Repeating frame not visible when the query returns no rows

Question

I've developed a report whose output looks like this:
Subinventory | Part Code |Part Description |Ordered Qty | Received Qty
Mentone St | BATT | non serialised item | |
Mentone St | SONY | spare parts MIN MAX | 30| 0
In the above report
subinventory, Part Code, Part description are in one repeating frame and Ordered and received qty are in other repeating frame.
for a perticular part code there may not be ordered or received quantities. Means the seond query fetches no rows for the perticulat partcode. In that case report is showing null(blank) but I want to print ZERO there.
If I use NVL in the query it'll effect only when the query fetches some rows.
I've tried with formula columns. for example in the formula column
IF :ordered_qty IS NULL THEN
v_ordered_qty :=0;
ELSE
v_ordered_qty := :ordered_qty;
END IF;
return(v_ordered_qty);
I've assigned this formula column as source to the Ordered Qty Filed. Then also its not working.
Any help in this regards is highly apprecialted

may be you can modify your code like below:
SELECT i.subinventory, i.part_code, i.part_description, i.min_qty, i.max_qty,
       NVL (j.quantity, 0) ordered_qty,
       NVL (j.quantity_delivered, 0) received_qty
  FROM (SELECT DISTINCT c.secondary_inventory subinventory,
                        b.segment1 part_code, b.description part_description,
                        c.min_minmax_quantity min_qty,
                        c.max_minmax_quantity max_qty, b.inventory_item_id,
                        b.organization_id
                   FROM mtl_system_items_b b,
                        mtl_item_sub_inventories_all_v c
                  WHERE b.inventory_item_id = c.inventory_item_id
                    AND b.organization_id = c.organization_id
                    AND UPPER (c.secondary_inventory) =
                           NVL (UPPER (DECODE (:p_sub_inv,
                                               'ALL', '',
                                               :p_sub_inv
                                UPPER (c.secondary_inventory)
                               )) i,
       (SELECT   mtrl.inventory_item_id, mtrl.organization_id,
                 mtrl.to_subinventory_code,
                 NVL (SUM (mtrl.quantity), 0) quantity,
                 NVL (SUM (mtrl.quantity_delivered), 0) quantity_delivered
            FROM mtl_txn_request_lines mtrl, mtl_system_items_b msi
           WHERE mtrl.inventory_item_id = msi.inventory_item_id
             AND mtrl.organization_id = msi.organization_id
             AND mtrl.reference_type_code = 2
             AND UPPER (mtrl.to_subinventory_code) =
                    NVL (UPPER (DECODE (:p_sub_inv, 'ALL', '', :p_sub_inv)),
                         UPPER (mtrl.to_subinventory_code)
             AND TRUNC (mtrl.creation_date)
                    BETWEEN NVL (TRUNC (TO_DATE (:p_from_date,
                                                 'yyyy/mm/dd hh24:mi:ss'
                                 TRUNC (mtrl.creation_date)
                        AND NVL (TRUNC (TO_DATE (:p_to_date,
                                                 'yyyy/mm/dd hh24:mi:ss'
                                 TRUNC (mtrl.creation_date)
        GROUP BY mtrl.inventory_item_id,
                 mtrl.organization_id,
                 mtrl.to_subinventory_code) j
WHERE i.inventory_item_id = j.inventory_item_id(+)
       AND i.organization_id = j.organization_id(+)
