LEFT OUTER JOIN MATCHING - sql-server

Question

I have the following query, I modified it to be able to look in a new table called Futuredial_Validation, I wrote all the conditions and the joins but its still don't looking in the table, just in the one called cellscripter, the rest of the query works, I really appreciate any help, thanks:
SELECT row_number() OVER (ORDER BY wms_us.wms_us.rrno.rrdate, wms_us.wms_us.rrno.pono, wms_us.wms_us.transferboxdet.meidhex, att.Date_cleared) AS ROW_ID,
wms_us.wms_us.rrno.pono AS ATT_PO,
wms_us.wms_us.rrno.rrdate AS Received_Date,
CASE
WHEN (wms_us.wms_us.model.modeldesc = 'MIXED')
THEN wms_us.wms_us.transferboxdet.basemodel
ELSE wms_us.wms_us.model.modelbase
END AS Model,
CASE
WHEN LEN(wms_us.wms_us.transferboxdet.meidhex) >= 15
THEN LEFT(wms_us.wms_us.transferboxdet.meidhex, 14)
ELSE wms_us.wms_us.transferboxdet.meidhex
END AS IMEI,
/*Check in Futerdial else obtain the values from cellscripter*/
CASE
WHEN (Future.[Error Code] = '1')
THEN Future.LocalTime
ELSE att.Date_cleared
END AS Date_cleared,
CASE
WHEN (Future.[Error Code] = '1')
THEN 'PASS'
ELSE att.Result
END AS Result

LEFT OUTER JOIN Futerdial.dbo.Futuredial_Validation AS Future

LEFT OUTER JOIN DRSCSQLQADB01.att_view2.dbo.attview2 AS att

WHERE (wms_us.wms_us.rrno.rrdate > '2016-12-01')

Answer 1

Most likely: either your join specification is not working or the case expression for the [Error Code] is not correct.
Check if you get any values for [Future_imei] and [Error Code] with this:
select
row_id = row_number() over (
order by rrno.rrdate
, rrno.pono
, tbdet.meidhex
, att.Date_cleared)
, att_po = rrno.pono
, Received_Date = rrno.rrdate
, Model=case
when (m.modeldesc = 'mixed')
then tbdet.basemodel
else m.modelbase
end
, imei=case
when len(tbdet.meidhex) >= 15
then left(tbdet.meidhex, 14)
else tbdet.meidhex
end
, [Future_imei] = Future.imei
, Future.[Error Code]
, Date_cleared=case
when (Future.[Error Code] = '1')
then Future.LocalTime
else att.Date_cleared
end
, [Result]=case
when (Future.[Error Code] = '1')
then 'pass'
else att.Result
end
from wms_us.wms_us.transferboxdoc as tbdoc
inner join wms_us.wms_us.transferboxdet as tbdet
on tbdoc.transferboxdocid = tbdet.transferboxdocid
inner join wms_us.wms_us.rrno as rrno
