I have the table below:
CREATE TABLE "XXSAMPLE2"

It seems it's doing a Merge Join Cartesian with itself:

Do I need to Add more conditions to the UNPIVOT ?

The main issue is that you're unpivoting three times, and aggregating at the wrong level - aggregation shouldn't really be necessary at all, at least with the sample data.
You also need to exclude some of the values your current query returns - the functional amounts when functional box is null.
I think this non-union query gets only the data you want:
select jg_info_n11 invoice_id
, jg_info_v21 invoice_type
, jg_info_v32 currency_code
, case when jg_info_v14 = 'tns:' then null
else jg_info_v14
end as v14_box
, case when jg_info_v14 = 'tns:' then null
else jg_info_n15
end as v14_amount
, case when jg_info_v14 like 'tns:P_14%' and jg_info_v32 <> 'PLN' then jg_info_v14||'W'
end as v14_func_box
, case when jg_info_v14 like 'tns:P_14%' and jg_info_v32 <> 'PLN' then jg_info_n3
end as v14_func_amount
, case when jg_info_v16 = 'tns:' then null
else jg_info_v16
end as v16_box
, case when jg_info_v16 = 'tns:' then null
else jg_info_n30
end as v16_amount
, case when jg_info_v16 like 'tns:P_14%' and jg_info_v32 <> 'PLN' then jg_info_v16||'W'
end as v16_func_box
, case when jg_info_v16 like 'tns:P_14%' and jg_info_v32 <> 'PLN' then jg_info_n4
end as v16_func_amount
from XXSAMPLE2
where jg_info_v1 IN ('AR', 'AP')
and jg_info_n11 = 859639;
which gets:
INVOICE_ID INVOICE_TYPE CURRENCY_CODE V14_BOX V14_AMOUNT V14_FUNC_BOX V14_FUNC_AMOUNT V16_BOX V16_AMOUNT V16_FUNC_BOX V16_FUNC_AMOUNT
---------- ------------ ------------- ---------- ---------- ------------ --------------- ---------- ---------- ------------ ---------------
859639 KOREKTA EUR tns:P_13_4 -94
859639 KOREKTA EUR tns:P_13_5 -32 tns:P_14_5 -3.52 tns:P_14_5W -13.49
859639 KOREKTA EUR tns:P_13_3 30 tns:P_14_3 3.6 tns:P_14_3W 13.79
And you can then unpivot that, with a single command:
select invoice_id, invoice_type, box, amount
from (
select jg_info_n11 invoice_id
, jg_info_v21 invoice_type
, jg_info_v32 currency_code
, case when jg_info_v14 = 'tns:' then null
else jg_info_v14
end as v14_box
, case when jg_info_v14 = 'tns:' then null
else jg_info_n15
end as v14_amount
, case when jg_info_v14 like 'tns:P_14%' and jg_info_v32 <> 'PLN' then jg_info_v14||'W'
end as v14_func_box
, case when jg_info_v14 like 'tns:P_14%' and jg_info_v32 <> 'PLN' then jg_info_n3
end as v14_func_amount
, case when jg_info_v16 = 'tns:' then null
else jg_info_v16
end as v16_box
, case when jg_info_v16 = 'tns:' then null
else jg_info_n30
end as v16_amount
, case when jg_info_v16 like 'tns:P_14%' and jg_info_v32 <> 'PLN' then jg_info_v16||'W'
end as v16_func_box
, case when jg_info_v16 like 'tns:P_14%' and jg_info_v32 <> 'PLN' then jg_info_n4
end as v16_func_amount
from XXSAMPLE2
where jg_info_v1 IN ('AR', 'AP')
and jg_info_n11 = 859639
)
unpivot (
(box, amount)
for x in (
(v14_box, v14_amount) as 1,
(v14_func_box, v14_func_amount) as 2,
(v16_box, v16_amount) as 3,
(v16_func_box, v16_func_amount) as 4
)
);
which gets:
INVOICE_ID INVOICE_TYPE BOX AMOUNT
---------- ------------ ------------ ----------

I was able to get an Answer from the amazing people over at AskTom Forum and below are the details:
When you have multiple sets of columns you want to unpivot, chaining unpivot operations multiplies rows in your results.
The trick is to provide a comma-separated list of the columns you want to appear in your results before FOR. And each group of source columns that will provide these values. For example:
unpivot include nulls (
( trx_box, entered_amt_values, func_amt ) for cols in (
( jg_info_v14, jg_info_n15, jg_info_n3 ) as 'trx_box',
( jg_info_v16, jg_info_n30, jg_info_n4 ) as 'func_amt'
)
)
Which gives:
with rws as (
select jg_info_v14
, jg_info_n3
, jg_info_n11
, jg_info_n4
, jg_info_n15
, jg_info_v16
, jg_info_v21
, jg_info_n30
, jg_info_v32
from xxsample2
where jg_info_v1 IN ('AR', 'AP')
)
select jg_info_n11,
jg_info_v21,
jg_info_v32,
case
when trx_box like 'tns:P_14%' and jg_info_v32 <> 'PLN'
then trx_box || 'W'
else null
end functional_box,
entered_amt_values,
func_amt
from rws
unpivot include nulls (
( trx_box, entered_amt_values, func_amt ) for cols in (
( jg_info_v14, jg_info_n15, jg_info_n3 ) as 'trx_box',
( jg_info_v16, jg_info_n30, jg_info_n4 ) as 'func_amt'
)
)
where jg_info_n11 = 859639
and trx_box <> 'tns:';
And below are the results:
JG_INFO_N11 JG_INFO_V21 JG_INFO_V32 FUNCTIONAL_BOX ENTERED_AMT_VALUES FUNC_AMT
859639 KOREKTA EUR <null> -94 -360.12
859639 KOREKTA EUR <null> -32 -122.6
859639 KOREKTA EUR tns:P_14_5W -3.52 -13.49
859639 KOREKTA EUR <null> 30 114.93
859639 KOREKTA EUR tns:P_14_3W 3.6 13.79
It's pretty close to what I want to accomplish, which really helped me understand how multi-group Unpivots work.
