number of reports are more than 200 to avoid performance issues. If you need to reassign more than 200 reports, you can use HCM Data Loader.
