Start process with processstartmanager and context elements

Hi guys,

we want to start our process with the new BPM API (http://help.sap.com/saphelp_nw73/helpdata/de/77/2943a3456147d69cd637801d3b3f3d/content.htm).

Until now we are starting the process via Webservice.

I have problems to commit the right paramter to the processStartDataObject.

The process has to get nested context elements like following:

- Auftragsdaten

- - Kopfdaten

- - - - Name

- - - - Adresse

- - - - PLZ

- - - - Ort

- - Detaildaten

- - - - Nummer

- - - - Beschreibung

- - - - Bezeichnung

- - - - Datum

With the new BPM API i can set a String, int ... but not these context elements.

Do you have any idea?

Thanks,

Martin
