Plan Maintenance (PM00) - risk analysis no results

I am working with on risk remediation assignment things are going well with other areas like FI, PTP, HR & Basis etc but I struck with Plan Maintenance (PM00). Here I need you help and expert opinion to guide me in right direction.

I tried different ways to analyse but no outcome:

1). I ran risk analysis on role level with given list of roles,

2). I ran risk analysis by business processes,

3). I tried batch risk analysis on user level and role level but GRC box is not showing me risk.

BC set “GRAC_RA_RULESET_SAP_R3” is active. Its GRC 10, SP-level: 16

Waiting for you valuable contribution and thanks in advance for your help.

Thanks and Regards.
