SQLLoader - using more than 1 function in a single field

Question

Hi.
I have problem with sqlloader. i'm trying to call 2 function (DECODE and NPCS_FINBOUND_CTRL) for field type like below
LOAD DATA
INFILE "TEST.txt"
APPEND
INTO TABLE NPCS_INBOUND_NIZ
TYPE POSITION(1:1) "DECODE(:TYPE,1,2,:TYPE)" "NPCS_FINBOUND_CTRL(:TYPE,NPCS_FSEQCTRL('P_GFA','0',:TYPE),NPCS_FSEQC
TRL('P_GFA','1',:TYPE),NPCS_TRANS_ID_SEQ.nextval,null,null,null)"
,FILE_ID "NPCS_FSEQCTRL('P_GFA','0',DECODE(:TYPE,1,2,:TYPE))"
,BATCH_ID "NPCS_FSEQGET('P_GFA','1',:TYPE)"
,TRANS_ID "TRANS_ID_SEQ.nextval"
,DATA POSITION(1:160)

SQL*Loader-350: Syntax error at line 6.
Expecting valid column specification, "," or ")", found "DECODE(:TYPE,1,2,:TYPE)".
