Hi,
After looking through the various SAP documents and playing with the RESTful web services API, it seems that you cannot retrieve the entire hierarchy without making a substantial number of calls. Is it possible to retrieve the entire hierarchy in a single call or only a few calls (one for each level)? I had no luck trying to submit multiple paths in a single request and unless the response changes, it does not look like the response would distinguish between the multiple paths with the returned values.
Thanks
