sqlloader skips characters during data load into table - oracle

Question

using the control file below to load data
LOAD DATA
INFILE '/c/Transaction.txt'
INTO TABLE tab1 APPEND WHEN (1:1) = 'D'
(RUN_ID "RUN_ID_SEQ.NEXTVAL"
,RUN_DATE_TIME "SYSDATE"
)
INTO TABLE tab2 TRUNCATE WHEN(1:1) <> 'D'
FIELDS TERMINATED BY '|' TRAILING NULLCOLS
(
DEALER_NUMBER
,TRAN_CODE
,TRAN_AMOUNT "TO_NUMBER(:PL818_TRAN_AMOUNT,'999999.99')"
,TRAN_DATE "TO_DATE(:PL818_TRAN_DATE,'DD-MM-YYYY')"
)
This is the data set
DEALER_ID|TRAN_TYPE_CODE|TRAN_AMOUNT|TRAN_DATE
203113|34|1000.50|12-07-2022
No errors during load. Data loads correctly into the first table but first two characters are skipped when loading data into second table, table data looks like this. What could be causing this?

Sample tables:
SQL> desc tab1
Name Null? Type
----------------------------------------- -------- ----------------------------
RUN_ID NUMBER
RUN_DATE_TIME DATE
SQL> desc tab2
Name Null? Type
----------------------------------------- -------- ----------------------------
DEALER_NUMBER NUMBER
TRAN_CODE NUMBER
TRAN_AMOUNT NUMBER
TRAN_DATE DATE

Control file; note position(1) when loading into tab2. You must use it when loading data into different tables, using the same control file:
LOAD DATA
INFILE *
INTO TABLE tab1 APPEND WHEN (1:1) = 'D'
(RUN_ID "RUN_ID_SEQ.NEXTVAL"
,RUN_DATE_TIME "SYSDATE"
)
INTO TABLE tab2 TRUNCATE WHEN(1:1) <> 'D'
FIELDS TERMINATED BY '|' TRAILING NULLCOLS
(
DEALER_NUMBER position(1) --> here
,TRAN_CODE
,TRAN_AMOUNT "TO_NUMBER(:TRAN_AMOUNT,'999999.99')"
,TRAN_DATE "TO_DATE(:TRAN_DATE,'DD-MM-YYYY')"
)
