Execute BW query using ABAP

Question

Hello ,
1) I used the function module from this link :
/people/durairaj.athavanraja/blog/2005/12/05/execute-bw-query-using-abap-part-iii
When I run it , I see the metadata correct and this is all. No more data to display.
2) Then I used the code from here :
/people/durairaj.athavanraja/blog/2005/12/05/execute-bw-query-using-abap-part-iii
MOVE: <variable name> TO wa_var-vnam ,
   'I' TO wa_var-sign,
   'EQ' TO wa_var-opt,
   <variable value> TO wa_var-low .
     query_variables       = var
FUNCTION z_test_query.
  FIELD-SYMBOLS: <outtab> TYPE ANY TABLE,
    <l_line>  TYPE ANY,
    <l_field> TYPE ANY.
  TYPE-POOLS: rrx1 .
  DATA: wa_var     TYPE     rrx_var ,
        var TYPE STANDARD TABLE OF rrx_var ,
        xml_out TYPE string ,
        breturn TYPE STANDARD TABLE OF bapiret2 ,
        rpt_tech_id(50) ,
        wa_meta TYPE zbw_query_output_metadata ,
        xslt_error TYPE REF TO cx_xslt_exception ,
        is_fieldcat     TYPE     lvc_s_fcat,
        it_fieldcat       TYPE     lvc_t_fcat,
        new_table  TYPE REF TO data ,
        xslt_message TYPE string ,
        meta TYPE STANDARD TABLE OF zbw_query_output_metadata . " this structure was created in the previous part
*fill all the variables like below.
  MOVE: 'SEM_PSG01/PSG___00000_080_V1' TO rpt_tech_id .
  APPEND wa_var TO var .
  CLEAR :xml_out .
  REFRESH breturn .
  CALL FUNCTION 'Z_QUERY_EXECUTE'
    EXPORTING
      query_name            = rpt_tech_id
    IMPORTING
      xml_out               = xml_out
    TABLES
      return                = breturn
      meta                  = meta
    EXCEPTIONS
      bad_value_combination = 1
      user_not_authorized   = 2
      unknown_error         = 3
      query_not_found       = 4
      OTHERS                = 5.
  CASE sy-subrc .
    WHEN 0 .
      CLEAR: is_fieldcat, wa_meta .
      REFRESH: it_fieldcat .
      LOOP AT meta INTO wa_meta.
        is_fieldcat-fieldname = wa_meta-fieldname.
        is_fieldcat-outputlen = wa_meta-outputlen .
        is_fieldcat-datatype = wa_meta-datatype.
        is_fieldcat-scrtext_l = wa_meta-scrtext_l.
        APPEND is_fieldcat TO it_fieldcat.
        CLEAR : is_fieldcat .
      ENDLOOP .
      IF NOT it_fieldcat[] IS INITIAL .
        CALL METHOD cl_alv_table_create=>create_dynamic_table
          EXPORTING
            it_fieldcatalog = it_fieldcat
          IMPORTING
            ep_table        = new_table.
        ASSIGN new_table->* TO <outtab>.
      ENDIF .
      TRY .
          CALL TRANSFORMATION ('Z_GPS_TR')
          SOURCE XML  xml_out
          RESULT     outtab = <outtab>.
        CATCH cx_xslt_exception INTO xslt_error.
          xslt_message = xslt_error->get_text( ).
      ENDTRY.
    WHEN 1 .
    WHEN 2 .
    WHEN OTHERS .
  ENDCASE .
{ENDFUNCTION.
'Z_GPS_TR' is my transformation (exactly the code from the blog).
'Z_QUERY_EXECUTE' is the function from 1). I did not use variables for the query parameter.
I see with  the debugger that <outtab> is filled corectly, with the values from my query.  Still , the function, when is runed normally, does not display anything.
3) If I run only the transformation Z_GPS_TR alone, it says invalid source XM source file.
Please, some suggestion? I don't know hot to proceed.
Many thanks.
