Answer 1

I guessed... This looks like a case of String Aggregation.
Something like this?
(Only on versions > 11gR2)
ranit@XE11GR2>> ed
Wrote file afiedt.buf
  1  with test_table as
  2  (
  3  select 1 id, '3P SUPPORT' data from dual UNION ALL
  4  select 1 id, 'ALLIED SVCS' data from dual UNION ALL
  5  select 2 id, 'AS-CDN' data from dual UNION ALL
  6  select 2 id, 'AS-DVSUP' data from dual UNION ALL
  7  select 3 id, 'BCS' data from dual UNION ALL
  8  select 3 id, 'BES' data from dual UNION ALL
  9  select 3 id, 'BMS' data from dual UNION ALL
10  select 3 id, 'CAM' data from dual
11  )
12  --
13  -- Test data
14  --
15  select
16     id,
17     LISTAGG(data,',') WITHIN GROUP(order by data) data
18  from test_table
19* group by id
ranit@XE11GR2>> /
  ID DATA
   1 3P SUPPORT,ALLIED SVCS
   2 AS-CDN,AS-DVSUP
   3 BCS,BES,BMS,CAM
The rows are grouped by column "Id" and String-aggregation is done for column "Data".
Below solution works in all Oracle versions:
ranit@XE11GR2>> ed
Wrote file afiedt.buf
  1  with test_table as
  2  (
  3  select 1 id, '3P SUPPORT' data from dual UNION ALL
  4  select 1 id, 'ALLIED SVCS' data from dual UNION ALL
  5  select 2 id, 'AS-CDN' data from dual UNION ALL
  6  select 2 id, 'AS-DVSUP' data from dual UNION ALL
  7  select 3 id, 'BCS' data from dual UNION ALL
  8  select 3 id, 'BES' data from dual UNION ALL
  9  select 3 id, 'BMS' data from dual UNION ALL
10  select 3 id, 'CAM' data from dual
11  )
12  --
13  -- Test data
14  --
15  select
16     id,
17     RTRIM(
18             XMLAgg(XMLElement(x,data||',')).extract('//text()')
19             ,',') data
20  from test_table
21* group by id
ranit@XE11GR2>> /
  ID DATA
   1 3P SUPPORT,ALLIED SVCS
   2 AS-CDN,AS-DVSUP
   3 BCS,CAM,BMS,BES
