How can I pass org structure from C4C to ERP

Hi,

We have a client requirement to pass org structure as it is from C4C to ERP.

Is there any webservice available to pass the org structure?

In C4C which BO can be queried to access the org structure data?

I tried querying BusinessPartnerHierarchy BO, but it does not return any resultset. Will this BO give me the entire C4C org structure?

Kindly see my code below:

Please help me. As we are expected to deliver this ASAP.

Thanks & Regards,
