I have completed the below query to return process time for our goods in activity and also then used a case when <'24:00:00' for SLA HIT or SLA FAIL

problem i have is that the formula is returning incorrectly

1-2 hours SLA HIT
2-10 hours SLA FAIL
11-24 Hours SLA HIT
>24 hours SLA FAIL

i dont understand why > 2 <10 is SLA FAIL

select

/*it.site_id,
it.code,
it.from_loc_id,
it.to_loc_id,
it.sku_id,
it.tag_id,
to_char(it.dstamp, 'DD-MON-YYYY') "DATE",
it.update_qty*/

to_char(it.dstamp, 'DD-MON-YYYY') "DATE",
it.sku_id "SKU",
it.client_id "CLIENT",
it.tag_id "TAG",
it.update_qty "QTY",
to_char(it.dstamp, 'DD-MON-YYYY HH24:MI:SS') "RECEIPT",
to_char(it2.dstamp, 'DD-MON-YYYY HH24:MI:SS') "PUTAWAY",
LibDate.ConvertSecsToHMS
(LibDate.IntervalSecond
((CASE when it2.code = 'Putaway' then it2.dstamp else null end)
-
(CASE when it.code = 'Receipt' then it.dstamp else null end))) "PROCESS TIME",

case when LibDate.ConvertSecsToHMS (LibDate.IntervalSecond (MAX (it2.dstamp) - MAX (it.dstamp))) < '24:00:00' then 'SLA HIT' else 'SLA FAIL' end "SLA ACHIEVEMENT"


from Inventory_transaction it

full outer join inventory_transaction it2 on it.tag_id = it2.tag_id

where
it.site_id like 'TIC'
and
it.client_id in ('P82GB72','P82SL82')
and
it.code like 'Receipt'
and
it2.code like 'Putaway'
and
(trunc(it.dstamp,'DDD') >= '01-NOV-2012'
and
trunc(it.dstamp,'DDD') < '12-NOV-2012')


group by it.code, it2.code, it.dstamp, it2.dstamp, it.tag_id, it.update_qty, it.sku_id, it.client_id
order by it.dstamp asc

Your case expression should be something like shown below. The way you have it now, it categorizes everything that is less than 24 hours into one single category.

Couple of things to note:

a) It would be more efficient to compare seconds rather than do a conversion to HMS. Per row function calls are usually expensive.

b) The BETWEEN clause I am using is inclusive, so for example, between 1:00:00 and 2:00:00 will include both 1:00:00 and 2:00:00 (i.e., a closed set).
CASE 
    WHEN LibDate.ConvertSecsToHMS (LibDate.IntervalSecond (MAX(it2.dstamp) - MAX(it.dstamp))) 
         BETWEEN '1:00:00' AND '2:00:00' 
         OR 
         LibDate.ConvertSecsToHMS (LibDate.IntervalSecond (MAX(it2.dstamp) - MAX(it.dstamp))) 
         BETWEEN '11:00:00' AND '24:00:00'  THEN 'SLA HIT'
    ELSE 'SLA FAIL'
END "SLA ACHIEVEMENT"

my original post may have come across incorrectly

i do want < 24:00:00 SLA HIT
> 24:00:00 SLA FAIL

i have modified the statement to between 00:00:01 to 24:00:00 but still getting the same problem

anything >2 <10 is coming up as SLA fail

What I posted earlier should have given "SLA HIT" for any duration >= 1:00:00 and <= 2:00:00 or duration >= 11:00:00 and <= 24:00:00 and "SLA FAIL" for everything else. If that is not what you require, change the numbers accordingly.

Are you using Microsoft SQL Server? If you are using Oracle, I don't know the behavior of the case expression, or even whether the syntax is supported the same way. This forum is for Microsoft SQL Server, so if you are on another DBMS, you would get better and faster responses at a forum such as dbforums.com
