LVL or Goup by wise Sum

Question

I have 4 column ca_code, ca_title, ca_lvl, trs_db
SQL> desc tb_all;
Name                                      Null?    Type
CA_CODE                                            VARCHAR2(20)
CA_TITLE                                           VARCHAR2(100)
CA_LVL                                             NUMBER(1)
TRS_DB                                             NUMBER(15,3)The data of this table
SQL> Select * from Tb_all order by ca_code ;
CA_CODE              CA_TITLE                                CA_LVL     TRS_DB
5                    INCOME & REVENUES                            1   
51                   INCOME & REVENUES                            2   
5101                 SERVICES INCOME                              3   
510101               SERVICES INCOME                              4   
510101001            SERVICES & FACILITATION INCOME               5    140,000
510102               OTHER INCOME                                 4   
510102001            WATER SUPPLY CHARGES                         5    130,000
510103               PROFIT ON BANK DEPOSIT                       4   
510103001            PROFIT ON BANK DEPOSIT HMBL                  5    120,000
510104               GAIN/LOSS ON INVESTMENT                      4   
510104001            UN-REALIZED CAPITAL GAIN ON INVESTM          5    110,000Trs_DB has values only where ca_LVL = 5
When I use this query
select ca_code,ca_title,ca_lvl,sum(trs_db) trs_db
from tb_all
group by ca_code,ca_title,ca_lvl;
Return these rows where trs_db is not null (only in ca_lvl =5)
510101001            SERVICES & FACILITATION INCOME               5    140,000
510102001            WATER SUPPLY CHARGES                         5    130,000

510104001            UN-REALIZED CAPITAL GAIN ON INVESTM          5    110,000I need this query.

I have not tested this code. It might work.
select ca_code, ca_title, ca_lvl, trs_db, case when ca_code = col_1
                                               then sum(nvl(trs_db,0)) over(partition by col_1)
                                               when ca_code = col_2
                                               then sum(nvl(trs_db,0)) over(partition by col_2)
                                               when ca_code = col_3
                                               then sum(nvl(trs_db,0)) over(partition by col_3)
                                               when ca_code = col_4
                                               then sum(nvl(trs_db,0)) over(partition by col_4)
                                               when ca_code = col_5
                                               then sum(nvl(trs_db,0)) over(partition by col_5)
                                               when ca_code = col_6
                                               then sum(nvl(trs_db,0)) over(partition by col_6)
                                               when ca_code = col_7
                                               then sum(nvl(trs_db,0)) over(partition by col_7)
                                               when ca_code = col_8
                                               then sum(nvl(trs_db,0)) over(partition by col_8)
                                               when ca_code = col_9
                                               then sum(nvl(trs_db,0)) over(partition by col_9)
                                           End Sum_value
from
select CA_CODE,  CA_TITLE, CA_LVL, TRS_DB,
       substr(ca_code,1,1) col_1,
       substr(ca_code,1,2) col_2,
       substr(ca_code,1,3) col_3,
       substr(ca_code,1,4) col_4,
       substr(ca_code,1,5) col_5,
       substr(ca_code,1,6) col_6,
       substr(ca_code,1,7) col_7,
       substr(ca_code,1,8) col_8,
