WHERE
UDF.USERDEFINEDFIELDKEY = WOUD.USERDEFINEDFIELDKEY
AND UDF.LABEL IN('Project Manager','Team Manager','Team Lead','Customer Coordinator','Avionics Lead','Interior Lead','Inspector','Mechanical Engineer','Avionics Engineer','Planner','Parts Coordinator','Report Logo/Header Selection')
AND UDF.DELETED = 0
AND WOUD.DELETED = 0

WHERE
WO.WORKORDERKEY = UDF1.WORKORDERKEY(+);

Answer 1

maybe this example might be of some help.
SQL> select * from pivot_tab;
      COL1 COL2
         1 a
         1 b
         1 c
         2 h
         2 h
SQL>
SQL>
SQL> select p.col1,
  2         substr(max(substr(sys_connect_by_path (p.col2,','),2)),1,60)
  3         as col2
  4    from (select col1,
  5                 col2,
  6                 row_number() over (partition by col1 order by col1, col2) rn
  7            from pivot_tab) p
  8  start with p.rn = 1
  9  connect by p.rn = prior p.rn + 1
10  and prior p.col1 = p.col1
11  group by col1;
      COL1 COL2
         1 a,b,c
         2 h,h
