Webservice/BAPI to create a Project (PS) based on a Project Templates

Hello,

i want to create Projects (in SAP ERP) based on Templates using webservices.

In SAP ERP PS (TNC: CJ20N) the function is called "copy project" - Field: Standard Project Definition.

ProjectERPCreateRequestConfirmation_In_V1 does not provide this functionality.

Here i can only create completly new projects.

There is no potential input field for a project template (e.g.StdProjectID or else).

Does anybody know a Webservice or a BAPI with that function?

Greetings,

Oliver
