Fetching drill filter values for reports having prompt using webi-restful sdk?

Hi,

following the document for SAP restful services i am able to fetch the drill filters on the report but the when i try to get the values in the filter by getting into the details of a filter i am only getting the ID not the values.

When i using the reports without any prompts i am able to get the filter values within the filter only. the code i am using to get the filter is below.

  //get

  String url = baseURL + "/raylight/v1/documents/"+ documentId+"/reports/"+reportId+"/filters";

  HttpGet post = new HttpGet(url);

  post.setHeader("Content-Type", "application/xml");

  post.setHeader("Accept", "application/xml");

  post.setHeader("X-SAP-LogonToken", logonToken);

  HttpResponse response = client.execute(post);

  Header headers[] = response.getAllHeaders();

  for (int i = 0; i < headers.length; i++) {

  Header header = headers[i];

  System.out.println(header.getName() + "=" + header.getValue());

  }

  BufferedReader rd = new BufferedReader(new InputStreamReader(response

  .getEntity().getContent()));

  String line = "";

  while ((line = rd.readLine()) != null) {

  writer.println(line);

  //System.out.println(line);

  }

  writer.close();

  }

I am unable to understand the behavior to get the filters with and without prompts. please give some suggestion on it.

Thanks and Regrds
