SQL/HIVE - resolve issue (small change) - Partition - sql

Question

I have the below code, which mostly works correctly with some other scenarios I tested.
However, for the example below I am trying to count the number for N-CO (non completions) until completion but it return 5 instead of 3.
And i am trying to create another column to count the PARTIALLY which is 2.
Any once have some input as to why?
What do I need to change?
CREATE TABLE #temp
(
Identifier varchar(20)NOT NULL
,CreatedDate DATETIME NOT NULL
,CompletedDate DATETIME NOT NULL
,SN_Type varchar(20) NOT NULL
,SN_Status varchar(20) NOT NULL
)
;
INSERT INTO #temp
VALUES('64074558792','20160729','20160805','Re-Activattion','N-CO');
INSERT INTO #temp
VALUES('64074558792','20160729','20160805','Re-Activattion','PARTIALLY');
INSERT INTO #temp
VALUES('64074558792','20160809','20160809','Re-Activattion','PARTIALLY');
INSERT INTO #temp
VALUES('64074558792','20160810','20160810','Re-Activattion','N-CO');
INSERT INTO #temp
VALUES('64074558792','20160812','20160812','Re-Activattion','N-CO');
INSERT INTO #temp

INSERT INTO #temp

ORDER BY rn;
DROP TABLE #temp

Answer 1

select Identifier
,COMP_id
,count(case when SN_Status = 'N-CO' then 1 end) as count_N_CO
,count(case when SN_Status = 'PARTIALLY' then 1 end) as count_PARTIALLY
,count(case when SN_Status = 'COMP' then 1 end) as is_COMP
from (select Identifier
,SN_Status
,count(case when SN_Status = 'COMP' then 1 end) over
(
partition by Identifier
order by CreatedDate, case when SN_Status = 'COMP' then 1 else 0 end, CompletedDate
rows between unbounded preceding and 1 preceding
) + 1 as COMP_id
from #temp
) t
group by Identifier
,COMP_id
+-------------+---------+------------+-----------------+---------+
| Identifier | COMP_id | count_N_CO | count_PARTIALLY | is_COMP |
+-------------+---------+------------+-----------------+---------+
| 64074558792 | 1 | 3 | 2 | 1 |
| 64074558792 | 2 | 1 | 0 | 0 |
