View is Created with the Wrong Datatype

Question

Hello All,
One of the rows I select while creating a view is a number.
Oracle Creates the view with the selected field as a varchar.
Why would oracle change a datatype of a selected column in the expressed view?
Here is the code:
CREATE OR REPLACE VIEW CC_V
(CO_ON_DATE, NAME, EMP_NO, CC_NUMBER, EXPENSE_DT,
CC_AMT, CC_PROC_DT, EXPORT_DT, CURR_COMPANY, EXPORT_HDR_STATUS)
AS
(select
sl_emp_utility_pkg.company_on_date(a.er_employee_number,b.EXLI_EXPENSE_ITEM_DATE),
c.USER_LAST_NAME||','||c.USER_FIRST_NAME name,
a.er_employee_number emp_no,
'** '||substr(b.exli_cc_card_number,13,4) cc_number,
b.EXLI_EXPENSE_ITEM_DATE expense_dt,
b.exli_alloc_base_amt cc_amt,
new_time(a.export_hdr_status_datetime,'GMT','CDT') cc_proc_dt,
new_time(a.export_create_date,'GMT','CDT') export_dt,
a.export_hdr_status, --this is the column
c.system_code_1 curr_company
from
aler_expense_export_header a,
aler_expense_export_line b,
alco_user c
where
a.export_er_hdr_id = b.export_er_hdr_id and
a.export_hdr_status in (0,2,4) and
c.user_login = a.er_user_login and
b.exli_line_is_personal_flag = 0 and
b.exli_payment_type_label = 'Corporate Charge Card' and
er_corp_charge_total <> 0)
Thanks for any help,
Bradley

sorry I did not see the comment but look at this .your sequence is not correct
CREATE OR REPLACE VIEW cc_v (co_on_date,
                             NAME,
                             emp_no,
                             cc_number,
                             expense_dt,
                             cc_amt,
                             cc_proc_dt,
                             export_dt,
                            curr_company,
                            export_hdr_status
AS
   (SELECT sl_emp_utility_pkg.company_on_date (a.er_employee_number,
                                               b.exli_expense_item_date
           c.user_last_name || ',' || c.user_first_name NAME,
           a.er_employee_number emp_no,
           '** ' || SUBSTR (b.exli_cc_card_number, 13, 4) cc_number,
           b.exli_expense_item_date expense_dt, b.exli_alloc_base_amt cc_amt,
           NEW_TIME (a.export_hdr_status_datetime, 'GMT', 'CDT') cc_proc_dt,
           NEW_TIME (a.export_create_date, 'GMT', 'CDT') export_dt,
         a.export_hdr_status, --this is the column
                               c.system_code_1 curr_company
      FROM aler_expense_export_header a,
           aler_expense_export_line b,
           alco_user c
     WHERE a.export_er_hdr_id = b.export_er_hdr_id
       AND a.export_hdr_status IN (0, 2, 4)
       AND c.user_login = a.er_user_login
       AND b.exli_line_is_personal_flag = 0
       AND b.exli_payment_type_label = 'Corporate Charge Card'
