Answer 1

The PLS-00436 is an annoying error message indeed.
On 10g:
rwijk@ORA10GR2> create table t2

  3    act number,
  4     is_p varchar2(1),
  5    other varchar2(20)
  6  );
Tabel is aangemaakt.

FOUT in regel 9:
.ORA-06550: Regel 9, kolom 35:
PLS-00436: Implementatierestrictie: kan niet verwijzen naar velden van BULK In-BIND-recordtabel..
ORA-06550: Regel 9, kolom 35:

PL/SQL: SQL Statement ignored.You can code it slightly different using SQL object types like this, to make the code work in 10g:
rwijk@ORA10GR2> create type t2_otype is object
  2  ( seq_id number
  3  , act number
  4  , is_p varchar2(1)
  5  , other varchar2(20)
  6  );
  7  /
Type is aangemaakt.
rwijk@ORA10GR2> create type t2s is table of t2_otype;
  2  /
Type is aangemaakt.
rwijk@ORA10GR2> declare
  2    cursor c1 is select t2_otype(seq_id,act,is_p,other) from t2 ;
  3    t t2s;
  4  begin
  5    open c1;
  6    fetch c1 BULK collect into t;
  7    forall i in 1..t.count
  8      insert into t3(seq_id) values (treat(t(i) as t2_otype).seq_id);
  9    close c1;
10  end;
11  /
PL/SQL-procedure is geslaagd.On 11g, as said, you don't have to modify your code:
rwijk@ORA11G> create table t2
  2  ( seq_id number,
  3    act number,
  4     is_p varchar2(1),
  5    other varchar2(20)
  6  );
Tabel is aangemaakt.
rwijk@ORA11G> insert into t2 values(1,2,'N','Test 1');
1 rij is aangemaakt.
rwijk@ORA11G> create table t3
  2  ( seq_id number
  3   -- ,act number
  4   --  ,is_p varchar2(1)
  5  );
Tabel is aangemaakt.
rwijk@ORA11G> declare
  2   type t2_r is table of t2%ROWTYPE;
  3   cursor c1 is select * from t2 ;
  4    t t2_r;
  5  begin
  6    open c1;
  7    fetch c1 BULK collect into t;
  8    forall i in 1..t.count
  9     insert into t3(seq_id) values (t(i).seq_id);
10    close c1;

PL/SQL-procedure is geslaagd.Regards,
