Hi ,

We are looking to create a custom admin role which can only manage delegation rules for other workers. Currently this is done using two ways through person management> user account and quick actions> manage user accounts under my client group.

we do not want to give an admin access to other extra area for HR or security. We have tried adding the seeded duty role,

ORA_PER_MANAGE_APPROVAL_DELEGATIONS

ORA_PER_VIEW_APPROVAL_DELEGATIONS

but still it is not working.
