I think this might be a cleaner solution:
with DATE_ORDERED as (
select row_number() over(
partition by PRODUCT#,
date(TIME_STAMP)
order by TIME_STAMP desc
) as SEQ,
X.*
from PRODFA.AVLAUDP X
)
select * from DATE_ORDERED where SEQ = 1 order by PRODUCT, TIME_STAMP
Tim.

Thanks Paul
This is what I ended up with
with itemsavail as
(SELECT
PRODUCT#, AVAIL_QTY, TIME_STAMP, date(TIME_STAMP) as AADATE
FROM PRODFA.avlaudp
WHERE date(TIME_STAMP) between
'2020-11-06' and '2020-11-29'
order by date(TIME_STAMP), PRODUCT#),
itemshighest as
(select z.PRODUCT#, z.AADATE, max(z.TIME_STAMP) as Hights
from itemsavail z
group by z.PRODUCT#, z.AADATE
order by z.PRODUCT#, z.AADATE)
select a.PRODUCT#, a.AADATE, a.Hights, b.AVAIL_QTY
FROM itemshighest A LEFT join itemsavail b on
a.PRODUCT# = b.PRODUCT# and
a.AADATE = b.AADATE and
a.Hights = b.TIME_STAMP
order by a.AADATE, a.PRODUCT#

Thanks for your reply Paul
I had an epiphany just after I sent the e-mail and I am heading down this same direction The one thing missing from your example is the highest timestamp for the day, not just the highest timestamp

something like this:
select product, available_qty, time_stamp from myfile a where (product, time_stamp) in ( select product, max(time_stamp) from myfile b where b.product = a.product group by product);

Hi everyone
We are on V7r3
We have a file that is an audit of the available quantity of products The fields are Product, time_stamp, Available_Qty I need to obtain the LAST record for a product within the same day For example Product time_stamp Available_Qty
5
2020-11-06-19.19.33.418000
6,469
6
2020-11-06-19.19.17.852000
1,645
35
2020-11-06-19.20.34.152000
1,595
65
2020-11-06-19.20.14.041000
1,522
70
2020-11-06-19.19.36.783000
4,433

2020-11-06-22.03.12.252000
4,431
91
2020-11-06-19.20.23.527000
8,890
Which would then result in
Product
time_stamp
Available_Qty
5
2020-11-06-19.19.33.418000
6,469

2020-11-06-19.19.17.852000

2020-11-06-19.20.23.527000
8,890
Hope this makes sense
