Hi Ranit ,
thanks for your response , i disagree with you lets take a look at those scenarios :
scenario 1 :
show user
user is "NAAMA"
create materialized view log on users with primary key;
show user
user is "TEST"
CREATE MATERIALIZED VIEW users_mv
BUILD immediate
REFRESH FAST ON COMMIT  
AS
SELECT
user_id,
user_name  ,
user_password , 
naama.get_name(user_id) FIRST_name
FROM naama.users
ORA-12054: cannot set the ON COMMIT refresh attribute for the materialized view.
according to this there is nothing to do to the primary key,scenarion 2:
show user
user is "NAAMA"
create MATERIALIZED VIEW LOG ON USERS WITH rowid.
create or replace function get_name (user_name_in IN varchar2) return varchar2
is
begin
return 'NAAMA';
end  get_name;
show user
user is "TEST"
CREATE MATERIALIZED VIEW users_mv
BUILD immediate
REFRESH FAST ON COMMIT with primary key
AS
SELECT
user_name  ,
user_password , 
naama.get_name(user_name) FIRST_name
FROM naama.users;
ORA-12054: cannot set the ON COMMIT refresh attribute for the materialized view.scenarion 3:
show user
user is "NAAMA"
create MATERIALIZED VIEW LOG ON USERS WITH rowid.
show user
user is "TEST"
CREATE MATERIALIZED VIEW users_mv
BUILD immediate
REFRESH FAST ON COMMIT   WITH rowid
AS
SELECT
user_name  ,
user_password , 
SUBSTR(user_name,1,5)
FROM naama.USERS;
materialized view created.so we cannot say that the mview has problem using functions.
What seems to be the problem ?
