How to get the Vendor and DC Name of an BPM Process

Hello,

i am building a small reporting application for BPM. Now to get the reporting datasource of a process it requires the Vendor and dc name of that process. I am stuck right now since i don't know how to get this information.

I can get ProcessDefinition and ProcessInstance objects from the SAP BPM API. Then i want to show the processes to the User in the UI. The user can choose a process now and next step would be to get the ReportingDatasource object for that chosen process. But the method requires DC and vendor name of the process. Is there any other api there to get this information?

Thanks for help.
