Hi Team,

Greetings!

We have an active employee in the application. This person does not show up under the proposed manager while transferring the direct reports

Navigation:

My client groups > Quick Actions ? Change manager / Direct reports

The same works when we check from the employment page.

All the processes (ESS jobs) have been already run.

Has anyone come across this issue? How was this resolved? Is this issue related to security?
If anyone has any inputs around the same - please share.
