No Approver found in the Access request for Risk owners?

Hi Team,

We have defined ABAP Class based for Agent Rule ZCL_GRAC_WFA_RISK_OWNER, and the Risk owners are also maintained in the AC table in Set-up, but after submitting the access request there are SOD voilations,Detour condition GRAC_MSMP_DETOUR_SODVIOL is satisfied , so the request is routed to ROLEAPP_SOD_PATH and parallely routed  SODVIOL_DETOUR_PATH6,

Once the role owner approvers the request, and escape route applied at SODVIOL_DETOUR_PATH6  as  No approver found.

But the Risk owners are defined in the AC Owner table.

Can anybody help with this, as why escape path is applied even after maintaining Risk owners?

Regards,

Sindhu
