Suppliers report

Question

Hi, all,
today I have received a simple [first look] task.
Daily upload on FTP a suppliers report with items sold.
Within the sold items, there are concession and own-bought, the report is necessary only for the concession suppliers. The concession flag is suppliers attribute, so concession supplier can be defined on the suppliers system.
Sales and Suppliers are different systems (data sources) and different databases MSSQL and Oracle.
Problem:
1. The using of the ":item" bind variable in the suppliers request creates additional group <G_ITEMS>, i.e. each item will have <G_SUPPLIER> group and than each <G_SUPPLIER> the <G_SALES> group. Seems that this not acceptable.
<DTEMPLATE>
<LIST_G_ITEMS>
<G_ITEMS>
<CITEMS>100000008</CITEMS>
<LIST_G_SUPPLIER>
<G_SUPPLIER>
<CSUPPLIER>Supplier1</CSUPPLIER>
<CSUPPLIERD>SupplierNAME</CSUPPLIERD>
<LIST_G_SALES>
<G_SALES>
<SITEMS>100000008</SITEMS>
<SUNITS>8</SUNITS>
2. How to write the delivery query if items and suppliers are from different data sources?
3. Database links are not preferred.
Any suggestions?
Forgotten: Using the BIP EE Standalone 10.3.4.1 with march 31 2010 update included.

Hi,
thanks for your time and support:
what I'm doing wrong?
1. Data sources specified;
2. DT
*<dataQuery> -part:*
<sqlStatement name="Q_ITEMS" dataSourceRef="MSSQL">
<![CDATA[
select distinct items from table1
]]>
</sqlStatement>
<sqlStatement name="Q_SUPPLIER" dataSourceRef="ORCL">
<![CDATA[
select s.ITEM item2
, s.supplier ip
     , s.sup_name sup_name
from item_sups s
where s.item = :items
]]>
</sqlStatement>
<sqlStatement name="Q_SALES" dataSourceRef="MSSQL">
<![CDATA[
          select item,
               tran_date,
               units,
               retail
               from tran_data if1
               where if1.item = :item2
               ]]>
</sqlStatement>
*<dataStructure> - part*
1st type - which returns really strange structured data, each item group has sub-group with supplier, and supliers sub-group with sales.
<dataStructure>
          <group name="G_ITEMS" datatype="varchar2" source="Q_ITEMS">
               <element name="CITEMS" dataType="varchar2" value="items"/>
          <group name="G_SUPPLIER" datatype="varchar2" source="Q_SUPPLIER">
          <element name="ITEM" dataType="varchar2" value="item2"/>
               <element name="ITEM_Supplier" dataType="varchar2" value="IP"/>
               <element name="sup_name" dataType="varchar2" value="sup_name"/>
               <element name="CITEMS_G" dataType="varchar2" value="G_ITEMS.items"/>
          <group name="G_SALES" datatype="varchar2" source="Q_SALES">
          <element name="S_ITEM" dataType="varchar2" value="item"/>
               <element name="S_DATE" dataType="varchar2" value="TRAN_DATE"/>
               <element name="S_UNITS" dataType="varchar2" value="units"/>
               <element name="S_RETAIL" dataType="varchar2" value="total_retail"/>
          </group></group></group>
2nd type - which returns only single suppliers information (the supplier information of the last item from items group), taking into account that 4 presented item has 4 different suppliers.
<dataStructure>
          <group name="G_ITEMS" datatype="varchar2" source="Q_ITEMS">
               <element name="CITEMS" dataType="varchar2" value="items"/>
          </group>
          <group name="G_SUPPLIER" datatype="varchar2" source="Q_SUPPLIER">
          <element name="ITEM" dataType="varchar2" value="item2"/>
               <element name="ITEM_Supplier" dataType="varchar2" value="IP"/>
               <element name="sup_name" dataType="varchar2" value="sup_name"/>
               <element name="CITEMS_G" dataType="varchar2" value="G_ITEMS.items"/>
          </group>
          <group name="G_SALES" datatype="varchar2" source="Q_SALES">
          <element name="S_ITEM" dataType="varchar2" value="item"/>
               <element name="S_DATE" dataType="varchar2" value="TRAN_DATE"/>
               <element name="S_UNITS" dataType="varchar2" value="units"/>
               <element name="S_RETAIL" dataType="varchar2" value="total_retail"/>
          </group>
