SQL Loader to append data in same table but using differnet WHEN clauses

Question

In my data file i have a header record and a detail record identified by Record_type = 1 and 2 respectively.
The Database table has all the columns to capture detail records but i want to capture jus one column of header record now also in my existing table. So i have added that column (DATA_DATE)in my table but how to capture that value ?
im writing my control file using two WHEN clauses, something like -
load data
into table t_bdn
append
when RECORD_TYPE = '2'
FIELDS TERMINATED BY "|" TRAILING NULLCOLS
SEQUENCE_NO
, RECORD_TYPE
, DISTRIBUTOR_CODE
, SUPPLIER_CODE
, SUPPLIER_DISTRIBUTOR_CODE
, DISTRIBUTOR_SKU
, SUPPLIER_SKU
when RECORD_TYPE = '1'
FIELDS TERMINATED BY "|" TRAILING NULLCOLS
SEQUENCE_NO FILLER
, RECORD_TYPE FILLER
, CREATE_DATE FILLER
, DATA_DATE "NVL(to_date(:DATA_DATE, 'YYYY/MM/DD'),to_date('9999/12/31', 'YYYY/MM/DD'))"
im getting error " expecting INTO and foung WHEN RECORD_TYPE = '1' "
if i give iNTO second time it will append a new row altogether in my table but i want the same row to be updated with this DATA_DATE value coming from RECORD_TYPE =1 and header record has 4 delimited data text fields only and i am interested in fetching just the 4th column..
KIndly suggest what to do ?

Ravneek, I could be wrong but sqlldr is a 'load' program, that is, it inserts data. I am unaware of any ability to update existing rows as you seem to want. What you appear to want to do is more the job of a merge statement.
I would look at writing a pro* language, a .net, or a java program to perform inserts where some or all of the newly inserted rows are also to be updated.
From the manual: (Oracle® Database Utilities 10g Release 2 (10.2) Part Number B14215-01)
Updating Existing Rows
The REPLACE method is a table replacement, not a replacement of individual rows. SQL*Loader does not update existing records, even if they have null columns. To update existing rows, use the following procedure:
1. Load your data into a work table.
2. Use the SQL language UPDATE statement with correlated subqueries.
3. Drop the work table.
