ora-31626 job does not exist

I am having a procedure (which was bascially copied from the pl/sql query generated from OEM(maintenance->Export to export files) when you want to export a schema)..

If i run the pl/sql as a script it works in TOAD perfecly fine..however if i create the same script as a procedure it errors out in line...( i am logged in as that schema user and the schema has permissions to read,write on the data pump dump directory)
My aim is to run this procedure as a job and do export at regular intervals.....

ORA-31626: job does not exist
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 79

Actually, this is somewhat of a different issue and it has to do with user privileges. The PL/SQL code uses rights granted to roles, but when you use a procedure you need to grant rights directly to the user.

More specifically, see this link: http://download.oracle.com/docs/cd/B14117_01/appdev.101/b10800/dcimethpls.htm#sthref170

For the compilation of the procedure or package, the owner of the procedure or package must have been explicitly granted the necessary object privileges for all objects referenced within the body of the code. The owner cannot have obtained required privileges through roles.
