Add Manager of Primary contact from agent screen for Helpdesk request

Summary:

I was trying to add the manager of the primary contact in helpdesk request from agent screen.
It was giving me the error "Manager hierarchy is not setup for the primary point of contact". But line manager exists for that employee.

I have added standard "ORA_SVC_HUMAN_RESOURCE_HELP_DESK_AGENT_NG_JOB" role to the agent.

Do I need to add any additional privileges to the agent and helpdesk managers?

I have observed the same issue with Case worker and Case Manager.

Could you please suggest.
