Reporting out multiple lookup rows for one fact row. NON-Aggregating

Question

Hi,
I have a situation where I have multiple Look Up rows for one fact row. I want to report them out so that I get One row with the Look Up and Fact information in it and the next row with Just the Look Up information in it.
The version of Oracle I'm using is 9.2.0.6.0.
Look Up Table
Deal Order Number     Partial Order ID     INVENTORY_ITEM_ID     MANUFACTURER_DESCRIPTION
639416-1                1                     43601                     Check Point
639416-1                1                     98809                      Nokia
637260-1                 1                     56657                   IBM
637260-1                 1                     35467                   QuantumFact Table
Deal Order Number     Partial Order ID     Cost
639416-1                 1                     3825.3
637260-1                  1                   3610.8Desired result:
Deal Order Number     Partial Order ID     MANUFACTURER_DESCRIPTION     Cost
639416-1                    1                        Check Point            3825.3
639416-1                     1                         Nokia
637260-1                     1                         Ibm                   3610.8
637260-1                     1                         QuantumBasically I'd like the ability to report out every row of my report with the first row containing the Fact Data and then the following rows containing the Look Up data that are also associated with that fact column but not report the data.
I'm doing this because there's Grand totaling at the bottom of the report that I don't want to mess with.
Plus instead of concatenating the Look Up values together, I need to show them in their own cells in their own rows for view ability.
I think an Analytic function might take care of this but I'm not sure how. Can anyone help?
Thanks in Advance!

Hi,
Join the two tables as you normally would.
You're right about analytic functions being useful. The anaylytic ROW_NUMBER function can number each row of the join, with a separate count for each unique id from lookup.
Use a CASE statement to display certain items from fact when ROW_NUMBER retuns 1, and hide them otherwise.
SELECT     f.order_number
,     f.partial_order_number
,     l.manufacturer_description
,     CASE
          WHEN     ROW_NUMBER () OVER
                    ( PARTITION BY     f.order_number
                      ,          f.partial_order_number
                      ORDER BY     l.manufacturer_description
                    ) = 1
          THEN     cost
     END     AS cost_col
FROM     fact     f
JOIN     lookup     l     ON     f.order_number          = l.order_number
               AND     f.partial_order_number     = l.partial_order_number
ORDER BY     f.order_number
,          f.partial_order_number
,          l.manufacturer_description
;
