Problem on Dynamic Query Report

Question

Hello,
I need to perform a report depend on the user who is accesing to my application,
I am using the following query:
declare
q varchar2(4000);
v_usuario varchar2(10);
begin
SET v_usuario = (CASE
WHEN :P101_USERNAME='janet' THEN v_usuario = 'JA'
WHEN :P101_USERNAME='cesar' THEN v_usuario = 'CC'
WHEN :P101_USERNAME='luisjavier' THEN v_usuario = 'LT'
WHEN :P101_USERNAME='mauricio' THEN v_usuario = 'MO'
WHEN :P101_USERNAME='enrique' THEN v_usuario = 'EH'
ELSE ' ')
q:=' select p.cliente, ';
q:=q||' p.partner, ';
q:=q||' p.channel_mgr, ';
q:=q||' p.fm_sales_rep, ';
q:=q||' p.status, ';
q:=q||' p.sc_leader, ';
q:=q||' p.sector, ';
q:=q||' p.fecha_inicio, ';
q:=q||' from adminorv.proyectosongoing p ';
q:=q||' where p.sc_leader = v_usuario';
return q;
end;
However, I got this error:1 error has occurred
Query cannot be parsed within the Builder. If you believe your query is syntactically correct, check the ''generic columns'' checkbox below the region source to proceed without parsing. ORA-06550: line 1, column 9: PLS-00103: Encountered the symbol "" when expecting one of the following: begin function package pragma procedure subtype type use form current cursor
Somebody can give a hint?

You have a bunch of syntax errors there.
The code should look more like this:
declare
q varchar2(4000);
v_usuario varchar2(10);
begin
v_usuario := (CASE
WHEN :P101_USERNAME='janet' THEN  'JA'
WHEN :P101_USERNAME='cesar' THEN  'CC'
WHEN :P101_USERNAME='luisjavier' THEN  'LT'
WHEN :P101_USERNAME='mauricio' THEN  'MO'
WHEN :P101_USERNAME='enrique' THEN  'EH'
ELSE ' ' END);
q:=' select p.cliente, ';
q:=q||' p.partner, ';
q:=q||' p.channel_mgr, ';
q:=q||' p.fm_sales_rep, ';
q:=q||' p.status, ';
q:=q||' p.sc_leader, ';
q:=q||' p.sector, ';
q:=q||' p.fecha_inicio ';
q:=q||' from adminorv.proyectosongoing p ';
q:=q||' where p.sc_leader = v_usuario';
return q;
end;But I don't see why you are using dynamic SQL and a function returning a query here.
That could be done with just a simple query like this:
select p.cliente, p.partner, p.channel_mgr, p.fm_sales_rep, p.status, p.sc_leader,
       p.sector, p.fecha_inicio
  from adminorv.proyectosongoing p
where p.sc_leader = CASE WHEN :P101_USERNAME = 'janet' THEN 'JA'
                          WHEN :P101_USERNAME = 'cesar' THEN 'CC'
                          WHEN :P101_USERNAME = 'luisjavier' THEN 'LT'
                          WHEN :P101_USERNAME = 'mauricio' THEN 'MO'
                          WHEN :P101_USERNAME = 'enrique' THEN 'EH'
                          ELSE ' '
                      END
