Role - Cost Center Manager

[Martinek, Jerry]

Hi, I would like to know whether SAP provides a standard role to find a cost
center manager via a personal number or user id?
 
I tried using role 3100013 but I couldn't get it return anything. Could this
mean that this particular functionality is not active at our site? I used a
number of different methods to test this role but they all came back with
the same results.
 
I also coded a custom program that called RH_GET ACTORS with the mentioned
role and required input parameters but that didn't work.
 
Has anyone written similar custom roles or can anyone provide any hints?
 
Regards,
