Trouble with Dbms_DataPump.Open

Question

Hello eveyrone, I always get a "ORA-31626: job does not exist" when i try this simple code :
DECLARE
hand NUMBER;
BEGIN
hand := Dbms_DataPump.Open('IMPORT', 'FULL',NULL,'marcotte_imp');
END;
Im trying with a user that have all the privileges checked in the privileges pane in the users page.
What exactly im missing ?
Thx !

Also found these from metalink;
Note:262557.1 -> You attempt to attach to a job that already completed or was aborted: the master table containing the list of objects to be exported has therefore already been dropped.
Note:272492.1 -> The size of the undo tablespace is not sufficient enough to complete this task.
Note:315488.1 -> No CREATE TABLE privilege explicitly granted to exporting schema. Solutions;
1) Explicitly grant privileges, e.g.:
grant create session, create table, create procedure, exp_full_database,
imp_full_database to testuser;
grant read, write on directory my_dump_dir to <users>;
2) Make sure that GRANT must be done as a separate grant and not through a ROLE.
