FGAC predicate not taking effect.

Hi,

          I have recently created FGAC policy on GL_JE_HEADERS table in Oracle Apps with the following function returning the Predicate

create or replace function f_policy_gl_fn

        

-- Function must have the following parameters

         (schema in varchar2, tab in varchar2)

        

-- Function will return a string that is used as a WHERE clause                     

return varchar2  authid current_user

   

as

v_user          varchar2(100);

out_string      varchar2(400) default '1=2 ';

-- out_string will be the return value.

-- It is initialized to '1=2' because 'WHERE 1=2' means 'Nothing to access'

begin

-- get session user

  v_user := lower(sys_context('userenv','CURRENT_USER'));
