One record in the master Query, many in the child. Data Template Woes

Question

Hi Folks.
Can't get my head around this and I wonder if anyone could shed some light.
I have the following simple data template set up.
<dataTemplate name="Invoice" description="Default Invoice" version="1.0">
<parameters>
<parameter name="P_INVOICE_ID" dataType="character"/>
</parameters>
<dataQuery>
<sqlStatement name="Q1">
<![CDATA[select invoice_id                  
             from vw_invoice_summary
             where invoice_id IN (:P_INVOICE_ID)]]>
</sqlStatement>
<sqlStatement name="Q2">
<![CDATA[Select invoice_line_item_id
            from invoice_line_item
             where invoice_id = :invoice_id]]>
</sqlStatement>
</dataQuery>
</dataTemplate>
When I set the Parameter to a valid invoice ID, I only get the following result. There should be two sets of data being returned. One set with the single parent record and the second set with roughly thirty records.
<?xml version="1.0" encoding="UTF-8" ?>
- <INVOICE>
<P_INVOICE_ID>16946</P_INVOICE_ID>
- <LIST_Q1>
- <Q1>
<INVOICE_ID>16946</INVOICE_ID>
</Q1>
</LIST_Q1>
</INVOICE>
Where is the Q2 data set? Can anyone see what I'm doing wrong? Can anyone point me to the right section of the documentation? I have read and re-read the BIP Users Guide (Section 4) but I guess I must be missing something.
Any help gratefully received.
Many thanks.

Hi Ike.
Quick question for you.
I have the Groups defined and my template is working well with them.
My final sticking point is the incorporation of a parameter.
My template starts like this...
<dataTemplate name="Invoice" description="Invoice">
<parameters>
<parameter name="invoiceid"/>
</parameters>
<dataQuery>
<sqlStatement name="Q1">
<![CDATA[select * from vw_invoice
                   where invoice_id IN(:invoiceid)]]>
</sqlStatement>
<sqlStatement name="Q2">
<![CDATA[Select.................
I am trying to call it using a SOAP Envelope containing this...
<parameterNameValues>
<item>
<name>invoiceid</name>
<multiValuesAllowed>true</multiValuesAllowed>
<values>
<item>18421,16946,19178</item>
</values>
</item>
</parameterNameValues>
The result being recorded in BIP Schedules is "Data not defined".
What am I doing wrong? Any thoughts?
Kind regards.
Simon.
