so basically i would first denormalize the data using the pivot column and then use min and max to get the slot_start and slot_end.
But then i
can get the min and max ... but not the orignal values as well.
Any thoughts would be appreciated.
Thanks

If you want to end up with one row per slot per datasource etc, and you want the min and max slots that have the same value as the current slot, then you probably need to be using analytic functions, like:
with t as
(SELECT 1 datasource,101    INTEGRATIONID, 201111     slotdate, 100    SLOT1, 100        SLOT2,    200    slot3, 100    slot4, 100    slot5, 100    slot6, 300    slot7, 300    slot8, 300    slot9, 300 slot10 FROM DUAL  union all
SELECT 1,    101,    2011112,    200,    200,    200,    200,    100,    100,    100,    100,    200,    300 FROM DUAL),
UNPIVOTED AS
(SELECT DATASOURCE,INTEGRATIONID,SLOTDATE,1 SLOT,SLOT1 SLOT_VALUE
FROM T
UNION ALL
SELECT DATASOURCE,INTEGRATIONID,SLOTDATE,2 SLOT,SLOT2
FROM T
UNION ALL
SELECT DATASOURCE,INTEGRATIONID,SLOTDATE,3 SLOT,SLOT3
FROM T
UNION ALL
SELECT DATASOURCE,INTEGRATIONID,SLOTDATE,4 SLOT,SLOT4
FROM T
UNION ALL
SELECT DATASOURCE,INTEGRATIONID,SLOTDATE,5 SLOT,SLOT5
FROM T
UNION ALL
SELECT DATASOURCE,INTEGRATIONID,SLOTDATE,6 SLOT,SLOT6
FROM T
UNION ALL
SELECT DATASOURCE,INTEGRATIONID,SLOTDATE,7 SLOT,SLOT7
FROM T
UNION ALL
SELECT DATASOURCE,INTEGRATIONID,SLOTDATE,8 SLOT,SLOT8
FROM T
UNION ALL
SELECT DATASOURCE,INTEGRATIONID,SLOTDATE,9 SLOT,SLOT9
FROM T
UNION ALL
SELECT DATASOURCE,INTEGRATIONID,SLOTDATE,10 SLOT,SLOT10
FROM T)
select DATASOURCE,INTEGRATIONID,SLOTDATE,slot,slot_value,min(slot) OVER (partition by datasource,integrationid,slotdate,rn) minslot,
    max(slot) OVER (partition by datasource,integrationid,slotdate,rn) maxslot
FROM   
  select DATASOURCE,INTEGRATIONID,SLOTDATE,max(rn) over (partition by datasource,integrationid,slotdate order by slot) rn,slot,slot_value
  FROM
    (SELECT DATASOURCE,INTEGRATIONID,SLOTDATE,slot,slot_value,
          case when row_number() over (partition by datasource,integrationid,slotdate order by slot) = 1 or
          lag(slot_value) over (partition by datasource,integrationid,slotdate order by slot) <> slot_value
              then row_number() over (partition by datasource,integrationid,slotdate order by slot)
              ELSE null
              END rn
    from unpivoted
order by DATASOURCE,INTEGRATIONID,SLOTDATE,slot
