Conditional Sum and look at next record

Question

First off, here is an example XML structure
<DATASET>
<DATASET_ROW>
<DEPARTMENT>1</DEPARTMENT>
<FEE>30</FEE>
<DIVISION>Displayed Title</DIVISION>
</DATASET_ROW>
<DATASET_ROW>
<DEPARTMENT>1</DEPARTMENT>
<FEE>20</FEE>
<DIVISION>Displayed Title2</DIVISION>
</DATASET_ROW>
<DATASET_ROW>
<DEPARTMENT>1</DEPARTMENT>
<FEE>40</FEE>
<DIVISION>Displayed Title3</DIVISION>
</DATASET_ROW>
<DATASET_ROW>
<DEPARTMENT>2</DEPARTMENT>
<FEE>30</FEE>
<DIVISION>Displayed Title 5</DIVISION>
</DATASET_ROW>
<DATASET_ROW>
<DEPARTMENT>2</DEPARTMENT>
<FEE>80</FEE>
<DIVISION>Displayed Title 6</DIVISION>
</DATASET_ROW>
<DATASET_ROW>
<DEPARTMENT>3</DEPARTMENT>
<FEE>90</FEE>
<DIVISION>Displayed Title 7</DIVISION>
</DATASET_ROW>
<DATASET_ROW>
<DEPARTMENT>3</DEPARTMENT>
<FEE>90</FEE>
<DIVISION>Displayed Title 8</DIVISION>
</DATASET_ROW>
<DATASET_ROW>
<DEPARTMENT>4</DEPARTMENT>
<FEE>30</FEE>
<DIVISION>Displayed Title 9</DIVISION>
</DATASET_ROW>
</DATASET>
Is there any way to get a sum of a field grouped by two different fields? Example in my RTF I have a repeating group based on DIVISION which inserts section breaks. Using the example I have posted here what I have in my RTF template is a sum of FEE (assume there are multiple records for DIVISION though only 1 is shown here) that displays on every page for the current group. Each DIVISION is printed on its own page. However, at the end of each DEPARTMENT, I also need to print a summary total of the sum of FEE over all records for that DEPARTMENT on the same page as the last page of the last DIVISION.
So far, I have been able to get it to do the subtotals for each DEPARTMENT as they are within the scope of my loop. The tricky part I am unsure of how best to go about doing is getting and displaying the conditional grand total. My initial idea was to use a variable and do it manually in my template but then I relaized I did not know how to find out if the next record was the first record in the next Department or not. In this case, I am hoping to stick within the realm of using straight SQL Query as my datasource because its already done. The other option I considered was nested loops and a data template but then I realized that I wasn't too sure about manually inserting the section breaks.
Any thoughts?

Yes, you can do that,
Pass me the template and XML :)
<?if:position() = last()?>
Last Record
<? end if ?>
then display the sub-total for department at the last division.
This link , gives you idea of , how to display at the last
