How to enable the Role approvers visible in the access request in 10.1?

Hi Guys,

I have raised a GRC request, and when i open the GRC request #1234 i can see the roles added for the provision, but the appropriate role approvers are not visible for each role. How to enable this functionality?

Scenario is i dont have access for administration in request search, but i have provisioning status as success and not processed and i want to see the role approvers who are responsible for roles.

How to make visible role approvers for each role? and also is there is any table i can see this?

Thanks in advance.
