WAD: How-to get query name and pass to URL

Question

Hi,
The task: In a BI 7.0 web template - get the technical query name and use that to open a URL in the format http://<MYURL>&DOCUMENTATION=<QUERYNAME>. So:
1) User clicks an icon
2) Get technical name of query
3) Open the documentation for that query using a URL
How can this be done? Do I have to use the Custom Extension web item and implement a new class using the interface IF_BICS_CONS_WEBITEM_CUST_EXIT? If so, do you have an example of how this can be done? OR even better is there an easier way to accomplish this?
Thanks in advance,
Jacob

Hi Daniel,
you could get the query name in ABAP code, also. Here is a snippet from the execute method. The Query name should be in l_sx_view at the end.

TYPE-POOLS: 
  rrx1.
DATA:
  l_string TYPE string,
  l_xml TYPE string,
  l_xml_xstring TYPE xstring,
  l_sx_view TYPE rrx1_sx_view,
* Line Feed, CR
  c_lf TYPE string,
  l_h_lf(2) TYPE x VALUE '0D0A',
  l_r_conv TYPE REF TO cl_abap_conv_in_ce.
* Get the line feed and carriage return for unicode
  l_r_conv = cl_abap_conv_in_ce=>create( input = l_h_lf ).
  l_r_conv->read( IMPORTING data = c_lf ).
  DATA:
  l_t_data_providers TYPE cl_bics_cons_webitem_util=>tn_t_data_provider,
  l_s_data_providers TYPE cl_bics_cons_webitem_util=>tn_s_data_provider,
  l_r_variable_container TYPE REF TO if_ixml_node.
  CLEAR e_xml.
  TRY.
*     All data passed to the webitem exit is hold in I_XML using XML.
*     The XML is UTF-8 encoded. You can convert the UTF-8 xstring
*     to a simple ABAP string by calling the following method:
*     ==================================================================
      CALL METHOD cl_bics_cons_webitem_util=>utf8_xstring_2_string
        EXPORTING
          i_utf8_xstring = i_xml
        RECEIVING
          r_string       = l_xml.
*     The XML includes sections about the used data provider and about the
*     variable container. The following method parses the XML and
*     provides the IF_IXML_NODE instances for data providers and for the
*     variable container.
*     ==================================================================
      CALL METHOD cl_bics_cons_webitem_util=>parse_xml
        EXPORTING
          i_xml                  = i_xml
        IMPORTING
          e_t_data_providers     = l_t_data_providers
          e_r_variable_container = l_r_variable_container.
* 01 Get name of first Data Provider
      READ TABLE l_t_data_providers INDEX 1 INTO l_s_data_providers.
      CALL TRANSFORMATION bics_cons_webitem_filter_by_dp
      PARAMETERS dataprovider = l_s_data_providers-name
      SOURCE XML i_xml
      RESULT XML l_xml_xstring.
      CALL METHOD cl_bics_cons_state_converter=>convert_xml
        EXPORTING
          i_xml     = l_xml_xstring
        IMPORTING
          e_sx_view = l_sx_view.
